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

Embodiment Construction

[0046] The implementation of the present invention will be described in further detail below. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0047] A method for off-season industrial culture of Penaeus vannamei, the method comprising steps as follows:

[0048] (1) Selection of farm site, design of breeding workshop and shrimp pond,

[0049](1) Conditions for farm site selection: the farm is located in a quiet environment, and the background noise of the environment is less than 45db, because it is obtained through comparative experiments that when the background noise of the environment is greater than 45db, it will have a significant impact on the growth of prawns. The relationship between the increase of noise and the linear decrease, the location with sufficient water source and underground hot water;

[0050] (2) Breeding workshop: The breeding workshop is designed for thermal insulation, and...

Abstract

The invention relates to a method for off-season industrial culture of Penaeus vannamei, which comprises the following steps: (1) site selection of the farm, design of the culture workshop and shrimp pond, (2) preparation before releasing seedlings, (3) temporary cultivation of seedlings , (4) management during the cultivation period and (5) harvest. The method of the present invention can carry out off-season cultivation of Penaeus vannamei in northern regions, and is not limited by seasons and temperatures compared with traditional cultivation, and can control environmental conditions such as temperature, light, and dissolved oxygen in the optimum growth environment of Penaeus vannamei, It can prevent the cross-infection of pathogenic microorganisms, reduce the occurrence of diseases, high-density intensive cultivation, and the yield is obviously improved, avoiding the period when the prawns are concentrated on the market, adjusting the market supply, and helping to increase farmers' income. At the same time, the method of the invention effectively utilizes the idle time in winter Breeding has greatly improved the utilization rate of land resources.

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...
