Description

Technical Field

[0001] This utility model relates to the field of river grouper breeding, specifically to a breeding pond for river grouper breeding. Background Technology

[0002] Freshwater grouper are tropical fish that live entirely in freshwater, but can also thrive in seawater with a salinity below 10‰. Their optimal temperature range is 25-30℃. When the water temperature drops to 20℃, their feeding decreases significantly, and when it drops to 15℃, they lose their balance. Therefore, areas where pond water temperatures drop below 15℃ during winter are unsuitable for freshwater grouper growth. During winter, freshwater grouper thrive in water temperatures above 19℃. Freshwater grouper are predominantly carnivorous fish. During the fry stage, their carnivorous characteristics are strong, primarily feeding on zooplankton. In the breeding of stream grouper fry, two methods are commonly used: land cultivation and cement pond cultivation. A search revealed existing technology (publication number: CN202020357460.0) for a fry breeding pond. The text describes a "multi-condition cultivation mechanism 3 including a warm light lamp 31, an air duct 32, an air pump 33, a drain plug 34, a power adjustment switch 35, an air equalization rod 36, a sedimentation tray 37, and a heating pipe 38. The power adjustment switch 35 is installed on the front end of the breeding pond body 1, and the right end of the breeding pond body 1..." Equipped with a drain plug 34, an air pump 33 is installed on the upper right side of the main body 1 of the breeding tank, an air guide pipe 32 is connected to the left side of the air pump 33, an air equalization rod 36 is connected to the lower side of the air guide pipe 32, a sedimentation tray 37 is installed on the lower inside of the main body 1 of the breeding tank, a heating pipe 38 is installed on the lower inside of the main body 1 of the breeding tank, and a warm light 31 is installed on the lower end of the visible box cover 2. This design solves the problem of the original fish fry breeding tank having a single function and poor use effect. However, in the existing technology, the multi-condition breeding mechanism accelerates the growth rate of stream grouper, resulting in greater differences in the growth of individual stream grouper fry in the tank. If the fry are not separated in time, cannibalism is likely to occur. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a breeding pond for river grouper is provided to solve the problem that in existing technologies, multi-condition breeding institutions accelerate the growth rate of river grouper, resulting in greater differences in the growth of individual river grouper fry in the pond, and cannibalism is likely to occur if the fry are not separated in time.

[0004] To achieve the above objectives, a breeding pond for river grouper is provided, comprising: a river grouper breeding pond and a drive frame, wherein the drive frame is snap-fitted and supported on the upper surface of the river grouper breeding pond.

[0005] The inner wall of the pufferfish breeding pond is provided with a water inlet and a water outlet. The drive frame is welded with connecting frames on the front and rear sides. The connecting frames are connected to connecting plates and driving net plates via threaded rods. The driving net plates are symmetrically attached to the inner walls of the left and right sides of the pufferfish breeding pond. The upper end of the connecting frame is connected to a seedling sieve plate via an electric slide. The seedling sieve plate is inserted and distributed at the distance between the two sets of driving net plates. The surface of the seedling sieve plate has screening holes, and the side of the seedling sieve plate is attached with a barrier plate.

[0006] Furthermore, a water-blocking plug is provided on the right end face of the pufferfish breeding pond, and the water inlet and outlet are respectively distributed on the left, right and rear sides of the pufferfish breeding pond.

[0007] Furthermore, a drain pipe is connected to the side end of the water inlet, and a pumping pipe is connected to the side end of the water outlet. The pumping pipe is connected to the drain pipe through a pipe joint; and a water pump is installed on the surface of the drain pipe.

[0008] Furthermore, a motor is fixed on the left side of the connecting frame; and a threaded rod is connected to the right side shaft of the motor, with two sets of threaded rods symmetrically installed in the groove of the connecting frame.

[0009] Furthermore, a drive block is connected to the surface of the threaded rod, a connecting plate is welded to the side of the drive block, and a drive mesh plate is screwed to the lower end face of the connecting plate.

[0010] Furthermore, handles are welded to the left and right sides of the drive frame, an electric slide is embedded in the middle of the upper surface of the connecting frame, a waste collection frame is placed at the bottom of the pufferfish breeding pool, and a filter screen is provided on the upper surface of the waste collection frame.

[0011] Furthermore, the upper surface of the seed sieve plate is connected to the barrier plate via an electric push rod; and the holes on the surface of the barrier plate correspond to the screening holes of the seed sieve plate.

[0012] The beneficial effects of this utility model are as follows: the breeding pond for river grouper uses a sieving plate to divide the breeding pond into three breeding areas. A threaded rod rotates, driving a drive net plate on the side wall of the breeding pond to move towards the center. This drives river grouper fry from the two breeding areas towards the sieving plate, allowing smaller fry to pass through the mesh of the sieving plate and the barrier plate into the middle breeding area. This achieves an automatic fry sieving function, facilitating the timely sieving of river grouper fry with significant growth differences. This effectively reduces cannibalism among river grouper fry, saves on manual care, and increases the breeding rate of the river grouper breeding pond. The water in the pond flows towards the center through the inlet and outlet nets, guiding the river grouper fry's swimming direction and preventing fry in the middle breeding area from returning to the middle breeding area.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a breeding pond for culter grouper, including: a culter grouper breeding pond 1 and a drive frame 2, wherein the drive frame 2 is snapped and supported on the upper surface of the culter grouper breeding pond 1.

