DETAILED DESCRIPTION OF THE INVENTION

[0014] In aquatic life farms for fish and other aquatic organisms, there is a demand for feeding aquatic organisms located at a specific depth. Conventional feeding devices are designed to feed fish by dropping food from above the water, making it difficult to feed fish at a specific depth in the water. This embodiment describes a feeder that makes it possible to feed aquatic organisms at a specific depth. This embodiment also describes a fish-lifting device that makes it possible to land aquatic organisms at a specific depth.

[0015] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0016] FIG. 1 shows a schematic diagram of an example of a feeder 100. The feeder 100 is a device for feeding aquatic organisms. For example, the feeder 100 may feed aquatic organisms that are the subject of aquaculture. The feeder 100 feeds, for example, fish. However, this is not a limitation, and the feeder 100 may feed any aquatic organism that is the subject of aquaculture.

[0017] The feeder 100 comprises a food receiving part 110 and a tubular member 120. The food receiving part 110 is placed above the water, and the tubular member 120 is placed underwater.

[0018] For example, the bait receiving part 110 and the cylindrical member 120 are installed on the base 130, and the base 130 floats on the water, so that the bait receiving part 110 is placed on the water and the cylindrical member 120 is placed underwater. The base 130 may be provided with one or more floats to increase buoyancy.

[0019] The bait receiving unit 110 receives bait 200 for aquatic organisms. The bait receiving unit 110 may have a receiving port 112 that receives the bait 200. In the example shown in Fig. 1, the receiving port 112 receives a cartridge 210 that contains the bait 200. Note that the receiving port 112 may also receive the bait 200 directly without using the cartridge 210.

[0020] The cylindrical member 120 has a hollow cylindrical portion 122, an opening 124 provided at one end of the cylindrical portion 122, and an opening 126 provided at the other end of the cylindrical portion 122. The opening 124 and the bait receiving portion 110 are connected, and the opening 124 receives bait received by the bait receiving portion 110. The opening 126 is disposed in water. The opening 124 may be an example of a first opening. The opening 126 may be an example of a second opening.

[0021] The bait received by the bait receiving section 110 is released into the water through the opening 124, the tubular section 122, and the opening 126. Until it reaches the opening 126, the tubular section 122 reduces the dissolution of the bait 200 and prevents the bait 200 from flowing sideways, allowing the bait 200 to reach a predetermined depth.

[0022] The feeder 100 may be configured to change the depth position of the opening 126 in water. For example, the position of the base 130 may be configured to be movable in the vertical direction relative to the food receiving portion 110 and the tubular member 120. This allows the depth of the opening 126 to be made shallower, for example, by moving the position of the base 130 downward. Also, for example, the length of the tubular portion 122 may be adjustable. For example, the tubular portion 122 may have a bellows structure. For example, the tubular portion 122 may have a structure in which multiple tubes are slidably connected. This makes it possible to appropriately change the depth to which the food 200 reaches.

[0023] The feeder 100 may be equipped with a mechanism for applying pressure to the food 200 received by the food receiving portion 110 so that the food 200 reaches the opening 126 via the opening 124 and the tube portion 122. The feeder 100 may be equipped with, for example, a mechanism for directly pressing the food 200 with a push rod. The feeder 100 may be equipped with, for example, a mechanism for pressing the food 200 with air pressure. The feeder 100 may be equipped with, for example, a mechanism for pressing the food 200 with water pressure.

[0024] Figure 2 schematically illustrates an example of a feeder 100. The feeder 100 illustrated in Figure 2 includes a pressure regulator 140 connected to the food receiving portion 110. The pressure regulator 140 applies pressure to the food 200 received by the food receiving portion 110 so that the food 200 reaches the opening 126 via the opening 124 and the tube portion 122. The pressure regulator 140 may apply pressure to the food 200 in the cartridge 210. The pressure regulator 140 may apply air pressure to the food 200. The pressure regulator 140 may apply water pressure to the food 200.

[0025] The opening 126 has a cutting portion 1262 that cuts the bait 200. In the example shown in Figure 2, the cutting portion 1262 has a mesh member. The bait 200 is cut by being pressed against the mesh member by the pressure applied by the pressure regulator 140.

[0026] With this configuration of the feeder 100, by placing the cartridge 210 containing the bait 200 in the bait receiving section 110, the bait 200 divided into desired sizes can be released to a predetermined depth in the water. Furthermore, after the release of the bait 200 is complete, additional bait can be easily released to a predetermined depth by replacing the cartridge 210. These features improve the efficiency of feeding.

[0027] The bait 200 solidified into the shape of the cartridge 210 is pressed against the mesh member of the cutting unit 1262 to be shredded. After advancing a certain distance, the bait 200 naturally cuts in a direction perpendicular to the direction of advancement. This results in the desired size. For greater reliability, the cutting unit 1262 may further include a cutter 1264 that cuts the bait 200 in a direction different from the longitudinal direction of the tubular member 120. For example, the cutter 1264 cuts the bait 200 along a plane perpendicular to the longitudinal direction of the tubular member 120. For example, the cutter 1264 cuts the bait 200 projected from the cutting unit 1262 by a predetermined length in response to the pressure applied by the pressure regulator 140, in conjunction with the pressure applied by the pressure regulator 140. Examples of cutting methods include, but are not limited to, cutting with a linear member, cutting with a blade, and cutting with a laser. By including the cutter 1264 in the cutting unit 1262, the bait 200 can be more reliably cut to the desired size.

[0028] Figure 3 shows a schematic diagram of an example of the configuration of a feeder 100. The feeder 100 shown in Figure 3 includes a food receiving part 110, a tubular member 120, a base 130, and a pressure regulator 140. The food receiving part 110 and the tubular member 120 are mounted relative to the base 130. The base 130 may be located above the water surface 20, the food receiving part 110 may be located above the water, and the tubular member 120 may be located underwater.

[0029] The pressure regulator 140 has a pressure adjustment unit 141. The pressure adjustment unit 141 applies pressure to the bait 200 received by the bait receiving unit 110 so that the bait 200 reaches the opening 126 via the opening 124 and the tube portion 122. For example, the pressure adjustment unit 141 applies physical pressure to the bait 200 using a push rod or the like. For example, the pressure adjustment unit 141 applies air pressure to the bait 200. The pressure regulator 140 may have a compressor. For example, the pressure adjustment unit 141 applies water pressure to the bait 200.

[0030] The opening 126 is provided with a cutting section 1262 having a mesh member, and the bait 200 is cut by being pressed against the mesh member by the pressure applied by the pressure adjusting section 141. The cut bait 200 is released into the water at the depth where the opening 126 is located.

[0031] The length of the tube portion 122 may be adjustable. For example, the tube portion 122 has a bellows structure. For example, the tube portion 122 has a structure in which a plurality of tubes are slidably connected. This allows the depth at which the bait 200 is released to be changed as needed.

[0032] Figure 4 shows a schematic diagram of an example of the configuration of feeder 100. Here, differences from feeder 100 shown in Figure 3 will be mainly explained. In the example shown in Figure 4, feeder 100 includes camera 150, and pressure regulator 140 includes image acquisition unit 142, situation determination unit 143, and setting unit 144.

[0033] Camera 150 is disposed on the other end side of tube portion 122, i.e., on the opening 126 side of tube portion 122. Camera 150 captures an image of the periphery of opening 126. Camera 150 may be a camera that captures an image of a limited range. Camera 150 may also be an omnidirectional camera that can capture images in all directions.

[0034] The image acquisition unit 142 acquires the captured image captured by the camera 150. The image acquisition unit 142 may receive the captured image from the camera 150. The pressure regulator 140 and the camera 150 may be connected by wire or wirelessly.

