[0002] my country is a major aquaculture country in the world, with world-leading aquaculture technology and an annual aquaculture output of more than 50 million tons, ranking first in the world. my country has a wide variety of aquaculture species, providing delicious food and high-quality protein to meet people's growing demand for a better life. The great progress of aquaculture in my country is due to the development of the feed industry and the progress of the seed industry, especially in the breeding and cultivation of seedlings. Among them, seedling cultivation has greatly improved the efficiency and quality of aquaculture in my country. In terms of adult fish farming, seedlings with uniform specifications are stocked, and they eat evenly and grow fast, and the qualified rate of market specifications after being cultivated out of the pond can reach 100%. However, if the specifications of the stocked seedlings are uneven, due to the differences in individual growth rates, the sizes are uneven when they are out of the pond, and the qualified rate of market specifications is low. In addition to wasting manpower and material resources, it will also cause huge losses and aquaculture losses. On the other hand, especially some fish of the same species that cannibalize each other in the seedling stage, the large fish will eat the small fish if the specifications are slightly different. Therefore, a fry screening device for fishery farming is needed.
