Method suitable for industrial aquaculture of prawns in south

Abstract

The invention provides a method suitable for industrial aquaculture of prawns in south, relates to the technical field of aquaculture of litopenaeus vannamei, and solves the technical problems that the survival rate of the prawns is lower and the production benefits are not ideal through open-air industrial aquaculture in the south. The method comprises steps as follows: a filtering pond, an aquaculture pond and an overwintering greenhouse are set up, seawater flows to the aquaculture pond after passing by the filtering pond and the filtered seawater is subjected to secondary disinfection anddetoxification in the aquaculture pond; the ventilation condition of the overwintering greenhouse is changed, so that the temperature and the atmospheric pressure in the overwintering greenhouse meetthe proper aquaculture standard; bacterium and virus carrying detection is performed on young prawns, and qualified young prawns are added to the aquaculture pond. The method is used for realizing aquaculture of prawns in the south all the year round.

Description

technical field [0001] The invention relates to the technical field of Penaeus vannamei culture, in particular to a method suitable for industrial culture of Penaeus vannamei. Background technique [0002] At present, the open-air factory farming in the south increases the light intensity of the cultured water body due to the open-air farming method, and the photosynthesis of the algae in the water body becomes stronger, which makes it easier for the shrimp to produce astaxanthin. The body color of the shrimp rich in astaxanthin is better than that of the indoor cultured shrimp. However, the open-air culture method also has its limiting factors. When the climate changes greatly, the water quality will fluctuate rapidly in the open-air culture, which will cause the prawns to be easily stressed and cause the incidence of prawns to increase. , the pathogen is easy to spread, causing a large number of prawns to die, resulting in a low breeding success rate; building a greenhouse...
