[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-3 and Figure 5 Existing black pike fry breeding devices result in individual differences in black pike fry during breeding, making it inconvenient to isolate black pike fry of different sizes. In order to solve this technical problem, this embodiment discloses the following technical content.

[0027] A black-spotted pike fry breeding device includes a breeding tank 1 with several first placement holes 2 evenly spaced on the front and back sides, and a second placement hole 3 on the left side of the first placement hole 2. A first connecting rod 5, which is fixedly connected to the front and back sides of a first isolation net 4, is slidably connected to the first placement hole 2. A second connecting rod 7, which is fixedly connected to the front and back sides of an isolation plate 6, is slidably connected to the second placement hole 3. A second isolation net 8 is provided on one side of the first isolation net 4, and a first connecting rod 5 is fixedly connected to both the front and back sides of the second isolation net 8. The first connecting rod 5 on the second isolation net 8 is slidably connected to the first placement hole 2.

[0028] Black-spotted pike fry are released into rearing pond 1 for culture. During the rearing process, individual differences will occur among the fry; some will grow larger than others. Since black-spotted pike are ferocious carnivorous fish, they may exhibit severe cannibalism. Therefore, it is necessary to separate fry of different sizes for rearing. This is achieved using a first isolation net 4 and a second isolation net 8. The mesh density and size of the first isolation net 4 and the second isolation net 8 are different, which can separate fry of different sizes and prevent cannibalism caused by mixing different fry. The first connecting rods 5 at the front and rear ends of the first isolation net 4 and the second isolation net 8 are connected as needed. To determine the desired size of the breeding area, insert the first connecting rod 5 into the corresponding first placement hole 2. Then, the black-spotted pike fry can be separated according to their different sizes. After separating the black-spotted pike fry, to prevent the smaller ones from swimming to the adjacent breeding area through the holes on the first isolation net 4 and the second isolation net 8, insert the second connecting rod 7 at the front and rear ends of the isolation plate 6 into the second placement hole 3 on the left side of the first isolation net 4 or the second isolation net 8 to prevent the black-spotted pike fry from swimming around. The lower surface and front and rear sides of the first isolation net 4, the isolation plate 6, and the second isolation net 8 are attached to the inner side of the breeding pond 1. The breeding pond 1 can be divided into different breeding areas according to the needs.

[0029] Example 2: Existing black-spotted pike fry rearing devices have specific requirements for feed, making it inconvenient to provide live feed. Therefore, this example uses the following technical solution, such as... Figures 1-4 As shown;

[0030] Square through holes 9 are provided at the upper middle of both sides of the cultivation pool 1, and an arc-shaped corner 10 is fixedly connected to the middle of the square through hole 9. The bottom of the inner side of the square through hole 9 is set as a grid plate 11.

[0031] Feeding mechanisms are fixedly connected to the upper middle of both sides of the rearing pool 1. The feeding mechanism is composed of a live feed box 12, an inclined bottom plate 13, a discharge port 14, a storage trough 15, an automatic telescopic rod 16, a baffle 17, and a slot 18. A support plate is fixedly connected to the outer bottom surface of the live feed box 12, and an inclined bottom plate 13 is fixedly connected to the inner bottom surface of the live feed box 12. A discharge port 14 is opened at the inner bottom of the live feed box 12. The discharge port 14 is connected to the square through hole 9 on the rearing pool 1. A storage trough 15 is opened inside the inner end of the live feed box 12. An automatic telescopic rod 16 is fixedly connected to the front, middle, and rear sides of the upper inner end of the storage trough 15. The output end of the automatic telescopic rod 16 is fixedly connected to the baffle 17. The baffle 17 is slidably connected in the storage trough 15. A slot 18 is opened in the middle of the discharge port 14. The bottom end of the baffle 17 is engaged with the slot 18.

[0032] Live food for feeding black-spotted pike fry is introduced through the square through-hole 9. The inner side of the square through-hole 9 is provided with an arc-shaped corner 10 to prevent black-spotted pike from swimming to the connection between the live food box 12 and the bottom of the rearing pond 1 through the square through-hole 9. The bottom of the inner side of the square through-hole 9 is provided with a mesh plate 11 to prevent damage to the live food during feeding. When the black-spotted pike fry need to be fed, the food is put into the live food box 12. Then, the automatic telescopic rod 16 is activated. The output end of the automatic telescopic rod 16 moves upward with the baffle 17, and the live food will be put into the rearing pond 1 through the outlet 14 and the square through-hole 9. The bottom of the live food box 12 is a sloping bottom plate 13 to prevent live food from being left in the live food box 12, so that the live food can be completely put in.
