Anti-season penaeus vanmamei factory culture method

Abstract

The invention relates to an anti-season penaeus vanmamei factory culture method. The anti-season penaeus vanmamei factory culture method comprises the following steps: (1) selecting the site of a culture field, and designing a culture workshop and a penaeus vanmamei pond; (2) preparing before releasing young penaeus vanmamei; (3) temporarily culturing by putting the young penaeus vanmamei into the penaeus vanmamei pond; (4) managing in a growing period; and (5) harvesting. Anti-season penaeus vanmamei culture can be carried out in a northern area through the anti-season penaeus vanmamei factory culture method disclosed by the invention; compared with traditional culture, the anti-season penaeus vanmamei factory culture method is not limited by seasons and temperature and is capable of controlling the environmental conditions, such as temperature, illumination and dissolved oxygen, in a most proper penaeus vanmamei growing environment, preventing cross infection of pathogenic microorganisms and reducing disease occurrence; by means of high-density intensive culture, the yield is obviously increased; concentrated appearance of penaeus vanmamei on the market is avoided; the market supply is adjusted; the rural income is increased easily; simultaneously, culture is carried out by effectively utilizing the idle time in winter; and therefore, the utilization rate of land resources is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for off-season industrial culture of Penaeus vannamei. Background technique [0002] Penaeus vannamei, scientific name Litopenaeus vannamei, is a wide-temperature and wide-halt tropical shrimp. Penaeus vannamei has thin shell and fat body, delicious meat, high meat content, rich nutrition, fast growth, strong disease resistance, strong adaptability to changes in water environment factors, etc. The optimum growth water temperature is 22-35°C. When the water temperature is lower than 18°C, the food intake is reduced and the growth is slow, and when the water temperature is lower than 15°C, the feeding is stopped. At present, pond farming is the main method, and the breeding cycle is about 90 days, and the price is low in the centralized market. Due to the low temperature in the northern region, the suitable culture period for Penaeus vannamei is relativel...

Problems solved by technology

[0004] At present, the main species of industrial farming is seawater fish, which has high economic value, few breeding diseases, and mature farming technology. The sharp drop requires active adjustment of cultured varieties. Industrialized culture of Penaeus vannamei has a short cycle, low breeding cost, and water saving. With the shortage of land resources, the production of Penaeus vannamei cultured in ponds has dropped sharply, and the price of Penaeus vannamei has dropped sharply. vannamei industrial farming is replacing seawater fish industrial farming has become a trend, so it is very necessary to implement off-season industrial farming of vannamei effectively as soon as possible
