Description

Technical Field

[0001] The invention relates to the technical field of giant spiny loach cultivation, in particular to a method for accelerating the maturation of giant spiny loach broodstock. Background Art

[0002] The giant spiny loach, commonly known as the knife loach, inhabits gravelly-bottomed rivers and streams, often hiding in crevices or caves. It feeds on small invertebrates and some plants. It has a slender body, golden yellow above and dark brown below, with two rows of oval patches on its underside. Its anal, dorsal, and caudal fins are connected at the rear. It grows more slowly than other fish, reaching a maximum weight of 1 kg. It grows fastest when water temperatures are between 20 and 28°C; growth slows as temperatures rise or fall. When water temperatures drop below 15°C, it barely feeds and essentially stops growing. During the cold winter months, it completely stops growing and hibernates in caves or burrows into mud. Males are typically more than twice as heavy as females of the same age, and can reach a maximum length of 90 cm.

[0003] At present, the maturation of giant spiny loach broodstock needs to be carried out in a specific incubator. A qualified incubator needs to be basically equipped with a microporous oxygenation disk and a heating rod. However, in the existing technology, the oxygenation disk and the heating rod are only fixedly placed in a certain area of ​​the incubator, which cannot simulate the natural growth of giant spiny loach in a stream environment, resulting in poor mobility of giant spiny loach in the incubator, causing the maturation-promoting drugs to be unable to be fully and effectively absorbed by the giant spiny loach, resulting in a low hatching rate of its fertilized eggs. The water quality in the incubator is crucial to the maturation process of giant spiny loach. Impurities in the water and feces on the bottom of the water need to be treated in time to ensure that the broodstock maturation process of giant spiny loach is completed quickly and efficiently. Therefore, the present invention proposes a cultivation method for maturation of giant spiny loach broodstock. Summary of the Invention

At the same time, the guide plate drives a T-shaped transmission shaft to reciprocate left and right, and the T-shaped transmission shaft drives a conical stirring rod to rotate. The conical stirring rod rotates and stirs to discharge feces and impurities in the gaps of the sterilized volcanic stones, and then flows downward by the traction of the guide plate, thereby preventing the feces and impurities from being inside the sterilized volcanic stones for a long time and thus damaging the overall water quality in the cultivation room.

[0021] The present invention controls the movement of the magnetic transmission shaft by the up and down movement of the water pump, and controls the rotation of the transmission material changing shaft by the movement of the magnetic transmission shaft. The rotation of the transmission material changing shaft automatically switches the filter cotton through the clamping claws, thereby improving the practicality of the present invention and reducing the impact of noise generated during manual replacement on the foraging of the giant loach.

DETAILED DESCRIPTION

[0039] In the prior art, the oxygenating disk and the heating rod are fixedly placed in a certain area of ​​the incubator, which cannot simulate the natural growth of the giant spiny loach in a stream environment. As a result, the giant spiny loach has poor mobility in the incubator, and the maturation-promoting drugs cannot be fully and effectively absorbed by the giant spiny loach, resulting in a low hatching rate of its fertilized eggs. In addition, impurities in the water and feces on the bottom of the water need to be processed in a timely manner to ensure that the broodstock maturation process of the giant spiny loach is completed quickly and efficiently.

When the contraction tube 11 is contracted, the internal air retention time is short, and the water temperature discharged from the extrusion tube 13 is appropriately increased, which promotes the feeding desire of the big spiny loach.

[0048] In order to replace the filter cotton in time, the replacement component 300 includes a magnetic transmission shaft 301, which is slidingly connected to the incubation chamber 1, and the surface of the magnetic transmission shaft 301 is meshed with a mating gear 302, and the surface of the mating gear 302 is meshed with a transmission gear 303, and the surface of the transmission gear 303 is fixedly connected to a transmission material changing shaft 304, which is placed inside the storage tube 4, and the transmission material changing shaft 304 is rotatably connected to the storage tube 4, and the surface of the transmission material changing shaft 304 is fixedly connected to a clamping claw 305.

[0049] In order to facilitate the automatic feeding of the giant loach, the feeding assembly 400 includes a float 401, a slide rod 402 is movably connected above the float 401, the slide rod 402 is slidably connected to the feeding chamber 7, a return spring 405 is fixedly connected above the slide rod 402, and one end of the moving rod 403 is rotatably connected to the surface of the slide rod 402, and the other end of the moving rod 403 is rotatably connected to the lower material piece 404, and the lower material piece 404 is rotatably connected to the feeding chamber 7.

The air duct 10 is slidably connected above the contraction tube 11, and the air duct 10 is fixedly connected to the heater 3.

