A kind of pollution-free and high-efficiency breeding method of crayfish

Abstract

The invention discloses an efficient pollution-free culturing method for red swamp crayfishes. The method includes the steps of pond selection, pre-stocking preparation, crayfish fry stocking, daily managing, catching and others. Through accurate control over the technical steps of feedstuff managing, aquatic plant cultivating, stocking density, water quality regulating and controlling, disease control and others, efficient and pollution-free effects in the whole culturing process are achieved, the yield of the red swamp crayfishes is effectively increased, the quality of the red swamp crayfishes is effectively improved, and the commercial value of the red swamp crayfishes is improved; through developing efficient pollution-free culturing for the red swamp crayfishes, the culturing level of peripheral red swamp crayfishes can be improved, besides, the employment opportunities can be increased, the aquatic resources and environment are protected, optimization of the rural industrial structure is accelerated, rural incomes are increased, and acceleration of local industrialized and large-scale culturing for the red swamp crayfishes is facilitated.

Description

technical field [0001] The invention relates to a pollution-free and high-efficiency breeding method for crawfish, which belongs to the technical field of aquaculture. Background technique [0002] Crayfish, also known as crayfish, is the most widely distributed and most commonly farmed freshwater crayfish in the world. The shrimp meat is delicious, unique in flavor, rich in nutrition, high in protein, low in fat, rich in calcium, phosphorus, iron, etc. It has become a delicious food on the table of urban and rural residents, and is increasingly favored by domestic and foreign markets. One of the main aquatic products that earn foreign exchange. In recent years, with the sharp increase in market demand, the market price has risen year by year, which has stimulated the enthusiasm of the masses for farming crayfish, and the enthusiasm for farming has been high. However, the current farming technology for crayfish is not yet fully mature. The core technologies of key links su...

Problems solved by technology

In recent years, with the sharp increase in market demand, the market price has risen year by year, which has stimulated the enthusiasm of the masses for farming crayfish, and the enthusiasm for farming has been high. However, the current farming technology for crayfish is not yet fully mature. The core technologies of key links such as preparation, daily management and shrimp disease prevention and control have not been fully popularized, and extensive and empirical farming is still the mainstay, and production is extremely unstable. At the same time, due to the strong environmental adaptability of crayfish, many commodities on the market Crawfish grows in a heavily polluted environment, and there are serious quality problems that threaten people's health and seriously affect the development of industrialization and large-scale farming of crayfish
