Technical Field
The invention relates to an aquaculture technology, in particular to a large-size fry double-layer shed cultivation method and system for red crayfish, and relates to a red crayfish fry cultivation technology.
Background
The red crayfish is also called Australia freshwater lobster, four-ridge bare-shell crayfish, red crayfish, academic name four-ridge bare-shell procambarus clarkia: (Cheraxquadricarinatus) Belonging to the genera of arthropoda, Crustacea, decapod, quasi-crayfish and light shell shrimp, the lobster meat has larger individuals and the appearance is close to that of the lobsters in the sea, but belongs to the shrimp species living and breeding in fresh water, the meat quality is compact, smooth and crisp, the taste is delicious and delicious, and the lobster species has higher economic value in the world.
The original producing area of the red chelonian is northern Australia, China is introduced into the red chelonian by the aquatic product research institute in Hubei in 1992, the suitable temperature range is wide and is 5-35 ℃, under the conditions of suitable water temperature and feeding environment, the red chelonian can mature sexually in the same year, the red chelonian can mate and lay eggs for many times in one year, and the laying period is in late spring and early summer under natural conditions. The original latitude of the red chelonian is greatly different from the internal latitude of Jiangsu, so that the red chelonian cannot be bred in the Jiangsu through winter naturally, the fries can be bred only when the temperature of the pond water is over 20 ℃, the mutual killing rate is high when the high-density large-size fries are bred in an indoor greenhouse, and the breeding survival rate is low.