[0035] The situation determination unit 143 determines the surrounding situation of the opening 126 by analyzing the captured image acquired by the image acquisition unit 142. For example, the situation determination unit 143 determines whether or not an aquatic organism is present around the opening 126. For example, the situation determination unit 143 determines the position of the aquatic organism around the opening 126. The situation determination unit 143 may track the aquatic organism. For example, the situation determination unit 143 determines the size of the aquatic organism around the opening 126. When a single aquatic organism is located around the opening 126, the situation determination unit 143 may determine the size of the single aquatic organism. When multiple aquatic organisms are located around the opening 126, the situation determination unit 143 may determine the size of each of the multiple aquatic organisms, or may determine the average size of the multiple aquatic organisms. For example, the situation determination unit 143 determines the number of aquatic organisms around the opening 126. For example, the situation determination unit 143 determines the type of aquatic organism located around the opening 126. When a single aquatic organism is located around the opening 126, the situation determination unit 143 may determine the type of the single aquatic organism. When multiple aquatic organisms are located around the opening 126, the situation determination unit 143 may determine the type of each of the multiple aquatic organisms.

[0036] The situation determination unit 143 may determine the posture of an aquatic creature around the opening 126. When a single aquatic creature is located around the opening 126, the situation determination unit 143 may determine the posture of the single aquatic creature. When multiple aquatic creatures are located around the opening 126, the situation determination unit 143 may determine the posture of each of the multiple aquatic creatures, or may determine the overall posture trend of the multiple aquatic creatures. The situation determination unit 143 may determine the movement direction of the aquatic creature around the opening 126. When a single aquatic creature is located around the opening 126, the situation determination unit 143 may determine the movement direction of the single aquatic creature. When multiple aquatic creatures are located around the opening 126, the situation determination unit 143 may determine the movement direction of each of the multiple aquatic creatures, or may determine the overall movement direction trend of the multiple aquatic creatures. For example, the situation determination unit 143 determines in which direction the fish is moving relative to the opening 126. As a specific example, the situation determination unit 143 determines whether the fish is moving toward or away from the opening 126, or whether the fish is crossing in front of the opening 126.

[0037] The pressure adjusting unit 141 may control the timing of applying pressure to the bait 200 placed in the bait receiving unit 110 based on the determination result by the situation determining unit 143. For example, the pressure adjusting unit 141 may apply pressure to the bait 200 while the situation determining unit 143 determines that an aquatic organism is present around the opening 126. This makes it possible to automatically not release the bait 200 when no aquatic organism is present around the opening 126, but to automatically release the bait 200 when an aquatic organism is present around the opening 126.

[0038] The pressure adjustment unit 141 may adjust the strength of the pressure applied to the bait 200 placed in the bait receiving unit 110 based on the determination result by the situation determination unit 143. For example, the greater the number of aquatic organisms around the opening 126, the stronger the pressure applied by the pressure adjustment unit 141 to the bait 200. By applying stronger pressure to the bait 200, the release rate of the bait 200 can be increased, which contributes to speeding up the cycle of replenishing the bait 200 in the bait receiving unit 110 and releasing the bait 200, and reduces the possibility of a shortage of the supply of bait 200 relative to the number of aquatic organisms. For example, the farther the aquatic organism is located from the opening 126, the stronger the pressure applied by the pressure adjustment unit 141 to the bait 200. By applying stronger pressure to the bait 200, the bait 200 can be made to reach a greater distance from the opening 126, increasing the likelihood that the bait 200 will reach the location of the aquatic organism. For example, the larger the size of the aquatic organism around the opening 126, the stronger the pressure that the pressure adjustment unit 141 applies to the bait 200. As described above, the bait 200 pressed against the mesh member of the cutting unit 1262 is cut into pieces by the mesh member, and after progressing a certain distance, the bait 200 naturally cuts in a direction perpendicular to the direction of travel. However, by increasing the pressure that is applied to the bait 200, the size of the bait 200 after cutting can be increased. This makes it possible to release bait 200 of a size that is appropriate for the size of the aquatic organism around the opening 126.

[0039] The cutter 1264 may adjust the cutting of the bait 200 based on the determination result by the situation determination unit 143. For example, the cutter 1264 adjusts the cutting of the bait 200 so that the size of the cut bait 200 increases as the size of the aquatic organism around the opening 126 increases. The cutter 1264 increases the size of the cut bait 200, for example, by increasing the frequency of cutting the bait 200. This makes it possible to release bait 200 of a size appropriate for the size of the aquatic organism around the opening 126.

[0040] The pressure adjusting unit 141 and the cutting machine 1264 may be configured to apply pressure to the bait 200 and cut the bait 200 in cooperation with each other based on the determination result by the situation determining unit 143. For example, the larger the size of the aquatic organism around the opening 126, the stronger the pressure the pressure adjusting unit 141 applies to the bait 200, and the longer the cutting cycle of the cutting machine 1264. This makes it possible to release bait 200 of a size appropriate for the size of the aquatic organism around the opening 126.

[0041] The setting unit 144 performs various settings. The setting unit 144 may execute various settings according to instructions from the user of the feeding apparatus 100. The setting unit 144 may acquire the user's instructions via, for example, an input device provided in the pressure regulator 140. The setting unit 144 may receive the user's instructions from, for example, a communication terminal used by the user.

[0042] The pressure adjustment unit 141 may control the timing of applying pressure to the bait 200 placed in the bait receiving unit 110 based on the setting by the setting unit 144 and the determination result by the situation determination unit 143. For example, the pressure adjustment unit 141 applies pressure to the bait 200 when the number of aquatic organisms around the opening 126 is greater than a number preset by the setting unit 144. This prevents the bait 200 from being released while the number of aquatic organisms around the opening 126 is less than the preset number, and allows the bait 200 to be released when the number is greater than the preset number, thereby enabling efficient feeding. For example, the pressure adjustment unit 141 applies pressure to the bait 200 when a type of aquatic organism preset by the setting unit 144 is located around the opening 126. This limits the release of the bait 200 to when the aquatic organism to which the bait 200 is to be given is located around the opening 126, enabling efficient feeding.

[0043] The pressure adjusting unit 141 may adjust the strength of the pressure applied to the bait 200 placed in the bait receiving unit 110 based on the setting by the setting unit 144 and the determination result by the situation determining unit 143. For example, the setting unit 144 sets the pressure strength for each type of aquatic organism, and the pressure adjusting unit 141 applies pressure to the bait 200 at a strength corresponding to the type of aquatic organism around the opening 126. This makes it possible to press the bait 200 with a strength set as appropriate for each type of aquatic organism. For example, the setting unit 144 sets the size of the bait 200 for each type of aquatic organism, and the pressure adjusting unit 141 applies a stronger pressure to the bait 200 as the size corresponding to the type of aquatic organism around the opening 126 increases. This makes it possible to release bait 200 of a size appropriate for each type of aquatic organism. For example, the setting unit 144 sets the intensity of pressure for each size of aquatic organism, and the pressure adjustment unit 141 applies pressure to the bait 200 at an intensity corresponding to the size of the aquatic organism around the opening 126. This makes it possible to press the bait 200 at an intensity set as appropriate for each size of aquatic organism. For example, the setting unit 144 sets the size of the bait 200 for each size of aquatic organism, and the pressure adjustment unit 141 applies a stronger pressure to the bait 200 as the size corresponding to the type of aquatic organism around the opening 126 increases. This makes it possible to release bait 200 of an appropriate size for each size of aquatic organism. For example, the setting unit 144 sets the intensity of pressure for each number of aquatic organisms, and the pressure adjustment unit 141 applies pressure to the bait 200 at an intensity corresponding to the number of aquatic organisms around the opening 126. This makes it possible to press the bait 200 at an intensity set as appropriate for each number of aquatic organisms. For example, the setting unit 144 sets the size of the bait 200 for each number of aquatic organisms, and the pressure adjusting unit 141 applies stronger pressure to the bait 200 as the size corresponding to the number of aquatic organisms around the opening 126 increases. This makes it possible to release bait 200 of a size appropriate for each number of aquatic organisms.

[0044] Figures 5 and 6 show a schematic diagram of an example of the configuration of feeder 100. Here, differences from feeder 100 shown in Figure 3 will be mainly explained. In the example shown in Figures 5 and 6, feeder 100 includes a switch 160, pressure regulator 140 includes a switch control unit 145, and tubular portion 122 includes an opening 128 and a cutting portion 1282. Opening 128 is located on the side of tubular portion 122. Opening 128 may be an example of a third opening. Cutting portion 1282 may include a mesh member.

