Fresh water farming method of penaeus vannamei boone

Abstract

The invention provides a farming method of penaeus vannamei boone, The method can increase the yield and quality of the penaeus vannamei boone. The method includes the steps that a pool is prepared, seedling is bred and fodder is prepared, exuviation and synchronous growth are promoted, and catching is processed. The invention has the advantages that feeding density is reduced and survival rate of shrimps is high. The problem of the survival rate of shrimps influenced by fry degradation because of high-density feeding module is solved. The water quality can be controlled during feeding. The left fodder, excreta of penaeus vannamei boone, dead algae and the like can be collected to the central area of the pool by air circulation in the process of oxygenation, a relative large clean water area is formed at the surroundings of the pool, and a clean survive room for shrimps is provided. The daily management to shrimps and pool is processed during feeding, shrimp diseases are reduced. The promoted exuviation and synchronous growth enable the shrimps to be average in size and stable in quality. When the shrimps grows to 8 to 10 centimeters, the shrimps can be caught in time, the load to the pool is relieved, the diseases are controlled, good water environment of the pool is ensured, and the yield of shrimps is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating Penaeus vannamei. Background technique [0002] Penaeus vannamei, also known as white-legged shrimp, white-legged shrimp, and white-legged shrimp, is native to the Pacific coast of South America, and is mainly distributed in the northern part of Peru to the coast of the Gulf of Mexico, with the most concentrated distribution in the coastal waters of Ecuador. It is one of the three excellent shrimp species (Penaeus vannamei, Penaeus monodon, Penaeus sinensis) with the highest breeding output in the world. It has the advantages of strong vitality, wide adaptability to salinity and temperature, strong disease resistance, high survival rate, rapid growth, high meat yield, long survival time out of water, suitable for high-density breeding, etc. It is an intensive high-yielding Excellent cultivars. [0003] Penaeus vannamei belongs to Arthropoda, Crustac...

AI Technical Summary

Problems solved by technology

[0021] 4. The bait coefficient is generally low;

[0029] 6. Shrimp farming in greenhouses: adopting greenhouses against the season or prolonging the breeding time requires a large investment;

[0030] 7. Industrial shrimp farming: one-sided pursuit of high yield, many farming techniques have not been refined, the breeding effect is not ideal, and the penetration rate is not high
