Abstract

The invention discloses a young cherax quadricarinatus screening device and a use method, and belongs to the technical field of cherax quadricarinatus industrial aquaculture. The device comprises a screening device body, a water flow control device and an inducing device, the screening device body comprises a temporary aquaculture tank, a primary screening tank, a secondary screening tank, a primary screening plate, a secondary screening plate, a first escape-proof plate and a second escape-proof plate, the temporary aquaculture tank and a water drainage tank is separated through the first escape-proof plate, the temporary aquaculture tank and the primary screening tank is separated through the primary screening plate, the primary screening tank and the secondary screening tank is separated through the secondary screening plate, the secondary screening tank and a water inlet tank is separated through the second escape-proof plate, the inducing device comprises a light source and a bait, and the water flow control device controls water to flow into the temporary aquaculture tank from the secondary screening tank. 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 ...