[0045] The switch 160 inserts a plate-shaped member 162 into the position of the tubular portion 122 corresponding to the lower portion of the opening 128, so that the bait 200 pressed by the pressure from the pressure regulator 140 moves toward the opening 128 instead of toward the opening 126.

[0046] The switching control unit 145 switches between a state in which the bait 200 is released from the opening 126 and a state in which the bait 200 is released from the opening 128. The switching control unit 145 causes the selector 160 to insert the plate-like member 162 into the tubular portion 122, thereby putting the tubular portion 122 into a state in which the bait 200 is released from the opening 128. The switching control unit 145 causes the selector 160 to return the plate-like member 162 from the tubular portion 122, thereby putting the tubular portion 122 into a state in which the bait 200 is released from the opening 126.

[0047] By providing the feeder 100 with such a configuration, it is possible to release the bait 200 to a depth corresponding to the opening 126 or to a depth corresponding to the opening 128.

[0048] 5 and 6 show an example in which one opening 128 is provided in the tubular portion 122, but this is not limiting. A plurality of openings 128 may be provided at different positions along the length of the tubular portion 122. In this case, the switcher 160 may have plate-like members 162 at positions corresponding to each of the plurality of openings 128. By providing the feeder 100 with this configuration, it is possible to selectively release the bait 200 to a depth corresponding to the opening 126 and to a depth corresponding to each of the plurality of openings 128.

[0049] 5 and 6 may be equipped with camera 150 as shown in Fig. 4, and pressure regulator 140 may be equipped with image acquisition unit 142, situation determination unit 143, and setting unit 144. Feeder 100 may be equipped with one camera 150 that can capture images of both the periphery of opening 126 and the periphery of opening 128, or may be equipped with a camera 150 that captures images of the periphery of opening 126 and a camera 150 that captures images of the periphery of opening 128.

[0050] When the feeder 100 includes a single camera 150 capable of capturing images of both the periphery of the opening 126 and the periphery of the opening 128, the situation determination unit 143 may determine the periphery of the opening 126 and the periphery of the opening 128 by analyzing the captured image acquired by the image acquisition unit 142. The switching control unit 145 may switch between a state in which the bait 200 is released from the opening 126 and a state in which the bait 200 is released from the opening 128, based on the determination result by the situation determination unit 143. For example, when an aquatic organism is located only around either the periphery of the opening 126 or the periphery of the opening 128, the switching control unit 145 sets the state in which the bait 200 is released from the side where the aquatic organism is located, and the pressure adjustment unit 141 applies pressure to the bait 200 placed in the bait receiving unit 110. For example, the switching control unit 145 compares the number of aquatic organisms located around the opening 126 with the number of aquatic organisms located around the opening 128, and sets the state in which bait 200 is released from the one with the larger number, and the pressure adjustment unit 141 applies pressure to the bait 200 placed in the bait receiving unit 110.

[0051] When feeder 100 is equipped with camera 150 (sometimes referred to as first camera 150) that captures images of the area around opening 126 and camera 150 (sometimes referred to as second camera 150) that captures images of the area around opening 128, situation determination unit 143 may determine the area around opening 126 by analyzing the captured image acquired by image acquisition unit 142 from first camera 150, and may determine the area around opening 128 by analyzing the captured image acquired by image acquisition unit 142 from second camera 150.

[0052] Figure 7 shows a schematic diagram of one example of the configuration of a feeder 100. Here, differences from the feeder 100 shown in Figure 3 will be mainly described. The feeder 100 may also function as a water-lifting device for lifting aquatic organisms. The feeder 100 shown in Figure 7 is configured so that the cutting section 1262 can be opened and closed, and the pressure regulator 140 is equipped with an opening / closing control section 146 that controls the opening and closing of the cutting section 1262.

[0053] 7 is capable of generating both a pressing force and a suction pressure. When feeding, the pressure adjusting unit 141 generates a pressing force, causing the bait 200 contained in the bait receiving unit 110 to be released from the opening 126 via the opening 124 and the tube portion 122. When landing, the opening / closing control unit 146 opens the cutting portion 1262, and the pressure adjusting unit 141 generates a suction force to suck the aquatic organisms through the opening 126.

[0054] For example, during the cultivation period of aquatic organisms, the feeder 100 is used for feeding. Then, during the feeding stop period of the aquatic organisms, feeding by the feeder 100 is stopped, so that no food 200 is present in the tube portion 122, and during the landing period after the feeding stop period has passed, the feeder 100 is used to land the aquatic organisms.

[0055] Feeder 100 shown in Fig. 7 may further include camera 150 shown in Fig. 4, and pressure regulator 140 may further include image acquisition unit 142, situation determination unit 143, and setting unit 144. Situation determination unit 143 determines the situation around opening 126 by analyzing the captured image acquired by image acquisition unit 142. Pressure adjustment unit 141 may perform suction based on the determination result by situation determination unit 143.

[0056] Pressure adjustment unit 141 may perform suction when an aquatic organism is present around opening 126. Pressure adjustment unit 141 may not perform suction when no aquatic organism is present around opening 126, and may perform suction when an aquatic organism is present around opening 126. This makes it possible to prevent energy from being wasted by performing suction when no aquatic organism is present around opening 126.

[0057] The pressure adjustment unit 141 may perform suction when an aquatic organism to be sucked is located around the opening 126. The aquatic organism to be sucked may be an aquatic organism of a type that has been preset as an organism to be sucked by the setting unit 144. The aquatic organism to be sucked may be an aquatic organism of a size that has been preset as an organism to be sucked by the setting unit 144. The aquatic organism to be sucked may be an aquatic organism of a type and size that have been preset as organisms to be sucked by the setting unit 144. The pressure adjustment unit 141 may perform suction only when an aquatic organism to be sucked is located around the opening 126. This makes it possible to prevent an aquatic organism that is not a target from being accidentally sucked up.

[0058] The pressure adjusting unit 141 may perform suction when the aquatic organism is moving toward the opening 126. This can improve the efficiency of suction. The pressure adjusting unit 141 may not perform suction when the aquatic organism is moving away from the opening 126 or when the aquatic organism is facing away from the opening 126. This can reduce the suction force required for suction, reduce energy consumption, and prevent damage to the aquatic organism.

[0059] The pressure adjusting unit 141 may perform suction when the number of aquatic organisms around the opening 126 is greater than the number preset by the setting unit 144. The pressure adjusting unit 141 may not perform suction when the number of aquatic organisms around the opening 126 is less than the number preset by the setting unit 144, and may perform suction when the number of aquatic organisms around the opening 126 is greater than the number preset by the setting unit 144. This allows for efficient landing of the fish.

[0060] The status determination unit 143 may determine the status of the suction of aquatic organisms. When the pressure adjustment unit 141 performs suction of an aquatic organism, the status determination unit 143 may determine that an aquatic organism has been sucked in through the opening 126 by analyzing the captured image acquired by the image acquisition unit 142. The status determination unit 143 may determine the type of aquatic organism sucked in through the opening 126. The status determination unit 143 may determine the size of the aquatic organism sucked in through the opening 126. The status determination unit 143 may determine the number of aquatic organisms sucked in through the opening 126. The status determination unit 143 may output the determination result. For example, if the pressure regulator 140 has a display, the status determination unit 143 displays and outputs the determination result on the display of the pressure regulator 140. For example, the status determination unit 143 transmits the determination result to a communication terminal or the like of the user of the feeder 100. This makes it easier to understand the type, size, number, etc. of aquatic organisms sucked in for landing.

[0061] The pressure adjustment unit 141 and the situation determination unit 143 may automatically land only the required amount of aquatic organisms in accordance with the settings made by the setting unit 144. For example, the setting unit 144 sets the total amount of aquatic organisms to be landed. Then, the pressure adjustment unit 141 performs suction of the aquatic organisms, and the situation determination unit 143 determines the amount of aquatic organisms that has actually been sucked in through the opening 126. When the amount of aquatic organisms determined by the situation determination unit 143 reaches the amount set by the setting unit 144, the pressure adjustment unit 141 ends suction. This allows the required amount of aquatic organisms to be landed fully automatically.