[0019] The inner wall of the rockfish breeding pond 1 is provided with a water inlet 13 and a water outlet 14. The drive frame 2 is welded with a connecting frame 22 on the front and rear sides. The connecting frame 22 is connected to a connecting plate 31 and a driving net plate 3 via a threaded rod 23. The driving net plate 3 is symmetrically attached to the inner wall of the left and right sides of the rockfish breeding pond 1. The upper end of the connecting frame 22 is connected to a seedling sieve plate 4 via an electric slide table 25. The seedling sieve plate 4 is inserted and distributed at the interval between the two sets of driving net plates 3. The surface of the seedling sieve plate 4 is provided with screening holes 41. The side of the seedling sieve plate 4 is attached with a barrier plate 43.

[0020] First, control the two sets of sieve plates 4 to move towards the center and fit together. Place the fry of the stream grouper on both sides of the sieve plates 4 in the stream grouper breeding pond 1 for breeding. After a period of breeding, the stream grouper fry grow rapidly. When differences appear, set a timer for sieve selection. When the set time is reached, the sieve plates 4 separate outwards. Control the screw rod 23 to rotate and drive the two sets of driving net plates 3 (the net surface of the driving net plates 3 is made of elastic band material) to move towards the center. At the same time, start the water pump to drain and pump water through the inlet 13 and the outlet 14. At this time, drive the stream grouper fry to move to the two sets of sieve plates 4. The smaller stream grouper fry pass through the screening hole 41 and enter between the two sets of sieve plates 4. The larger ones are left between the sieve plates 4 and the driving net plates 3. After the driving is completed, the barrier plate 43 moves down to prevent the stream grouper fry in the center from swimming out. Then, continue breeding for a period of time.

[0021] In this embodiment, a water-blocking plug 11 is installed on the right end face of the pufferfish breeding pond 1. The water inlet 13 and the water outlet 14 are respectively distributed on the left, right and rear sides of the pufferfish breeding pond 1. A drain pipe 12 is connected to the side end of the water inlet 13, and a water outlet 15 is connected to the side end of the water outlet 14. The water outlet 15 is connected to the drain pipe 12 through a pipe joint; and a water pump is installed on the surface of the drain pipe 12.

[0022] As a preferred implementation, the water pumping pipe 15 pumps water from the grouper breeding pond 1 through the water pumping net port 14 to the drain pipe 12, and discharges it from the water inlet net ports 13 on both sides through the drain pipe 12, so that the water in the pond flows from both sides to the middle, which facilitates the swimming direction of the grouper fry and at the same time prevents the fry in the middle breeding area from returning to the middle breeding area.

[0023] In this embodiment, a motor 21 is fixed to the left end of the connecting frame 22; and a threaded rod 23 is connected to the right shaft of the motor 21. Two sets of threaded rods 23 are symmetrically installed in the groove of the connecting frame 22. A drive block 24 is connected to the surface of the threaded rod 23, and a connecting plate 31 is welded to the side of the drive block 24. A driving net plate 3 is screwed to the lower end of the connecting plate 31. A contact sensor is provided on the side of the driving net plate 3. When the driving net plate 3 comes into contact with the seedling screening plate 4, the surface fish fry have been driven away, and the lower barrier plate 43 is moved down.

[0024] In a preferred embodiment, the two sets of threaded rods 23 rotate synchronously via motor 21, causing the drive block 24 to convert the rotational motion into linear motion, thereby driving the driving net plate 3 to move towards the center and driving the fish fry to the sieve plate 4.

[0025] In this embodiment, handles 26 are welded to the left and right sides of the drive frame 2, an electric slide 25 is embedded in the middle of the upper surface of the connecting frame 22, a waste collection frame 5 is placed at the bottom of the pufferfish breeding pool 1, and a filter screen 51 is provided on the upper surface of the waste collection frame 5.

[0026] In a preferred embodiment, the waste collection box 5 at the bottom can be removed for cleaning by moving the handle 26 out of the drive frame 2. The waste collection box 5 is used to collect waste produced by stream grouper fry.

[0027] In this embodiment, the upper end face of the seedling sieve plate 4 is connected to the barrier plate 43 via an electric push rod 42; and the holes on the surface of the barrier plate 43 correspond to the screening holes 41 of the seedling sieve plate 4.

[0028] As a preferred implementation, the electric push rod 42 pushes the barrier plate 43 to move up and down. When it moves up, the screening hole 41 of the sieve plate 4 is opened. When it moves down, it blocks the side stream grouper fry from passing through the screening hole 41, which helps to prevent the fry from flowing between the breeding areas on both sides.

[0029] This invention relates to a breeding pond for river grouper, which effectively solves the problem of cannibalism among river grouper fry due to large differences in individual growth and failure to separate them in time. It facilitates the timely screening of river grouper fry with large growth differences, effectively reduces cannibalism among river grouper fry, saves labor intensity in manual care, and improves the breeding rate of river grouper breeding ponds. It is suitable for river grouper breeding ponds.