[0051] Sterilized volcanic stones 19 are placed above the supporting plate 6, and the conical stirring rod 107 is placed inside the sterilized volcanic stones 19; a transition plate 20 is provided inside the cultivation chamber 1 below the feeding chamber 7, and a material blocking slope 17 is provided on the surface of the transition plate 20. Sterilized fine sand 18 is placed on the left side of the material blocking slope 17, and a rubber plate 21 is provided on the surface of the transition plate 20 below the sterilized fine sand 18.

[0052] Working Principle: The device is placed in the laboratory. Stronger spiny loaches are selected and placed in the incubation room 1. When the spiny loaches adapt to the incubation method of the device, they are injected with oxytocin drugs. The oxytocin drugs use human chorionic gonadotropin (HCG9) or luteinizing hormone-releasing hormone analog (LHRH-A). The drugs are diluted and dissolved with normal saline before use. The injection dose is calculated based on 0.5 ml / kg of the broodstock body weight. The injection site is the back muscle. The injection method uses a two-injection method. The first injection dose is 1 / 5 of the total dose, and the second injection is the remaining dose. The interval is 24 hours. The dose for male fish is halved. When the water temperature is 20℃-25℃, the effect lasts for 36-48 hours.

[0053] The cultivation chamber 1 of the device has a water depth of 0.8m-1.0m and uses flowing and still water for aeration. Daily water filtration and replacement of 20%-50% is carried out. The dissolved oxygen (DO) in the water is no less than 6mg / L, the pH is 7-8, and the transparency is 40cm-50cm. The water in the cultivation chamber is filtered, disinfected, and exposed to sunlight to achieve clarity, free of impurities and suspended matter, with a DO of no less than 6mg / L and a water temperature of 26°C-28°C.

[0054] The device drives the screw rod 103 to rotate through the servo motor 2, and the rotation of the screw rod 103 drives the water pump 9 to perform lifting work, the screw rod 103 drives the transmission rod 102 to rotate, and the transmission rod 102 drives the driving disk 104 to rotate, and the rotation of the driving disk 104 drives the guide plate 105 to attract the sewage under the cultivation chamber, and the rotation of the driving disk 104 drives the T-shaped transmission shaft 106 to slide, and the sliding of the T-shaped transmission shaft 106 drives the conical stirring rod 107 to rotate, and the rotation of the conical stirring rod 107 stirs the feces in the gaps of the sterilized volcanic stones 19, and the feces and impurities in the water are collected by the filter assembly 200, and the filter cotton 203 in the filter assembly 200 is automatically replaced by the replacement assembly 300;

[0055] The lifting of the water pump 9 drives the fixed rod 15, the extrusion tube 13 and the filter chamber 14 to move synchronously. The lifting of the fixed rod 15 drives the shading plate 8 to slide on the upper surface of the feeding chamber 7 through the connecting rod 16. The function of the shading plate 8 is to simulate shading for the cultivation chamber 1. The movement of the shading plate 8 is to change the shaded area. The rising of the water pump 9 controls the shading plate 8 to slide to the right to shade the large spiny loach in the foraging state, thereby reducing the influence of light on the large spiny loach when foraging. The up and down sliding of the extrusion tube 13 controls the change of water flow in the cultivation chamber 1, and the movement of the filter chamber 14 is used to control the replacement of the filter cotton 203.

[0056] like Figure 11 As shown in the figure, the state is the initial state of the device, wherein the water inside the cultivation chamber 1 is clear, free of impurities and suspended matter, the inside of the filter cotton 203 is free of feces and pollutants, the sterilized fine sand 18 and the sterilized volcanic stone 19 are relatively flat and have no protrusions, and the horizontal surface is slightly higher than the transition plate 20. As shown in the figure, the direction of the arrow represents the direction of water flow, and the size of the arrow represents the size of the water flow in this area. Figure 12 、 Figure 13 、 Figure 14 Similarly, at this time, the water flow inside the culture chamber 1 is strong, simulating the flow of streams in the natural environment, improving the activity of the giant loach, promoting the giant loach's foraging and digestion, and strengthening the giant loach's physique;