[0062] The setting unit 144 may set the amount of aquatic organisms to be landed for each type of aquatic organism to be landed. In this case, the pressure adjustment unit 141 performs suction of the aquatic organisms, and the status determination unit 143 determines the amount of aquatic organisms actually sucked through the opening 126 for each type of aquatic organism. When the amount of aquatic organisms determined by the status determination unit 143 for all types of aquatic organisms to be landed reaches the amount set by the setting unit 144, the pressure adjustment unit 141 ends suction. This allows the required amount of each of multiple types of aquatic organisms to be landed to be fully automated. Note that the pressure adjustment unit 141 may control the suction of aquatic organisms according to the landing status of each of the multiple types of aquatic organisms to be landed. The pressure adjustment unit 141 may not land aquatic organisms to be landed that have already been landed in the amount set by the setting unit 144. The pressure adjustment unit 141 may also be configured to suck in only aquatic organisms to be landed that have not yet been landed.

[0063] The setting unit 144 may set the amount of aquatic organisms to be landed for each size of the aquatic organism to be landed. In this case, the pressure adjustment unit 141 performs suction of the aquatic organisms, and the status determination unit 143 determines the amount of aquatic organisms actually sucked through the opening 126 for each size of the aquatic organism. When the amount of aquatic organisms determined by the status determination unit 143 for all sizes of the aquatic organisms to be landed reaches the amount set by the setting unit 144, the pressure adjustment unit 141 ends suction. This allows the required amount of aquatic organisms of each size to be landed to be fully automated. Note that the pressure adjustment unit 141 may control the suction of aquatic organisms according to the landing status of each of the multiple sizes of aquatic organisms to be landed. The pressure adjustment unit 141 may not land aquatic organisms of a size that have already been landed in the amount set by the setting unit 144 among the aquatic organisms to be landed. The pressure adjustment unit 141 may also be configured to suck in only aquatic organisms of a size that have not yet been landed among the aquatic organisms to be landed.

[0064] The setting unit 144 may set the amount of aquatic organisms to be landed for each type and size of the aquatic organism to be landed. In this case, the pressure adjustment unit 141 performs suction of the aquatic organisms, and the status determination unit 143 determines the amount of aquatic organisms actually sucked through the opening 126 for each type and size of aquatic organism. When the amount of aquatic organisms determined by the status determination unit 143 for all types and sizes of the aquatic organisms to be landed reaches the amount set by the setting unit 144, the pressure adjustment unit 141 ends suction.

[0065] The situation determination unit 143 may determine that an object to be cleaned is located near the opening 126, and the pressure adjustment unit 141 may perform suction in response to the situation determination unit 143 determining that an object to be cleaned is located near the opening 126. Examples of the object to be cleaned include dead aquatic organisms and garbage. For example, the pressure adjustment unit 141 performs suction when it determines that an object to be cleaned is located near the opening 126 while neither suctioning nor landing an aquatic organism is being performed. This can contribute to maintaining a clean underwater environment.

[0066] When a prohibited object that is prohibited from being sucked is located around opening 126, pressure adjustment unit 141 may apply pressure toward opening 126. This makes it possible to keep the prohibited object away from opening 126, thereby reducing the possibility of accidentally sucking up the prohibited object when performing suction. Examples of prohibited objects include aquatic organisms other than the object to be sucked when the object to be sucked has been specified, and objects other than aquatic organisms such as nets.

[0067] 7 may further include a switch 160, and pressure adjuster 140 may further include a switching control unit 145. In this case, pressure adjuster 171 performs suction when switcher 160 has not inserted plate-like member 162 into tubular portion 122.

[0068] Figure 8 shows a schematic diagram of one example of the configuration of feeder 100. Here, differences from Figure 3 will be mainly explained. Feeder 100 shown in Figure 8 includes pressure regulator 170 capable of generating suction pressure, which can be replaced with pressure regulator 140 capable of generating pressing pressure. Pressure regulator 170 includes pressure adjustment unit 171 and opening / closing control unit 176.

[0069] By providing feeder 100 with this configuration, it is possible to feed aquatic organisms and land them by simply replacing pressure regulator 140 and pressure regulator 170. In other words, it is possible to use tubular member 120 for both feeding and landing, thereby increasing the efficiency of the equipment.

[0070] Feeder 100 shown in FIG. 8 may further include camera 150 shown in FIG. 4, and pressure regulator 170 may include image acquisition unit 172, situation determination unit 173, and setting unit 174, which have the same functions as image acquisition unit 142, situation determination unit 143, and setting unit 144. Situation determination unit 173 determines the situation around opening 126 by analyzing the captured image acquired by image acquisition unit 172. Pressure adjustment unit 171 may perform suction based on the determination result by situation determination unit 173.

[0071] Pressure adjustment unit 171 may perform suction when an aquatic organism is present around opening 126. Pressure adjustment unit 171 may not perform suction when no aquatic organism is present around opening 126, and may perform suction when an aquatic organism is present around opening 126.

[0072] The pressure adjustment unit 171 may perform suction when an aquatic organism to be sucked is located around the opening 126. The aquatic organism to be sucked may be an aquatic organism of a type that has been preset as an organism to be sucked by the setting unit 174. The aquatic organism to be sucked may be an aquatic organism of a size that has been preset as an organism to be sucked by the setting unit 174. The aquatic organism to be sucked may be an aquatic organism of a type and size that have been preset as organisms to be sucked by the setting unit 174. The pressure adjustment unit 171 may perform suction only when an aquatic organism to be sucked is located around the opening 126.

[0073] The pressure adjusting unit 171 may perform suction when the aquatic organism is moving toward the opening 126. This can improve the efficiency of suction. The pressure adjusting unit 171 may not perform suction when the aquatic organism is moving away from the opening 126 or when the aquatic organism is facing away from the opening 126. This can reduce the suction force required for suction, reduce energy consumption, and prevent damage to the aquatic organism.

[0074] The pressure adjusting unit 171 may perform suction when the number of aquatic organisms around the opening 126 is greater than the number preset by the setting unit 174. The pressure adjusting unit 171 may not perform suction when the number of aquatic organisms around the opening 126 is less than the number preset by the setting unit 174, and may perform suction when the number of aquatic organisms around the opening 126 is greater than the number preset by the setting unit 174.

[0075] The pressure adjusting unit 171 may apply pressure towards the opening 126 when an object that prohibits suction is located around the opening 126 .

[0076] 8 may further include a switch 160, and pressure adjuster 170 may further include a switch control unit 175 that has the same function as switch control unit 145. In this case, pressure adjuster 171 performs suction when switcher 160 has not inserted plate-like member 162 into tubular portion 122.

[0077] Figure 9 shows a schematic diagram of one example of the configuration of a feeder 100. The feeder 100 shown in Figure 9 includes a food receiving part 310, a tubular member 320, and a base 330. The food receiving part 310 is placed above the water, and the tubular member 320 is placed underwater.

[0078] For example, the bait receiving part 310 and the cylindrical member 320 are installed on the base 330, and the base 330 floats on the water, so that the bait receiving part 310 is placed on the water and the cylindrical member 320 is placed underwater. The base 330 may be provided with one or more floats to increase buoyancy.

[0079] The bait receiving portion 310 receives and stores the bait 200. The bait receiving portion 310 may have a receiving opening 319 that receives the bait 200. The receiving opening 319 may be located on the top surface of the bait receiving portion 310, as shown in Fig. 9, or on a side surface thereof.

[0080] The cylindrical member 320 has a hollow cylindrical portion 322, an opening 324 provided at one end of the cylindrical portion 322, and an opening 326 provided at the other end of the cylindrical portion 322. The opening 324 and the bait receiving portion 310 are connected, and the opening 324 receives bait received by the bait receiving portion 310. The opening 326 is disposed in water. The opening 324 may be an example of a first opening. The opening 326 may be an example of a second opening.

[0081] 9, the cylindrical portion 322 may have a structure in which a portion is flexible. The cylindrical portion 322 may have a structure in which the entire portion is flexible, or may have a cylindrical shape in which the entire portion is fixed without having flexibility.

[0082] The bait 200 contained in the bait receiving section 310 is released into the water through the opening 324, the tubular section 322, and the opening 326. Until it reaches the opening 326, the tubular section 322 reduces the dissolution of the bait 200 and prevents the bait 200 from flowing sideways, thereby allowing the bait 200 to reach a predetermined depth.

