Isolated breeding technique for cherax quadricarinatus eggs

Abstract

The invention discloses an isolated breeding technique for cherax quadricarinatus eggs. The breeding technique includes the steps: disinfecting ovigerous shrimps; separating the ovigerous shrimps; classifying the separated oval shrimps; implanting the oval shrimps; hatching the oval shrimps. The isolated breeding technique solves the problems of low survival rate and poor quality of artificial breeding, the hatching rate of the shrimp eggs can be increased by more than 70%-75%, the demand of the market for shrimp seed offspring can be effectively met, capital investment cost is reduced, and the isolated breeding technique is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of shrimp breeding and cultivation, in particular to a technology for in vitro cultivation of red-clawed crayfish eggs. Background technique [0002] Red claw crayfish (Cherax quadricarinatus), also known as "Australian freshwater lobster", originates in Australia and is also distributed in New Guinea. Guangdong and Hubei Trial breeding in two provinces was successful. Red claw crayfish is generally 50-100 grams in size, and the largest individual is 500-600 grams. It is a kind of freshwater shrimp with strong adaptability. It has a wide appetite, fast growth, tender meat, delicious taste and rich nutrition. , Japan, especially in the Chinese market by the majority of consumers. [0003] Although red claw crayfish can lay eggs many times a year, the survival rate of larvae in the wild natural environment is low and the quality varies greatly, which cannot meet the needs of the majority of farmers for lar...

Problems solved by technology

[0003] Although red claw crayfish can lay eggs many times a year, the survival rate of larvae in the wild natural environment is low and the quality varies greatly, which cannot meet the needs of the majority of farmers for larvae and larvae, and at the same time increases breeding The capital investment cost of the farmers, so the current manual treatment method is widely used to cultivate isolated shrimp eggs. Although some problems of low survival rate and poor quality have been solved under the current technical conditions, it still cannot meet the market demand for shrimp seedlings. Larvae Requirements
