Rice field ecological crawfish culture method

Abstract

The invention discloses a rice field ecological crawfish culture method, and relates to the crawfish culture technical field; the culture method comprises the following steps: rice field altering; rice field disinfection and fertilization; bait mixotrophic culture; shrimp seed inputting and feeding; field management; adult shrimp catching. In rice field altering, ridges are heightened, and smooth stop plates are arranged, thus preventing crawfish from escaping; a space is reserved in the rice field so as to grow crawfish favorable waterweeds; in addition, crawfish favorable fries and loach seeds are polycultured in the field. The method culture the crawfish in the rice field so as to simultaneously obtain aquatic product culture incomes, thus increasing farmer incomes; the crawfish in the rice field can capture grasshopper insects and aquatic biology; the rice spikes can serve as crawfish foods, thus improving crawfish mouthfeel.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a method for cultivating ecological crayfish in paddy fields. 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 built in sp...

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.
