Crawfish culturing method

Abstract

The invention discloses a crawfish culturing method, which comprises steps of culturing pond building, pond cleaning, fertilization, waterseed planting, crayfish fry stocking, feedstuff feeding and crawfish disease prevention and control. Through accurate control over the technical steps of feedstuff managing, waterseed 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 and the quality of crawfish are effectively improved, and the commercial value of thecrawfish is further improved; through developing efficient pollution-free culturing for the crawfish, the surrounding crawfish culturing level can be improved, besides, the employment opportunities can be increased, the aquatic resources and the 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 crawfish is facilitated.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating crayfish. Background technique [0002] Crayfish are 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 to raise crayfish, and the enthusiasm for farming has been high. However, the current crayfish farming technology is not yet fully mature. The core technologies in key links such as management and shrimp disease prevention have not been fully popula...

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 to raise crayfish, and the enthusiasm for farming has been high. However, the current crayfish farming technology is not yet fully mature. The core technologies in key links such as management and shrimp disease prevention 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 commercial crayfish on the market are polluting Growing in a severe environment, there are serious quality problems, which threaten people's health and seriously affect the development of crayfish industrialization and large-scale farming
