[0028] In order to enable a more complete understanding of the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0030] Reference will now be made to the following description Figures 1 to 4 The fish nest is checked according to the artificial induced spawning of the Acrossocheilus paradoxus provided by some embodiments of the present application.

[0031] Please refer to Figure 1 The fish nest is checked according to the artificial induced spawning of the Acrossocheilus paradoxus provided by some embodiments of the present application, which includes a box 100, a microfluidic assembly 200 and a gravel layer 300. The box 100 has a containing cavity 110, and the box 100 includes at least one inlet and outlet 120. The inlet and outlet 120 are arranged on the side surface of the box 100; the microfluidic assembly 200 is connected with the box 100, and the microfluidic assembly 200 has a microfluidic path extending at least partially through the microfluidic assembly 200, the microfluidic path being in communication with the water area of the containing cavity and being used to form a micro water flow; and the gravel layer 300 is arranged in the containing cavity 110.

[0032] In this embodiment, the box 100 is in the shape of a cuboid, and the length, width, height and thickness of the box can be set according to the behavior habits of the Acrossocheilus paradoxus, so as to provide sufficient activity and spawning space for the Acrossocheilus paradoxus, to form a relatively hidden and quiet place, to attract the Acrossocheilus paradoxus in the spawning period to stay, and to facilitate checking and judging the Acrossocheilus paradoxus with mature gonadal development. The shape of the box 100 can also be adjusted according to the actual use scene, and can be set as a square or a cylinder.

[0033] In this embodiment, the box 100 comprises at least one inlet and outlet 120, the number of which can be one, two or even more, without limitation. The inlet and outlet 120 is arranged on the side surface of the box 100, and the specific position of the inlet and outlet 120 on the side surface of the box 100 can be set according to actual needs. The size of the inlet and outlet 120 can be set according to the size of the body of the golden threadfish, so that the golden threadfish can try to enter and exit. A circle of elastic or flexible material such as rubber or silicone can be arranged or wrapped around the inlet and outlet 120, which can prevent the golden threadfish from being scratched or cut when trying to enter and exit.

[0034] In this embodiment, the micro-flow assembly 200 is connected with the box 100, which can be adsorbed on the side surface of the box 100 by arranging a suction cup on the contact surface of the micro-flow assembly 200 and the box 100, or can be installed by a fixing seat or a fixing support, or can be fixed on the side surface of the box 100 by a buckle or a screw, and the specific connection mode can be selected according to actual needs, without limitation. The micro-flow assembly 200 can be arranged near the inlet and outlet 120 or at other positions, without limitation. The micro-flow assembly 200 has a micro-flow path extending at least partially through the micro-flow assembly 200, and the micro-flow path communicates the water area of the external space with the holding cavity. The micro-flow assembly 200 can transport water from the external space to the holding cavity or from the holding cavity to the external space along the micro-flow path, so as to form a micro-water flow. The micro-water flow can simulate the water flow conditions in the natural breeding environment of the golden threadfish, attracting the golden threadfish in the breeding season to stay. It can be understood that the micro-flow assembly is equipped with an independent power source for driving the water flow.

[0035] In this embodiment, the gravel layer 300 is arranged in the holding cavity 110, and the gravel layer 300 is laid on the bottom of the box 100. The gravel layer 300 can provide a hiding place similar to that in the natural environment for the golden threadfish, and can simulate the natural breeding environment of the golden threadfish to attract the golden threadfish in the breeding season to stay.

[0036] For example, the size of the box 100 can be 50 cm x 40 cm x 30 cm, the diameter of the inlet and outlet 120 can be 3-5 cm, the distance from the center point of the inlet and outlet 120 to the bottom surface of the box 100 can be 15 cm, and the diameter of the gravel can be 3-4 cm.

[0037] In some embodiments, the box 100 comprises a pouring port 131 and a pouring cover plate 132. The pouring port 131 is arranged at the bottom of the box wall of the box 100, and is used for pouring the gravel layer 300 in the holding cavity 110. The pouring cover plate 132 is rotationally connected with the box 100, and is used for opening and closing the pouring port 131.