[0057] Start the water pump 9, which is a three-in-one filter integrating oxygenation, filtration and wave making. The water inside the cultivation chamber 1 is absorbed by the water pump 9 and then discharged through the extrusion tube 13. Filter cotton 203 is placed inside the filter chamber 14. The filter cotton 203 absorbs and filters impurities in the water. The flow rate of water discharged from the extrusion tube 13 is affected by the impurities adsorbed on the surface of the filter cotton 203. The more impurities, the slower the flow rate. The slower the flow rate, the smaller the fluctuation of the water. A contraction tube 11 is installed at the connection between the extrusion tube 13 and the water pump 9. When the water flows through the contraction tube 11 quickly, the surrounding pressure will become smaller, thereby generating negative pressure, sucking air into the extrusion tube 13, and the extrusion tube 13 discharges a mixture of water and air, speeding up the cultivation. The water in the chamber 1 is oxygenated while flowing. A heater 3 is provided above the contractile tube 11. The function of the heater 3 is to heat the air to adjust the water temperature. The power and temperature control of the heater 3 can be adjusted according to the water temperature of the laboratory and the water in the cultivation chamber 1. That is, the mixture discharged from the extrusion tube 13 can control the water temperature inside the cultivation chamber 1 while creating waves and increasing oxygen. The water temperature of the water discharged from the extrusion tube 13 is appropriately adjusted by the residence time or transportation distance of the air inside the contractile tube 11 and the air duct 10. Compared with the heating method using a heating rod in the prior art, the device can automatically adjust the temperature difference at different water levels, and timely track the temperature of the area at different depths according to the activity of the giant loach.

[0058] according to Figure 12 As shown, after the spiny loach is cultivated in the device for a certain period of time, the feces and impurities in the water produced are gradually absorbed by the filter cotton 203. Since the water pump 9 is blocked by impurities on the surface of the filter cotton 203 during the water pumping process, the water flow rate caused by the extrusion tube 13 gradually decreases, reducing the activity of the spiny loach. Because the food in the stomach of the spiny loach has been completely digested and excreted from the body during this period, it affects the water quality inside the cultivation chamber 1. Reducing the activity of the spiny loach is to reduce the contact between the spiny loach and impurities, so as to prevent the spiny loach from getting sick and dying after absorbing too many impurities.

[0059] When feeding the big spiny loach, the servo motor 2 is started, and the screw 103 rotates to drive the water pump 9 to rise, and the water pump 9 drives the filter chamber 14 to rise synchronously. A magnetic block is installed on the surface of the water pump 9. During the upward movement of the water pump 9, the magnetic block drives the magnetic transmission shaft 301 to move upward by attraction. The upward movement of the magnetic transmission shaft 301 drives the matching gear 302 to rotate, and the matching gear 302 drives the transmission change shaft 304 to rotate through the transmission gear 303. At this time, the loading plate 201 is limited by the cultivation chamber 1, and the filter chamber 14 continues to move upward. Therefore, the limiting arc plate 204 slides out of the filter chamber 14, and the limiting arc plate 204 brings out the filter cotton 203 inside it, and the filter cotton 203 is exposed at the interface between the storage tube 4 and the cultivation chamber 1. At the same time, the transmission material changing shaft 304 drives the plurality of clamping claws 305 to rotate and pull the exposed filter cotton 203 downward, and the new filter cotton 203 inside the storage tube 4 is transported to the inside of the limiting arc plate 204. At this time, the spring 205 is in a compressed state. When the water pump 9 moves downward, the spring 205 pushes the loading plate 201 to reset;

[0060] When the screw rod 103 rotates and drives the transmission rod 102 to rotate, a belt is installed between the transmission rod 102 and the driving disc 104, and the transmission rod 102 drives the driving disc 104 to rotate. The driving disc 104 rotates and drives the guide piece 105 to swing left and right through the guide block 108. There are multiple sets of one-way pieces on the surface of the guide piece 105. When the guide piece 105 moves to the left, the one-way piece is closed. Therefore, the guide piece 105 attracts the water above the supporting plate 6 to the bottom of the supporting plate 6, and the water above the supporting plate 6 is sucked into the water below the supporting plate 6. Impurities in the water are transported downward. When the guide piece 105 moves to the right, the one-way piece opens. At this time, the water around the carrier plate 6 does not change, reducing the backflow of impurities. The guide piece 105 drives the T-type transmission shaft 106 to slide left and right. The left and right sliding of the T-type transmission shaft 106 drives the conical stirring rod 107 engaged with the T-type transmission shaft (106) to rotate. Through the stirring of several groups of conical stirring rods 107, the feces and impurities in the gaps of the sterilized volcanic stone 19 are discharged to the surface in time.

