According to the device, cherax quadricarinatus seeds with different specifications are captivated, and the survival rate of the cherax quadricarinatus seeds can be greatly increased.

Description

Technical field [0001] The invention belongs to the technical field of industrialized cultivation of crayfish, and specifically relates to a set of red crayfish juvenile sieving device and a use method thereof. Background technique [0002] Red crayfish is currently one of the best freshwater prawns in the world. It has the characteristics of large size, fast growth, and high meat content (the abdomen accounts for 42% to 47% of the total weight). Studies have shown that the intraspecific struggle of red crayfish is one of the main factors that plague the promotion of industrial farming. In particular, red crayfish of different specifications often struggle with each other or eat and cause a serious decrease in survival rate. Therefore, how to reduce red crayfish The intraspecific struggle of crayfish is a key technical issue in the large-scale cultivation of red crayfish. At present, there have been many domestic and foreign researches on reducing intraspecific struggles, which ...