[0083] The feeder 100 may be configured to change the depth position of the opening 326 in water. For example, the position of the base 330 may be configured to be movable in the vertical direction relative to the food receiving portion 310 and the tubular member 320. This allows the depth of the opening 326 to be made shallower, for example, by moving the position of the base 330 downward. Furthermore, for example, the length of the tubular portion 322 may be adjustable. For example, the tubular portion 322 may have a bellows structure. For example, the tubular portion 322 may have a structure in which multiple tubes are slidably connected. This allows the depth to which the food 200 reaches to be changed as needed.

[0084] 10 shows a schematic diagram of one example of the configuration of feeder 100. Feeder 100 has an opening / closing part 311 disposed between feed receiving part 310 and opening 324. When opening / closing part 311 is opened, food 200 contained in feed receiving part 310 falls into opening 324 and is released into the water via tube part 322 and opening 326.

[0085] The opening / closing unit 311 may be manually openable and closable. The bait receiving unit 310 may include an opening / closing control unit that controls the opening and closing of the opening / closing unit 311, and the opening / closing control unit may open and close the opening / closing unit 311 by electrical control or the like.

[0086] Figure 11 shows a schematic diagram of one example of the configuration of a feeder 100. Here, differences from the feeder 100 shown in Figure 10 will be mainly described. In the example shown in Figure 11, the feeder 100 includes a camera 350, and the feed receiver 310 includes an opening / closing control unit 312, an image acquisition unit 313, a situation determination unit 314, a setting unit 315, and an adjustment unit 316. Note that it is not essential for the feed receiver 310 to include all of these components.

[0087] Camera 350 is disposed on the other end side of tube portion 322, i.e., on the opening 326 side of tube portion 322. Camera 350 captures an image of the periphery of opening 326. Camera 350 may be a camera that captures an image of a limited range. Camera 350 may also be an omnidirectional camera that can capture images in all directions.

[0088] The image acquiring unit 313 acquires the captured image captured by the camera 350. The image acquiring unit 313 may receive the captured image from the camera 350. The bait receiving unit 310 and the camera 350 may be connected by wire or wirelessly.

[0089] The situation determination unit 314 determines the surrounding situation of the opening 326 by analyzing the captured image acquired by the image acquisition unit 313. For example, the situation determination unit 314 determines whether or not there are aquatic organisms around the opening 326. For example, the situation determination unit 314 determines the positions of the aquatic organisms around the opening 326. For example, the situation determination unit 314 determines the number of aquatic organisms around the opening 326. For example, the situation determination unit 314 determines the types of aquatic organisms located around the opening 326.

[0090] The situation determination unit 314 may determine the posture of the aquatic creature around the opening 326. The situation determination unit 314 may determine the movement direction of the aquatic creature around the opening 326. For example, the situation determination unit 314 determines in which direction the fish is moving relative to the opening 326. As a specific example, the situation determination unit 314 determines whether the fish is moving toward or away from the opening 326, or whether it is crossing in front of the opening 326.

[0091] The opening / closing control unit 312 controls the opening / closing of the opening / closing unit 311 based on the determination result by the situation determination unit 314. For example, the opening / closing control unit 312 opens the opening / closing unit 311 while the situation determination unit 314 determines that an aquatic organism is present around the opening 326. This makes it possible to automatically not release the bait 200 when no aquatic organism is present around the opening 326, but to automatically release the bait 200 when an aquatic organism is present around the opening 326.

[0092] The setting unit 315 performs various settings. The setting unit 315 may execute various settings according to instructions from the user of the feeder 100. The setting unit 315 may acquire the user's instructions via, for example, an input device provided in the feed receiving unit 310. The setting unit 315 may receive the user's instructions from, for example, a communication terminal used by the user.

[0093] The opening / closing control unit 312 may control the opening / closing of the opening / closing unit 311 based on the setting by the setting unit 315 and the determination result by the situation determination unit 314. For example, the opening / closing control unit 312 opens the opening / closing unit 311 when the number of aquatic organisms around the opening 326 is greater than a number preset by the setting unit 315. This prevents the release of the bait 200 while the number of aquatic organisms around the opening 126 is less than the set number, and allows the release of the bait 200 when the number of aquatic organisms around the opening 126 is greater than the set number, thereby enabling efficient feeding. For example, the opening / closing control unit 312 opens the opening / closing unit 311 when a type of aquatic organism preset by the setting unit 315 is located around the opening 126. This limits the release of the bait 200 to when the aquatic organism to which the bait 200 is to be fed is located around the opening 126, enabling efficient feeding.

[0094] The adjustment unit 316 adjusts the bait 200 accommodated in the bait receiving unit 310. For example, the adjustment unit 316 adjusts the size of the bait 200. The adjustment unit 316 changes the bait 200 to a desired size by cutting the bait 200. For example, the adjustment unit 316 adjusts the amount of oil in the bait 200. The adjustment unit 316 may adjust the amount of oil in the bait 200 by supplying oil to the bait 200. As a specific example, the adjustment unit 316 supplies oil to the bait 200 by immersing the bait 200 in a layer of oil. The adjustment unit 316 may supply oil to the bait 200 by pouring or spraying oil onto the bait 200.

[0095] The adjusting unit 316 may adjust at least one of the size of the bait and the amount of hot water based on at least one of the type and size of the aquatic organism to be fed, thereby enabling the bait 200 appropriate for the aquatic organism to be fed to be semi-automatically fed.

[0096] The adjustment unit 316 may adjust the size of the bait 200 based on the type of aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data that registers the size of the bait 200 for each type of aquatic organism, and changes the size of the bait 200 contained in the bait receiving unit 310 to a size that corresponds to the type of aquatic organism to which the bait 200 is to be fed.

[0097] The adjustment unit 316 may adjust the amount of oil in the bait 200 based on the type of aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data that registers the amount of oil in the bait 200 for each type of aquatic organism, and adjusts the amount of oil in the bait 200 contained in the bait receiving unit 310 to the amount of oil that corresponds to the type of aquatic organism to which the bait 200 is to be fed.

[0098] The adjustment unit 316 may adjust the size of the bait 200 based on the size of the aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data in which the size of the bait 200 is registered for each size of aquatic organism, and changes the size of the bait 200 contained in the bait receiving unit 310 to a size that corresponds to the size of the aquatic organism to which the bait 200 is to be fed.

[0099] The adjustment unit 316 may adjust the amount of oil in the bait 200 based on the size of the aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data that registers the amount of oil in the bait 200 for each size of aquatic organism, and adjusts the amount of oil in the bait 200 contained in the bait receiving unit 310 to the amount of oil that corresponds to the size of the aquatic organism to which the bait 200 is to be fed.

[0100] The adjustment unit 316 may adjust the size of the bait 200 based on the type and size of the aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data that registers the size of the bait 200 for each combination of the type and size of the aquatic organism, and changes the size of the bait 200 contained in the bait receiving unit 310 to one that corresponds to the type and size of the aquatic organism to which the bait 200 is to be fed.

[0101] The adjustment unit 316 may adjust the amount of oil in the bait 200 based on the type and size of the aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registered data that registers the amount of oil in the bait 200 for each combination of type and size of aquatic organism, and adjusts the amount of oil in the bait 200 contained in the bait receiving unit 310 to the amount of oil that corresponds to the type and size of the aquatic organism to which the bait 200 is to be fed.

[0102] The adjustment unit 316 may adjust the size and amount of oil of the bait 200 based on the type and size of the aquatic organism to which the bait 200 is to be fed. For example, the adjustment unit 316 stores in advance registration data that registers the size and amount of oil of the bait 200 for each combination of type and size of aquatic organism, and adjusts the size and amount of oil of the bait 200 contained in the bait receiving unit 310 to the size and amount of oil that correspond to the type and size of the aquatic organism to which the bait 200 is to be fed.

[0103] The adjustment unit 316 may adjust at least one of the size and the amount of oil in the bait 200 based on the determination result by the situation determination unit 314.

