Problems solved by technology

With the rapid development of crayfish paddy farming, seedlings have become the bottleneck of the crayfish farming industry. Due to the biological characteristics of crayfish reproduction, the amount of broodstock and seedlings in each group is limited, generally between 100 and 300, although it has been reported that The factory breeding of crayfish has been successful, but it is far from meeting the needs of production

Abstract

The invention discloses a method for breeding seedlings of crayfish in paddy field in early autumn. The rice field structure is transformed, rice stubble is used for crayfish to build mating and spawning places, water level control is used to induce mating and spawning of crayfish, and barriers are set in the feeding area to optimize parent shrimps. , parent shrimp feed feeding, seed feeding, seed fishing and production steps to enhance crayfish physique, improve the survival rate of crayfish overwintering, reduce the chance of cannibalism of shrimp seedlings, improve the size of shrimp seedlings, and obtain crayfish The success of ecological breeding in early autumn breeding in rice fields has realized the large-scale and mass production of early autumn breeding seedlings of crayfish.

Description

technical field [0001] The invention relates to the technical field of crayfish breeding seedlings, in particular to a method for early autumn breeding of crayfish seedlings in rice fields. Background technique [0002] Procambarus clarkii belongs to Arthrophyta, Crustacea, Crawfishidae, Procambarus genus, also known as crayfish, scientific name Procambarus clarkii (hereinafter collectively referred to as crayfish), its delicious meat, rich nutrition, popular among people Love is the main species of shrimp farming at present. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, artificial scientific breeding is used to meet market demand. With the rapid development of crayfish paddy farming, seedlings have become the bottleneck of the crayfish farming industry. Due to the biological characteristics of crayfish reproduction, the amount of broodstock and seedlin...
