Application of whiteleg shrimp culture feed

Abstract

The invention provides application of a whiteleg shrimp culture feed which is applicable to whiteleg shrimp at each stage. The application of the whiteleg shrimp culture feed is characterized in that the feed is mixed with water flea to feed young shrimps; the feed is mixed with water flea, alga and other live foods to feed the shrimps at the domestication stage; the whiteleg shrimp is completely fed with the feed after domestication. The whiteleg shrimp culture feed has the beneficial effects that the whiteleg shrimp culture feed is applicable to the culture of the whiteleg shrimp in each stage; the feed is prepared with the nutritional substances suitable for the growth of the whiteleg shrimp; the nutritional structure is reasonable; the growth promoting effect is obvious; the culture period is reduced; the immunity of the whiteleg shrimp can be improved; the prevalence rate can be reduced; moreover, the calcium can be absorbed well; the soft-shell shrimp is greatly reduced; the whiteleg shrimp at each stage is high in stability, high in utilization rate, and small in deposit at the bottom of a pool after being launched; the content of organic nitrogen and phosphorus in water can be effectively decreased, and the water purifying effect can be achieved, therefore, a good living environment is provided to the whiteleg shrimp.

Description

technical field [0001] The invention relates to the technical field of culture feed, in particular to the application of a culture feed for Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three shrimp species with the highest aquaculture output in the world today. Professor Zhang Weiquan of the Institute of Oceanology, Chinese Academy of Sciences was the first to introduce this shrimp from the United States, and broke through the breeding barrier in 1992, from the small test to the pilot test and then to the promotion of breeding all over the country. At present, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted breeding. The vannamei cultured in Yangjiabo Town, Hangu District, Tianjin is world-famous and has the reputation of "the hometown of fish and shrimp in China". Among them, the technology belonging to Penaeus vannamei is the most mature. The meat of Penaeus ...