[0104] For example, the adjustment unit 316 adjusts the size of the bait 200 depending on the type of aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the size of the bait 200 depending on the size of the aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the size of the bait 200 depending on the type and size of the aquatic organism located around the opening 326.

[0105] For example, the adjustment unit 316 adjusts the amount of oil in the bait 200 depending on the type of aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the amount of oil in the bait 200 depending on the size of the aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the amount of oil in the bait 200 depending on the type and size of the aquatic organism located around the opening 326.

[0106] For example, the adjustment unit 316 adjusts the size and amount of oil of the bait 200 depending on the type of aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the size and amount of oil of the bait 200 depending on the size of the aquatic organism located around the opening 326. For example, the adjustment unit 316 adjusts the size and amount of oil of the bait 200 depending on the type and size of the aquatic organism located around the opening 326.

[0107] Figures 12 and 13 show a schematic diagram of one example of the configuration of a feeder 100. Here, differences from the feeder 100 shown in Figure 10 will be mainly explained. In the example shown in Figures 12 and 13, the feeder 100 includes a switcher 360, the feed receiver 310 includes a switch control unit 317, and the tube 122 includes an opening 328 and a lid 3282 that closes the opening 328. The opening 328 is located to the side of the tube 322. The opening 328 may be an example of a third opening.

[0108] The switching control unit 317 switches between a state in which the bait 200 is released from the opening 326 and a state in which the bait 200 is released from the opening 328. The switching control unit 317 causes the selector 160 to insert the plate-shaped member 362 into the tube portion 322 and release the closure of the opening 328 by the lid portion 3282, thereby putting the tube portion 322 into a state in which the bait 200 is released from the opening 328. The switching control unit 317 also causes the selector 360 to return the plate-shaped member 362 from the tube portion 122 and cause the lid portion 3282 to close the opening 328, thereby putting the tube portion 322 into a state in which the bait 200 is released from the opening 326.

[0109] By providing the feeder 100 with such a configuration, it is possible to release the bait 200 to a depth corresponding to the opening 326 or to a depth corresponding to the opening 128.

[0110] 12 and 13 show an example in which one opening 328 is provided in the tubular portion 322, but this is not limiting. Multiple openings 328 may be provided at different positions along the length of the tubular portion 322. In this case, the switcher 360 may have plate-like members 362 at positions corresponding to each of the multiple openings 328. By providing the feeder 100 with this configuration, it is possible to selectively release the bait 200 to a depth corresponding to the opening 326 and to a depth corresponding to each of the multiple openings 328.

[0111] 12 and 13 may further include camera 350 as shown in Fig. 11, and feed receiver 310 may include image acquisition unit 313, situation determination unit 314, setting unit 315, and adjustment unit 316. Feeder 100 may include one camera 350 that can capture images of both the periphery of opening 326 and the periphery of opening 328, or may include a camera 350 that captures images of the periphery of opening 326 and a camera 350 that captures images of the periphery of opening 328.

[0112] When the feeder 100 is equipped with a single camera 350 capable of capturing images of both the periphery of the opening 326 and the periphery of the opening 328, the situation determination unit 314 may determine the periphery of the opening 326 and the periphery of the opening 328 by analyzing the captured image acquired by the image acquisition unit 313. The switching control unit 317 may switch between a state in which the bait 200 is released from the opening 326 and a state in which the bait 200 is released from the opening 328 based on the determination result by the situation determination unit 314. For example, when an aquatic organism is located only around either the periphery of the opening 326 or the periphery of the opening 328, the switching control unit 317 sets the state in which the bait 200 is released from the side where the aquatic organism is located, and the opening / closing control unit 312 opens the opening / closing unit 311. For example, the switching control unit 317 compares the number of aquatic organisms located around the opening 326 with the number of aquatic organisms located around the opening 328, and sets the state in which bait 200 is released from the one with the larger number, and the opening / closing control unit 312 opens the opening / closing unit 311.

[0113] When the feeder 100 is equipped with a camera 350 (sometimes referred to as the first camera 350) that captures images of the area around the opening 326 and a camera 350 (sometimes referred to as the second camera 350) that captures images of the area around the opening 328, the situation determination unit 314 may determine the area around the opening 326 by analyzing the image acquired by the image acquisition unit 313 from the first camera 350, and may determine the area around the opening 328 by analyzing the image acquired by the image acquisition unit 313 from the second camera 350.

[0114] Figure 14 shows a schematic diagram of one example of the configuration of a feeder 100. Differences from the feeder 100 shown in Figure 10 will be mainly described here. The feeder 100 may also function as a water-lifting device for lifting aquatic organisms. The feed receiving unit 310 shown in Figure 14 includes a pressure adjusting unit 318.

[0115] The pressure adjusting unit 318 illustrated in Fig. 14 is capable of generating suction pressure. When feeding is performed, the opening / closing control unit 312 opens the opening / closing unit 311, thereby releasing the bait 200 contained in the bait receiving unit 310 through the opening 326. When landing is performed, for example, when no bait 200 is contained in the bait receiving unit 310, the opening / closing control unit 312 opens the opening / closing unit 311, and the pressure adjusting unit 318 generates suction force to suck aquatic organisms through the opening 326. Note that landing may also be performed when bait 200 is contained in the bait receiving unit 310. For example, the bait receiving unit 310 has a storage unit that stores bait 200 and can be opened and closed; when feeding is performed, the storage unit and the opening / closing unit 311 are opened, and the bait 200 is released from the opening 326; when landing is performed, the opening / closing control unit 312 closes the storage unit and opens the opening / closing unit 311, and the pressure adjustment unit 318 generates suction force to suck aquatic organisms through the opening 326.

[0116] 14 may include the camera 350 shown in FIG. 11, and the feed receiving unit 310 may include an image acquisition unit 313, a situation determination unit 314, a setting unit 315, and an adjustment unit 316. The situation determination unit 314 determines the situation around the opening 326 by analyzing the captured image acquired by the image acquisition unit 313. The pressure adjustment unit 318 may perform suction based on the determination result by the situation determination unit 314.

[0117] Pressure adjustment unit 318 may perform suction when an aquatic organism is present around opening 326. Pressure adjustment unit 318 may not perform suction when no aquatic organism is present around opening 326, and may perform suction when an aquatic organism is present around opening 326. This makes it possible to prevent energy from being wasted by performing suction when no aquatic organism is present around opening 326.

[0118] The pressure adjustment unit 318 may perform suction when an aquatic organism to be sucked is located around the opening 326. The aquatic organism to be sucked may be an aquatic organism of a type that has been preset as an organism to be sucked by the setting unit 315. The aquatic organism to be sucked may be an aquatic organism of a size that has been preset as an organism to be sucked by the setting unit 315. The aquatic organism to be sucked may be an aquatic organism of a type and size that have been preset as organisms to be sucked by the setting unit 315. The pressure adjustment unit 318 may perform suction only when an aquatic organism to be sucked is located around the opening 326. This makes it possible to prevent an aquatic organism that is not a target from being accidentally sucked up.

[0119] The pressure adjusting unit 318 may perform suction when the aquatic organism is moving toward the opening 326. This can improve the efficiency of suction. The pressure adjusting unit 318 may not perform suction when the aquatic organism is moving away from the opening 326 or when the aquatic organism is facing away from the opening 326. This can reduce the suction force required for suction, reduce energy consumption, and prevent damage to the aquatic organism.

[0120] The pressure adjusting unit 318 may perform suction when the number of aquatic organisms around the opening 326 is greater than the number preset by the setting unit 315. The pressure adjusting unit 318 may not perform suction when the number of aquatic organisms around the opening 326 is less than the number preset by the setting unit 315, and may perform suction when the number of aquatic organisms around the opening 326 is greater than the number preset by the setting unit 315. This allows for efficient landing of fish.

[0121] Pressure adjustment unit 318 may be capable of generating pressurization, and may apply pressure toward opening 326 when a prohibited object that prohibits suction is located around opening 326. This makes it possible to keep the prohibited object away from opening 326, and reduce the possibility of accidentally sucking up the prohibited object when suction is performed. Examples of prohibited objects include aquatic organisms other than the object to be sucked when the object to be sucked has been specified, and objects other than aquatic organisms such as nets.