[0061] Since the filter cotton 203 is automatically replaced during the upward movement of the water pump 9, the water flow rate drawn out by the water pump 9 reaches a maximum at this time. At the same time, since the extrusion tube 13 is above the water level, the water discharged from the extrusion tube 13 is not affected by the pressure of the water inside the cultivation chamber 1, resulting in an increase in the flow rate of the water discharged at this time. Figure 13 As shown, since the water discharged from the extrusion tube 13 is blocked by the material blocking slope 17, the water level on the left side of the material blocking slope 17 rises, and the rising water level drives the float 401 to rise, and the rising float 401 drives the slide bar 402 to rise synchronously, and the rising slide bar 402 drives the lower material piece 404 to rotate through the motion rod 403, and the rotation of the lower material piece 404 releases the large spiny loach food inside it;

[0062] As the water flow velocity above the transition plate 20 increases at this time, the big spiny loach swims upward to the top of the transition plate 20 under the influence of the water flow. Due to the water level difference on the left and right sides of the blocking slope 17, the water on the left side is pulled to the right side of the blocking slope 17 by the blocking slope 17, generating a vortex. Figure 13 As shown in point a, when the food passes through the vortex, it will continue to move according to the water flow in the vortex, simulating the swimming posture of aquatic animals in the stream, enhancing the giant loach's desire to attack the food and increasing its enthusiasm for foraging.

[0063] Under the impact of water flow on the sterilized fine sand 18, the sterilized fine sand 18 changes from a flat state to a state with the left side low and the right side high. Figure 14 As shown, at this time, the water level below the float 401 drops, and the lower material piece 404 is reset and closed to no longer feed the big spiny loach. At this time, since the horizontal surface on the right side of the sterilized fine sand 18 is raised, the horizontal surface on the right side of the blocking slope 17 will be raised accordingly, and the water on the right side of the blocking slope 17 reduces the obstruction of the blocking slope 17 to it. At this time, the water flow rate on the right side of the blocking slope 17 is too large. After foraging, the big spiny loach cannot adapt to the excessively large water flow and swims to the bottom of the transition plate 20. The sterilized fine sand 18 is impacted by the water flow below the rubber plate 21 in the later stage and gradually returns to a flat state from the state of low on the left and high on the right. Figure 15 As shown;

[0064] When the big spiny loach swims to the top of the sterilized volcanic stone 19, the servo motor 2 is started to drive the water pump 9 to descend. Figure 11 As shown, at this time, the water flow is strong, and the feces stirred by the conical stirring rod 107 will be impacted to the right side of the blocking plate 5, and then filtered by the filter cotton 203, so that the water quality inside the cultivation chamber 1 meets the cultivation standard again.

[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the spirit and scope of the invention, the scope of which is defined by the claims and their equivalents.

Claims

1. A method for accelerating the maturation of giant loach broodstock, characterized in that: The following steps are involved: Step 1: Select strong large spiny loaches and place them in the breeding room; Step 2: The water flow is adjusted by changing the position of the water pump. When the water pump (9) is raised or lowered, the shrink tube (11) fixedly connected to the surface of the water pump (9) will expand and contract inside the air duct (10). When the shrink tube (11) is stretched, the air route blown from the heater (3) into the extrusion tube (13) is extended, and the temperature of the water discharged from the extrusion tube (13) is reduced. When the shrink tube (11) is contracted, the air retention time is shortened, and the temperature of the water discharged is increased. Step 3: Impurities are removed during the movement of the water pump. When the water pump (9) moves, the drive disc (104) rotates, and the guide block (108) on the drive disc (104) drives the guide sheet (105) to slide left and right. The guide sheet (105) is provided with a one-way sheet on its surface. When it moves to the left, it pulls the water containing impurities above the carrier plate (6) to the bottom, and when it moves to the right, it prevents the impurities from flowing back. At the same time, the guide sheet (105) drives the T-type transmission shaft (106) to reciprocate, driving the conical stirring rod (107) engaged with the T-type transmission shaft (106) to rotate, stirring the sterilized volcanic stone (19) above the carrier plate (6), discharging feces and impurities in the gap, and then pulling them to the bottom through the guide sheet (105); Step 4: Switch the filter cotton during the movement of the water pump. During the lifting and moving process of the water pump (9), the magnetic block on the surface of the water pump (9) drives the magnetic transmission shaft (301) to rise and fall synchronously. The magnetic transmission shaft (301) engages and drives the matching gear (302). The matching gear (302) drives the transmission material changing shaft (304) to rotate through the transmission gear (303). The clamping claw (305) on the surface of the transmission material changing shaft (304) pulls out the old filter cotton (203) in the limiting arc plate (204) in the filter assembly (200) and transports the new filter cotton (203) in the storage tube (4) into the limiting arc plate (204). The switching of the filter cotton (203) is completed. When the water pump (9) descends, the spring (205) on the surface of the limiting column (202) in the filter assembly (200) pushes the loading plate (201) to reset.

When the contraction tube (11) is stretched, the air route blown from the heater (3) to the inside of the extrusion tube (13) is extended, and the temperature of the water discharged through the extrusion tube (13) is appropriately reduced. When the contraction tube (11) is contracted, the internal air retention time is short, and the temperature of the water discharged from the extrusion tube (13) is appropriately increased, thereby promoting the feeding desire of the large-spined loach.
