Problems solved by technology

[0003] However, when the shrimp seedlings are moved from the indoor seedling ponds to the growing ponds, the stress death caused by environmental changes or the inadaptability of the shrimp seedlings has caused huge economic losses to the majority of farmers. The feed eaten by Penaeus vannamei and the excrement of Penaeus vannamei will be deposited on the bottom of the pond. If it cannot be effectively recycled for a long time, it will lead to the deterioration of the bottom environment of the culture pond, which is an important factor that causes the occurrence of diseases of Penaeus vannamei. Source, research and development of a circulation culture method of Penaeus vannamei, thereby reducing the stress death of Penaeus vannamei, and the impact of sludge sedimentation on the bottom of the pond on Penaeus vannamei is an urgent problem to be solved

Abstract

The invention discloses a circulation breeding method of whiteleg shrimps. The circulation breeding method of whiteleg shrimps comprises the following steps: step one, building up a circulation breeding system comprising a breeding tank, a primary sedimentation tank, a secondary sedimentation tank and a buffering tank; step two, pumping water in the breeding tank into the buffering tank, and adding chlorine dioxide to obtain sterilizing water; removing sludge at the bottom of the breeding tank, adjusting the included angle between the bottom surface of the breeding tank and the horizontal plane to be 15-20 degrees, spreading a mixture of quick lime and plant ash until the mixture is dry and cracks, mounting a plurality of first inclined plates, a plurality of second inclined plates and a filter screen, and injecting the sterilizing water; step three, arranging an aerator; and step four, before breeding the whiteleg shrimps out of cages, carrying out fertilizer and water treatment to obtain breeding water, and feeding young shrimps, wherein the feeding density of the young shrimps is 60,000-80,000 young shrimps in every mu. The circulation breeding method of the whiteleg shrimps has the beneficial effects that physical removal and chemical elimination are combined effectively, the sterilizing effect is improved, the sludge at the bottom of the tanks are removed by circulation of the primary sedimentation tank and the secondary sedimentation tank, meanwhile, noise pollution of the bottoms of the tanks is reduced, and muddy pollution of the bottom sludge is reduced.

Description

technical field [0001] The invention relates to the field of culture of Penaeus vannamei. More specifically, the present invention relates to a method for circulating culture 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. [0003] However, when the...