[0122] 14 may further include a switcher 360, the feed receiver 310 may further include a switch control unit 317, and the tube portion 322 may further include an opening 328 and a lid portion 3282. In this case, the pressure adjuster 318 performs suction when the switcher 360 has not inserted the plate-shaped member 362 into the tube portion 322 and the lid portion 3282 is closing the opening 328.

[0123] Figure 15 shows a schematic diagram of one example of the configuration of feeder 100. Here, differences from Figure 10 will be mainly explained. Feeder 100 shown in Figure 15 is equipped with pressure regulator 340, which is replaceable with feed receiving part 310 and is capable of generating suction pressure. Pressure regulator 340 is equipped with pressure adjustment part 348.

[0124] The feeder 100 shown in FIG. 15 may be equipped with the camera 350 shown in FIG. 11, and the pressure regulator 340 may be equipped with an image acquisition unit 343, a situation determination unit 344, and a setting unit 345 having the same functions as the image acquisition unit 313, the situation determination unit 314, and the setting unit 315.

[0125] The situation determination section 344 determines the situation around the opening 326 by analyzing the captured image acquired by the image acquisition section 343. The pressure adjustment section 348 may perform suction based on the result of the determination by the situation determination section 344.

[0126] The pressure adjusting unit 348 may perform suction when an aquatic organism is present around the opening 326. The pressure adjusting unit 348 may not perform suction when an aquatic organism is not present around the opening 326, and may perform suction when an aquatic organism is present around the opening 326.

[0127] The pressure adjustment unit 348 may perform suction when an aquatic organism to be sucked is located around the opening 326. The aquatic organism to be sucked may be an aquatic organism of a type that has been preset as an organism to be sucked by the setting unit 345. The aquatic organism to be sucked may be an aquatic organism of a size that has been preset as an organism to be sucked by the setting unit 345. The aquatic organism to be sucked may be an aquatic organism of a type and size that have been preset as organisms to be sucked by the setting unit 345. The pressure adjustment unit 348 may perform suction only when an aquatic organism to be sucked is located around the opening 326.

[0128] The pressure adjusting unit 348 may perform suction when the number of aquatic organisms around the opening 326 is greater than the number preset by the setting unit 345. The pressure adjusting unit 348 may not perform suction when the number of aquatic organisms around the opening 326 is less than the number preset by the setting unit 345, and may perform suction when the number of aquatic organisms around the opening 326 is greater than the number preset by the setting unit 345.

[0129] The pressure adjusting section 348 may apply pressure towards the opening 326 when an object that prohibits suction is located around the opening 326 .

[0130] 16 is a schematic diagram showing an example of the configuration of the water lifting device 400. The water lifting device 400 includes a pressure regulator 410, a cylindrical member 420, a base 430, and a camera 450.

[0131] The pressure regulator 410 is placed on the water, and the tubular member 420 is placed underwater. For example, the pressure regulator 410 and the tubular member 420 are installed on a base 430, and the base 430 floats on the water, so that the pressure regulator 410 is placed on the water and the tubular member 420 is placed underwater. The base 430 may include one or more floats to increase buoyancy.

[0132] The cylindrical member 420 has a hollow cylindrical portion 422, an opening 424 provided at one end of the cylindrical portion 422, and an opening 426 provided at the other end of the cylindrical portion 422. The opening 424 and the pressure regulator 410 are connected to each other. The opening 424 may be an example of a first opening. The opening 426 may be an example of a second opening.

[0133] Camera 450 is disposed on the other end side of tube portion 422, i.e., on the opening 426 side of tube portion 422. Camera 450 captures an image of the periphery of opening 426. Camera 450 may be a camera that captures an image of a limited range. Camera 450 may also be an omnidirectional camera that can capture images in all directions.

[0134] The pressure regulator 410 includes a pressure adjusting unit 412, an image acquiring unit 413, a situation determining unit 414, and a setting unit 415. The pressure adjusting unit 412 generates a suction pressure.

[0135] The image acquisition unit 413 acquires a captured image captured by the camera 450. The image acquisition unit 413 may receive the captured image from the camera 450. The pressure regulator 410 and the camera 450 may be connected by wire or wirelessly.

[0136] The situation determination unit 414 determines the surrounding situation of the opening 426 by analyzing the captured image acquired by the image acquisition unit 413. For example, the situation determination unit 414 determines whether or not there are aquatic organisms around the opening 426. For example, the situation determination unit 414 determines the positions of the aquatic organisms around the opening 426. The situation determination unit 414 may track the aquatic organisms. For example, the situation determination unit 414 determines the number of aquatic organisms around the opening 426. For example, the situation determination unit 414 determines the types of aquatic organisms located around the opening 426.

[0137] The situation determination unit 414 may determine the posture of the aquatic creature around the opening 426. The situation determination unit 414 may determine the movement direction of the aquatic creature around the opening 426. For example, the situation determination unit 414 determines in which direction the fish is moving relative to the opening 426. As a specific example, the situation determination unit 414 determines whether the fish is moving toward or away from the opening 426, or whether it is crossing in front of the opening 426.

[0138] The pressure adjusting unit 412 may perform suction based on the determination result by the situation determining unit 414. The pressure adjusting unit 412 may perform suction when an aquatic organism is present around the opening 426. The pressure adjusting unit 412 may not perform suction when no aquatic organism is present around the opening 426, and may perform suction when an aquatic organism is present around the opening 426. This makes it possible to prevent energy from being wasted by performing suction when no aquatic organism is present around the opening 426.

[0139] The setting unit 415 performs various settings. The setting unit 415 may execute various settings according to instructions from the user of the water lifter 400. The setting unit 415 may acquire instructions from the user via, for example, an input device provided in the pressure regulator 410. The setting unit 415 may receive instructions from the user from, for example, a communication terminal used by the user.

[0140] The pressure adjustment unit 412 may perform suction based on the setting by the setting unit 415 and the determination result by the situation determination unit 414. The pressure adjustment unit 412 may perform suction when an aquatic organism to be sucked is located around the opening 426. The aquatic organism to be sucked may be an aquatic organism of a type that is preset by the setting unit 415 as an organism to be sucked. The aquatic organism to be sucked may be an aquatic organism of a size that is preset by the setting unit 415 as an organism to be sucked. The aquatic organism to be sucked may be an aquatic organism of a type and size that is preset by the setting unit 415 as an organism to be sucked. The pressure adjustment unit 412 may perform suction only when an aquatic organism to be sucked is located around the opening 426. This makes it possible to prevent an aquatic organism that is not a target from being sucked by mistake.

[0141] The pressure adjusting unit 412 may perform suction when the aquatic organism is moving toward the opening 426. This can improve the efficiency of suction. The pressure adjusting unit 412 may not perform suction when the aquatic organism is moving away from the opening 426 or when the aquatic organism is facing away from the opening 426. This can reduce the suction force required for suction, reduce energy consumption, and prevent damage to the aquatic organism.

[0142] The pressure adjusting unit 412 may perform suction when the number of aquatic organisms around the opening 426 is greater than the number preset by the setting unit 415. The pressure adjusting unit 412 may not perform suction when the number of aquatic organisms around the opening 426 is less than the number preset by the setting unit 415, and may perform suction when the number of aquatic organisms around the opening 426 is greater than the number preset by the setting unit 415. This allows for efficient landing of the aquatic organisms.

[0143] The situation determination unit 414 may determine the suction situation of the aquatic organisms, similar to the situation determination unit 143. The situation determination unit 414 may determine the type of aquatic organism sucked in through the opening 126. The situation determination unit 414 may determine the size of the aquatic organism sucked in through the opening 126. The situation determination unit 414 may determine the number of aquatic organisms sucked in through the opening 126. Similar to the situation determination unit 143, the situation determination unit 414 may output the determination result.

[0144] As with the pressure adjusting unit 141 and the situation determining unit 143, the pressure adjusting unit 412 and the situation determining unit 414 may automatically land only the necessary amount of aquatic organisms in accordance with the settings made by the setting unit 415.

[0145] The situation determination unit 414 may determine that an object to be cleaned is located around the opening 126, similar to the situation determination unit 143, and the pressure adjustment unit 412 may perform suction in response to the situation determination unit 414 determining that an object to be cleaned is located around the opening 126, similar to the pressure adjustment unit 141.

