Problems solved by technology

[0005] However, at present, the culture cycle of Penaeus vannamei is generally long, and the vannamei must reach the market size of prawns before they can be sold at a good price, and to meet the weight requirements of this size, the culture time must be at least 90 days, which is too long The breeding cycle also means to bear greater breeding risks, so it is urgent to develop a culture method of Penaeus vannamei that can reach the market size of prawns and shorten the breeding cycle

Abstract

The invention discloses a culture method of Penaeus vannamei for shortening culture period. The culture method comprises the steps that step 1, pH value and transparency of the breeding pond water are controlled, and the inner portion of the breeding pond is provided with a pollutant discharge mechanism and a water circulation mechanism; step2, shrimp seeds are put in from a shallow water area; step 3, 1-5 days after the shrimp seeds are put in, nutrient compound is feed according to a first feeding method; step 4, nutrient compound feeding is stopped at the 6th day after the shrimp seeds are put in, the nutrient compound is replaced by fitness feed, the fitness feed is used for feeding the shrimps for 20-35 days according to a second feeding method; step 5, the fitness feed is replaced by meat adding feed, and the shrimps are fed by the meat adding feed according to a third feeding method. The culture method has the advantages of shortening the culture period, increasing the survival rate and yield per mu of Penaeus vannamei, and reducing the feed coefficient.

Description

technical field [0001] The invention relates to the field of culture of Penaeus vannamei. More specifically, the present invention relates to a culture method of Penaeus vannamei that shortens the culture cycle. Background technique [0002] Penaeus vannamei, whose scientific name is Penaeus vannamei, belongs to the phylum Arthropoda. It is a wide-temperature and wide-halt tropical shrimp. It looks exactly like Penaeus sinensis and Penaeus megi. Its average life span can exceed 32 months. Thin, the normal body color is light blue-gray, the whole body has no markings, and the legs are often chalky, so it is called white-limbed shrimp. The meat is delicious and has high economic value. [0003] At present, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted farming. The vannamei cultured in Yangjiabo Town, Hangu District, Tianjin is world-famous and has the reputation of "the hometown of fish and shri...