[0038] In this embodiment, the pouring port 131 is used to pour the gravel layer 300 in the containing cavity 110, avoiding the need for personnel to overturn and pour out the gravel layer 300, reducing the labor intensity of personnel, and making the cleaning of the fish nest more convenient. The size of the pouring port 131 can be set according to the size of the gravel, so that the gravel layer 300 can be smoothly poured out. The pouring cover plate 132 is rotatably connected to the box body 100 on one side, which can be connected by means such as hinges, hinges or pin shafts, and the remaining sides can be fixed with the box body 100. When the box body 100 is poured, the pouring cover plate 132 can be pushed open outward by the gravel layer 300 under the action of gravity, thereby pouring out the gravel layer 300. It can be understood that the remaining side of the pouring cover plate 132 can also be fixed with the box body 100 by means of buckles and the like, and then the fixing is released when needed.

[0039] In some embodiments, the bottom of the box body 100 is provided with a plurality of meshes 140.

[0040] In this embodiment, the bottom of the box body 100 is provided with a plurality of meshes 140, which can drain excess water when the fish nest is pulled up, thereby reducing the overall weight of the fish nest and reducing the load on the hoisting equipment or reducing the labor intensity of personnel. The drained fish nest is more convenient for subsequent inspection and artificial insemination of the Oxygobius fulvus, thereby improving work efficiency.

[0041] In some embodiments, the side surface of the box body 100 is provided with a plurality of auxiliary drainage holes 150.

[0042] In this embodiment, the plurality of auxiliary drainage holes 150 on the side surface of the box body 100 can prevent the gravel layer 300 from causing the mesh 140 to drain poorly or the drainage speed to decrease. The mesh 140 and the auxiliary drainage hole 150 can work together to speed up the drainage speed and ensure that the water in the box body 100 can be drained in time. The auxiliary drainage hole 150 can be circular, oval or rectangular, and the plurality of auxiliary drainage holes 150 can be uniformly distributed on the side surface of the box body 100 near the bottom, which can make the drainage process of the box body 100 more stable and uniform.

[0043] In some embodiments, the opposite side surfaces of the box body 100 are provided with at least one pair of lifting lugs 160.

[0044] In this embodiment, the at least one pair of lifting lugs 160 are symmetrically arranged on the opposite side surfaces of the box body 100, so that the center of gravity of the box body 100 can be in a relatively balanced state when the fish nest is pulled up. The material of the lifting lug 160 can be the same as or close to that of the box body 100, so that the lifting lug 160 and the box body 100 can be fixed by welding, or other ways such as bolts can be used. The lifting lug 160 can be used in cooperation with the lifting rope or hook to easily put or pull out the fish nest from the breeding circle barrel or breeding pond.

[0045] In some embodiments, the micro-flow assembly 200 comprises a first opening 210 and a second opening 220, the first opening 210 is in communication with the water area of the external space, and the second opening 220 is in communication with the water area of the accommodation cavity 110; the first opening 210 and the second opening 220 are used to define the starting position of the micro-flow path.

[0046] In this embodiment, a hole can be opened at the position of the micro-flow assembly 200 corresponding to the side surface of the box 100. The second opening 220 is aligned with the hole, and then the micro-flow assembly 200 is connected with the box 100, so that the second opening 220 is located in the accommodation cavity 110, and the first opening 210 is located in the space outside the box 100. The water area of the external space and the accommodation cavity can exchange through the first opening 210 and the second opening 220, and form a micro-water flow. The water exchange of the first opening 210 and the second opening 220 can improve the water quality in the fish nest, and the micro-water flow can simulate the water flow condition in the natural breeding environment of the golden-line barb, which can attract the golden-line barb in the spawning period to stay.

[0047] For example, the micro-flow assembly 200 can be a water pump, and the water inlet and outlet of the water pump can correspond to the first opening 210 and the second opening 220. The first opening 210 and the second opening 220 can be connected to specific positions by connecting corresponding pipelines to change the starting position of the micro-flow path. The micro-water flow can be realized by using a micro water pump, reducing the motor speed of the water pump, or adjusting the cross-sectional area of the first opening 210 or the second opening 220. It can be understood that the micro-flow assembly 200 can be provided with a cover or a pad structure made of silica gel or rubber for shock absorption and sound absorption.

[0048] In some embodiments, the mesh 140 is square.

