Industrialized circulation water tank and open-air pond combined shrimp farming method

Abstract

The invention discloses an industrialized circulation water tank and open-air pond combined shrimp farming method. Circulation water shrimp farming tanks and an open-air pond form one combination by the ratio of 1:50, the favorable condition that a circulation water aquaculture system is not affected by environmental climate is used, shrimp larvae are concentratedly thickened in advance, the shrimp larvae are cultivated for 30 days, and the large-size shrimp larvae with the average body length of 5-6 cm are transferred into the open-air pond after outdoor water temperature is suitable. The problems that shrimp farming in a traditional pond is greatly affected by environmental climate, conventional stocking time is delayed, traditional pond shrimp farming is long in farming cycle, the use ratio of land and water resources is low, the number of times of traditional pond shrimp farming is small, the output rate per unit water body is low, and the prices are similar as shrimps obtained through traditional pond farming come into the market in a concentrated mode can be solved.

Description

technical field [0001] The invention relates to a shrimp breeding technology, in particular to a shrimp breeding method in which an industrialized circulating pool and an open-air pond are combined. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei, is as famous as Chinese prawn and Penaeus monodon, and is one of the three high-yielding prawn species in the world; Successive breakthroughs have been made in disease breeding technology, and its breeding production has developed rapidly. By 2013, the total national breeding production had exceeded 1.3 million tons, accounting for about 50% of the world's total in that year. But at the same time, the traditional shrimp farming model is more and more dependent on the environment and pollutes the environment more and more seriously, which has led to many difficulties in shrimp farming production in recent years, and a serious decline in output and benefits. [0003] The prior art closest to the te...

Problems solved by technology

[0005] The application of this invention is restricted by climatic conditions, and it can only be cultured once a year, and the output per unit of water body is low; it is only suitable for raising shrimp in traditional ponds, and it is difficult to get rid of the influence of environmental climate on breeding production
