[0033] Example 1

[0034] Please refer to Figure 1, a fry sorting device for Decapterus maruadsi, comprising a fish-catching support body 1, a fish-sorting pipe 2, and a counter 3 arranged in sequence along the swimming direction of the fry; further comprising an underwater LED spotlight 4 arranged in front of the fish-catching support body 1; the number of the underwater LED spotlights 4 is 2. The underwater LED spotlight 4 emits white light in a directional manner, and the flashing frequency of the lamp is 0.5HZ. The underwater LED spotlight 4 comprises a body and a holding rod connected to the body.

[0035] The fish-catching support body 1 comprises a fish-sorting net 11 arranged in a conical shape. A circular fish-sorting net mouth support frame 12 is arranged at the large-mouth end of the fish-sorting net 11. The small-mouth end of the fish-sorting net 11 is communicated with the fish-sorting pipe 2. The fish-sorting net mouth support frame 12 is a ring formed by connecting the steel ring pipes end to end. The diameter of the fish-sorting net mouth support frame 12 is 50 - 60 cm. The fish-sorting pipe 2 is a plastic transparent pipe. The diameter of the fish-sorting pipe 2 is 50 - 75 mm.

[0036] The fish-catching support body 1 is arranged in a fish-raising pond 5. One end of the fish-sorting pipe 2 far away from the fish-raising pond 5 is arranged in a fish-sorting pond 6. The fish-sorting pipe 2 drains the water in the fish-raising pond 5 into the fish-sorting pond 6 by means of siphonage.

[0037] The counter 3 comprises a light beam emitter and a light beam receiver. The light beam emitter is installed at the upper end of the pipeline of the fish-sorting pipe 2, and the light beam receiver is installed at the lower end of the pipeline of the fish-sorting pipe 2, corresponding to the position of the light beam emitter.

[0038] The principle of the above fry sorting device for Decapterus maruadsi:

[0039] A handheld underwater LED spotlight is arranged in front of the fish-sorting net. The spotlight can emit white light in a directional manner, and the flashing frequency of the lamp is 0.5HZ. The spotlight points to the fish-sorting net mouth support frame of the fish-sorting net. By using the characteristic that Decapterus maruadsi is sensitive to light, the fish in the fish-raising pond can be driven into the fish-sorting net without damage and enter the fish-sorting pond through the fish-sorting net. A counter is arranged at the end of the fish-sorting pipe to automatically calculate the number of Decapterus maruadsi entering the fish-sorting pond. When the number of sorted fish reaches the requirement, the fish sorting stops.

[0040] The aperture of the fish-sorting net of the fry sorting device for Decapterus maruadsi is 50 - 60 cm, which can avoid too many fish swimming into the fish-sorting pipe together. The bottom of the fish-catching net is connected to the fish-sorting pipe. The fish-sorting net mouth support frame is a steel ring pipe with a diameter of 50 - 75 mm (depending on the size of the fish to be sorted). When sorting fish, make the fish-sorting pipe form a siphon effect between the fish-raising pond and the empty pond, and fill the fish-sorting pipe with water. Then drive the Decapterus maruadsi in the fish-raising pond towards the fish-sorting net. The Decapterus maruadsi entering the fish-sorting net will instinctively drill towards the bottom of the net, enter the fish-sorting pipe, and then swim into the empty pond for fish sorting. Using this method to sort fish causes much less fright and surface damage to the fish than directly fishing with a net, and significantly improves the survival rate of Decapterus maruadsi.

[0041] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in related technical fields, shall be similarly included in the patent protection scope of the present utility model.
