Earthen pond breeding method of procambarus clarki

Abstract

The invention discloses an earthen pond breeding method of procambarus clarki. The method comprises the following technical steps: (1) pond reconstructing, cleaning and sterilizing; (2) preparing before parent shrimp breeding; (3) parent shrimp breeding; (4) fodder feeding; (5) daily management; (6) wintering management; (7) seedling cultivation; and (8) seedling catching. After the testing of themethod, a large number of seedlings are produced in a base of about 5,000 mu (1 mu is about 666.7 square meters), more than 50,000 shrimps can be bred per mu, and specifications are 140 to 160 high-quality shrimp seedlings per kilogram, thus offering safeguard for the breeding of grown shrimp. Though the breeding amount of lobster individuals is small, survival rate is relatively high. A large amount of parent shrimps ensures the amount of seedlings. The breeding of procambarus clarki is not synchronous and seedling specifications in a pond are inconsistent, but seedlings required by production can be bred and demand for future breeding can be fulfilled. With batches of seedlings, future production and development can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to an earthen pond breeding method for Procambarus clarkii. Background technique [0002] Procambarus clarkii (Procambarus clarkii), English name Red swampcrayfish, commonly known as lobster, crayfish, etc., is a freshwater economical shrimp, which is widely welcomed by people because of its delicious meat. The market price keeps rising, especially in the past two years, the highest wholesale price has reached 30 yuan per kilogram, and the supply is still in short supply. Moreover, there is an obvious off-season problem in the market (supply from April to October). In the past, this kind of shrimp was considered to be a foreign organism, and it did not attract the attention of domestic research institutions and promotion agencies. Therefore, few people specialized in the whole process from the beginning of biology to breeding and breeding of this shrimp. Withou...

Problems solved by technology

Moreover, there is an obvious off-season problem in the market (supply from April to October)

In the past, this kind of shrimp was considered to be a foreign organism, and it did not attract the attention of domestic research institutions and promotion agencies. Therefore, few people specialized in the whole process from the beginning of biology to breeding and breeding of this shrimp. There is no formal development, and the output mainly depends on wild capture. After the price rises, the amount of natural resources will become less and less. In the future, the supply of the market must be solved by breeding
