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 crayfishes in early autumn in a rice field. Through rice field structure transformation, rice stubbles are reserved to create a mating spawning site for the crayfish, crayfish mating and spawning are induced through water level control, obstacles are arranged in a throwing area, parent crayfishes are preferably selected, parent crayfish are fed with afeed, fries are fed with the feed, fry fishing and yield are increased, the crayfish overwintering survival rate is increased, the crayfish fry self-killing probability is reduced, the crayfish fry specification is increased, and the crayfish yield is increased. The success of ecological breeding of early autumn breeding of the crayfish in the rice field is achieved, and large-scale and batch production of early autumn breeding seedlings of the crayfish is achieved.

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...