[0049] In this embodiment, the mesh 140 can be used for drainage. The mesh 140 can be square, or can be rhombus or circular, etc. A plurality of square meshes 140 are arranged in order at the bottom of the box 100, which can be arranged in a rectangular array or a triangular array, etc. The distance between adjacent meshes 140 can be set according to actual needs. The side length of the mesh 140 can be set to be less than 0.5 cm, or can be set according to the size of the gravel. It can be understood that under the premise of ensuring strength and stability, the shape, arrangement mode, arrangement density and size of the mesh, etc. Geometric parameters can be set according to actual needs, which are not limited here.

[0050] In some embodiments, the box 100 is made of stainless steel material.

[0051] In this embodiment, the box 100 is made of stainless steel material. The stainless steel material has high strength, so that the box 100 can withstand certain external pressure, and also improves the stability of the structure of the box 100. At the same time, under most water quality conditions, the box 100 made of stainless steel material is not easy to rust, has strong corrosion resistance, can provide a reliable hiding space for the spawning of the golden-line barb, and can also enhance the durability of the fish nest and reduce the maintenance requirements of the fish nest. It should be understood that, in addition to being made of stainless steel material, the box 100 can also be made of high-strength and corrosion-resistant materials such as aluminum alloy, or can also be coated with high-performance anti-corrosion paint, which is not limited here.

[0052] In some embodiments, the artificial induced spawning nest for the golden-line barb further comprises a box cover 400, which is rotatably connected to the top of the box 100.

[0053] In this embodiment, one side of the box cover 400 is rotatably connected to the box 100, which can be connected by hinges, pins or hinges, etc. The remaining sides of the box cover 400 are not fixed to the box 100, and the flexible turning of the box cover 400 can realize the opening and closing of the box 100. It should be understood that the size of the box cover 400 matches the box 100, and the box cover 400 can be made of high-strength and corrosion-resistant materials such as stainless steel or aluminum alloy, or can also be coated with high-performance anti-corrosion paint, which is not limited here.

[0054] For example, three-quarters of the area of the top of the box 100 is covered by a stainless steel sheet, which is welded to the top of the box 100, and one-quarter of the area of the box 100 is covered by the box cover 400, which is rotatably connected to the top of the box 100.

[0055] In some embodiments, the outer surface of the box cover 400 is provided with a hand-held part 410.

[0056] In this embodiment, the hand-held part 410 is in a semi-ring structure as a whole to facilitate the fingers to pass through and grip. The hand-held part 410 can be arranged at a position away from the position where the box cover 400 is rotatably connected to the box 100 on the outer surface of the box cover 400. The material of the hand-held part 410 can be the same as or close to the material of the box 100, so that the hand-held part 410 and the box 100 can be fixed by welding. The hand-held part 410 can also be made of high-strength rubber or high-strength plastic, and can be fixed by bolts or heat melting. When in use, the box cover can be easily and quickly opened by lifting it slightly upward with the hand-held part 410 as the fulcrum. When closing the box cover 400, the box cover 400 can be aligned and closed with the box 100 more accurately by applying downward pressure through the hand-held part 410.

[0057] It should be noted that the artificial induced ovulation nest of the Cyprinocirrhinus carinatus provided by some embodiments of the present application is generally used in the breeding season of the Cyprinocirrhinus carinatus, and in the morning to early morning period on a sunny day when the water temperature is 21-23°C. This is because the Cyprinocirrhinus carinatus in the estrus period will relatively densely seek a suitable spawning site for mating and spawning. The use process of the nest can include but is not limited to the following steps: opening the box cover 400, laying a layer of gravel on the bottom of the box body 100, and the gravel layer 300 can create a “gravel group” spawning site similar to the natural environment for the Cyprinocirrhinus carinatus. Close the box cover 400, tie the lifting rope on the lifting lug 160, and slowly put the nest into the breeding circle barrel or breeding pool so that the nest sinks to the bottom of the water. The Cyprinocirrhinus carinatus will enter the estrus period after the gonad matures, and the male and female fish will automatically pair and seek a mating and spawning site. The Cyprinocirrhinus carinatus in the estrus period can enter the nest through the inlet and outlet 120. During the peak period of Cyprinocirrhinus carinatus spawning, the nest is regularly (time interval 40-50 minutes) pulled out of the breeding circle barrel or breeding pool to check, and the Cyprinocirrhinus carinatus with mature gonads is taken out, and then artificial insemination and other operations are immediately performed. After the pulled-out nest is checked, the above steps can be repeated to use it again.
