Breeding method to improve anti-stress ability of Penaeus vannamei

Abstract

The invention discloses an aquaculture method for improving anti-stress capability of penaeus vanmamei. The method includes: step one, establishing an aquaculture system which comprises an aquaculture pond, an exchange pond, a precipitation pond and a buffer pond; step two, pumping water from the aquaculture pond to the exchange pond, adding chlorine dioxide and bleaching powder into the exchange pond to obtain sterilization water, laying quick lime at the bottom of the aquaculture pond until the bottom of the pond cracks, sweeping the quick lime to cracks, spraying a microbial regulating agent, and mounting a plurality of first oblique plates and a plurality of second oblique plates in the aquaculture pond; step three, arranging an aerator in per mu of the aquaculture pond; step four, performing fertilizer and water treatment. By effective combination of physical removal and chemical elimination, water and sludge are treated respectively, sterilization effects are improved so as to alleviate stress reaction of penaeus vanmamei radically, and precipitate treatment and water source exchange do not cause strong flow fluctuation or noise, so that stress reaction of penaeus vanmamei is further avoided and alleviated while a living environment of penaeus vanmamei is guaranteed.

Description

technical field [0001] The invention relates to the field of culture of Penaeus vannamei. More specifically, the invention relates to a culture method for improving the anti-stress ability of Penaeus vannamei. Background technique [0002] Penaeus vannamei, whose scientific name is Penaeus vannamei, belongs to the phylum Arthropoda, with an average lifespan of at least 32 months, and an adult body up to 24cm long. The legs are often chalky, and the meat is delicious, with high economic value. The processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32°C. It also has a wide salt range and can grow at a salinity of 1-40‰. It is an excellent desalinated breeding variety. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country. Shrimp fry, shrimp nauplii or broodstock are available in Xiamen, Beihai, Nanning and Guangzhou in my country.

Problems solved by technology

[0003] However, when the shrimp seedlings are moved from the indoor nursery pond to the grow-out pond, due to the change of bait and environment, the shrimp seedlings will not adapt and cause stress death, which has caused huge economic losses to the majority of farmers. It is an urgent problem to be solved at present to develop a scientific and reasonable breeding method that can improve the anti-stress ability of Penaeus vannamei and reduce the early loss of shrimp fry.