[0146] The pressure adjusting unit 412 may apply pressure towards the opening 426 when a prohibited object that is prohibited from being sucked is located around the opening 426. This makes it possible to keep the prohibited object away from the opening 426, thereby reducing the possibility of accidentally sucking up the prohibited object when performing suction. Examples of prohibited objects include aquatic organisms other than the object to be sucked when the object to be sucked has been specified, and objects other than aquatic organisms such as nets.

[0147] 17 schematically shows an example of the hardware configuration of a computer 1200 that functions as a controller in the pressure regulator 140 or a controller in the feed receiving unit 310. A program installed on the computer 1200 can cause the computer 1200 to function as one or more "units" of the apparatus according to the present embodiment, or can cause the computer 1200 to perform operations associated with the apparatus according to the present embodiment or one or more "units," and / or can cause the computer 1200 to perform a process according to the present embodiment or steps of the process. Such a program can be executed by the CPU 1212 to cause the computer 1200 to perform specific operations associated with some or all of the blocks in the flowcharts and block diagrams described herein.

[0148] The computer 1200 according to this embodiment includes a CPU 1212, a RAM 1214, and a graphics controller 1216, which are interconnected by a host controller 1210. The computer 1200 also includes input / output units such as a communications interface 1222, a storage device 1224, a DVD drive, and an IC card drive, which are connected to the host controller 1210 via an input / output controller 1220. The DVD drive may be a DVD-ROM drive, a DVD-RAM drive, or the like. The storage device 1224 may be a hard disk drive, a solid-state drive, or the like. The computer 1200 also includes a ROM 1230 and legacy input / output units such as a keyboard, which are connected to the input / output controller 1220 via an input / output chip 1240.

[0149] The CPU 1212 operates according to programs stored in the ROM 1230 and RAM 1214, thereby controlling each unit. The graphics controller 1216 acquires image data created by the CPU 1212 into a frame buffer or the like provided in the RAM 1214 or into the graphics controller itself, and causes the image data to be displayed on the display device 1218.

[0150] The communication interface 1222 communicates with other electronic devices via a network. The storage device 1224 stores programs and data used by the CPU 1212 in the computer 1200. The DVD drive reads programs or data from a DVD-ROM or the like and provides them to the storage device 1224. The IC card drive reads programs and data from an IC card and / or writes programs and data to an IC card.

[0151] The ROM 1230 stores therein a boot program or the like that is executed by the computer 1200 upon activation, and / or programs that depend on the hardware of the computer 1200. The input / output chip 1240 may also connect various input / output units to the input / output controller 1220 via a USB port, a parallel port, a serial port, a keyboard port, a mouse port, etc.

[0152] The programs are provided by a computer-readable storage medium such as a DVD-ROM or an IC card. The programs are read from the computer-readable storage medium, installed in the storage device 1224, RAM 1214, or ROM 1230, which are also examples of computer-readable storage media, and executed by the CPU 1212. Information processing described in these programs is read by the computer 1200, and causes cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be configured by implementing operations or processing of information in accordance with the use of the computer 1200.

[0153] For example, when communication is performed between the computer 1200 and an external device, the CPU 1212 may execute a communication program loaded into the RAM 1214 and instruct the communication interface 1222 to perform communication processing based on the processing described in the communication program. Under the control of the CPU 1212, the communication interface 1222 reads transmission data stored in a transmission buffer area provided in the RAM 1214, the storage device 1224, a DVD-ROM, or a recording medium such as an IC card, and transmits the read transmission data to the network, or writes reception data received from the network to a reception buffer area or the like provided on the recording medium.

[0154] Furthermore, the CPU 1212 may cause all or a necessary portion of a file or database stored in an external recording medium such as the storage device 1224, a DVD drive (DVD-ROM), an IC card, etc. to be read into the RAM 1214, and may perform various types of processing on the data on the RAM 1214. The CPU 1212 may then write back the processed data to the external recording medium.

[0155] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and may undergo information processing. The CPU 1212 may perform various types of processing on data read from the RAM 1214, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described throughout this disclosure and specified by the instruction sequences of the programs, and write the results back to the RAM 1214. The CPU 1212 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries, each having an attribute value of a first attribute associated with an attribute value of a second attribute, are stored on the recording medium, the CPU 1212 may search for an entry whose attribute value of the first attribute matches a specified condition from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0156] The above-described programs or software modules may be stored in a computer-readable storage medium on or near the computer 1200. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can also be used as a computer-readable storage medium, thereby providing the programs to the computer 1200 via the network.

[0157] The blocks in the flowcharts and block diagrams in the present embodiments may represent stages of a process in which an operation is performed or "parts" of an apparatus responsible for performing the operation. Particular stages and "parts" may be implemented by dedicated circuitry, programmable circuitry provided with computer-readable instructions stored on a computer-readable storage medium, and / or a processor provided with computer-readable instructions stored on a computer-readable storage medium. The dedicated circuitry may include digital and / or analog hardware circuits, including integrated circuits (ICs) and / or discrete circuits. The programmable circuitry may include reconfigurable hardware circuits, such as field programmable gate arrays (FPGAs) and programmable logic arrays (PLAs), including AND, OR, XOR, NAND, NOR, and other logical operations, flip-flops, registers, and memory elements.

[0158] A computer-readable storage medium may include any tangible device capable of storing instructions that are executed by an appropriate device, such that a computer-readable storage medium having instructions stored thereon comprises an article of manufacture, including instructions that can be executed to create means for performing the operations specified in the flowcharts or block diagrams. Examples of computer-readable storage media may include electronic storage media, magnetic storage media, optical storage media, electromagnetic storage media, semiconductor storage media, etc. More specific examples of computer-readable storage media may include floppy disks, diskettes, hard disks, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), electrically erasable programmable read-only memory (EEPROM), static random access memory (SRAM), compact disc read-only memory (CD-ROM), digital versatile disc (DVD), Blu-ray disc, memory stick, integrated circuit card, etc.

[0159] The computer readable instructions may include either assembler instructions, instruction set architecture (ISA) instructions, machine instructions, machine-dependent instructions, microcode, firmware instructions, state-setting data, or source or object code written in any combination of one or more programming languages, including object-oriented programming languages ​​such as Smalltalk®, JAVA®, C++, etc., and conventional procedural programming languages ​​such as the “C” programming language or similar programming languages.

[0160] The computer-readable instructions may be provided to a general-purpose computer, a special-purpose computer, or another programmable data processing device processor or programmable circuit, either locally or via a local area network (LAN) or a wide area network (WAN) such as the Internet, so that the processor or programmable circuit of the programmable data processing device, such as a computer, executes the computer-readable instructions to create means for performing the operations specified in the flowcharts or block diagrams. Here, the computer may be a personal computer (PC), a tablet computer, a smartphone, a workstation, a server computer, a general-purpose computer, a special-purpose computer, or the like, or may be a computer system in which multiple computers are connected. Such a computer system in which multiple computers are connected is also called a distributed computing system, and is a broad definition of computers. In a distributed computing system, multiple computers collectively execute a program by each executing a portion of the program and passing data between computers as needed during program execution.

[0161] Examples of processors include computer processors, central processing units, processing units, microprocessors, digital signal processors, controllers, microcontrollers, etc. A computer may have one or more processors. In a multiprocessor system with multiple processors, each processor executes a portion of a program and passes data between processors as needed during program execution, allowing the multiple processors to collectively execute the program. For example, in multitasking, each of the multiple processors may execute a portion of each task in small chunks by switching tasks at time slice intervals. In this case, which portion of a program each processor executes changes dynamically. Which portion of a program each of the multiple processors executes may also be statically determined by multiprocessor-aware programming.

[0162] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention.

[0163] It should be noted that the execution order of each process, such as operations, procedures, steps, and stages, in the devices, systems, programs, and methods shown in the claims, specifications, and drawings is not specifically stated as "before," "prior to," etc., and that the processes can be performed in any order unless the output of a previous process is used in a later process. Even if the operational flow in the claims, specifications, and drawings is described using "first," "next," etc. for convenience, this does not mean that the processes must be performed in this order.
