Procambarus clarki ovum in-vitro breeding technique

Abstract

The invention put forwards an excised cultivation technology of procambarus clakii eggs according to developmental biology principle. The key points of the technology are the separation between parent prawns and eggs of berried prawns, the classification of the eggs, and respectively artificial hatching of the eggs. The steps of the invention are as follows: firstly, the berried prawns are sterilized; secondly, the parent prawns and the eggs are separated; thirdly, the eggs in different development stages are classified; fourthly, nidation of the eggs; fifthly, the hatching of the eggs. The invention has a high egg hatching rate, uniform sized young hatching prawns and a high commodity value. The cultivation technology can effectively prevent the young prawns from eating each other; therefore the survival rate of the young prawns is improved. Because the berried prawns do not need to be reared, cultivation cost is reduced and the transportation of prawn eggs is more convenient.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to the in vitro cultivation technology of Procambarus clarkii eggs. Background technique [0002] Procambarus clarkii (the scientific name is also called "crawfish clarkii", commonly known as "lobster", "crayfish", hereinafter referred to as "lobster".) Lobster, since it was cooked and made into delicious food, the market demand has become more and more Big. Especially in recent years, wild lobsters have become an important factor restricting the development of the lobster industry due to a large number of catches and the gradual depletion of resources. In order to solve the above problems, aquatic science and technology personnel have conducted research on the artificial propagation technology of lobster, which includes the cultivation of shrimp seedlings, the survival and growth of shrimp larvae, and the reproduction of adult shrimp, etc. At present, the breeding method of shrimp seedli...
