Crayfish larva breeding method for rice field culture

Abstract

The invention discloses a crayfish larva breeding method for rice field culture, and relates to the technical field of crayfish breeding. The method comprises the steps of breeding pool building, crayfish larva selection, seed crayfish feeding, crayfish larva incubation, crayfish larva feeding, applicability feeding and crayfish larva choosing. In the process of artificial crayfish larva breeding, directional manual intervention is applied, so that bred crayfish can better adapt to rice field growing environment, the bred crayfish can be matched with the rice field to obtain aquaculture income, and the income of farmers is increased; according to crayfish growing in the rice field, on one hand, predation locust insects and aquatic pest can be increased; on the other hand, rice ear fallen flowers can be adopted as crayfish food intake.

Description

technical field [0001] The invention relates to the technical field of crayfish breeding, in particular to a method for breeding crayfish seedlings used for paddy field cultivation. Background technique [0002] Crayfish, belonging to the phylum Arthropoda, was introduced to my country from Japan in the late 1930s. Crayfish have the living habit of burrowing, destroying dams, threatening the survival of fry, and causing certain damage to agricultural production and fishery production. Therefore, early people have always eliminated them as harmful organisms. In recent years, crayfish has been sought after because of its delicious meat, and the market prospect is good. However, due to the lack of artificial breeding of crayfish, people catch a large number of wild crayfish, making their natural population less and less. The market is in short supply and the price has risen sharply. In recent years, more and more crayfish have been cultured artificially, and most of them are b...

Problems solved by technology

In recent years, crayfish has been sought after because of its delicious meat, and the market prospect is good. However, due to the lack of artificial breeding of crayfish, people catch a large number of wild crayfish, making the natural population less and less. The market is in short supply and the price has risen sharply

In recent years, more and more crayfish have been cultured artificially, and most of them are built in special breeding ponds for breeding. In rural areas, large areas of paddy field water have not been effectively used, which seems wasteful.
