Low fish powder feed for litopenaeus vannamei

Abstract

The present invention discloses a Fenneropenaeus shrimp low fish meal feed, consisting of the components and the weight percentages that: 15 percent to 23 percent of fish meal, 0 percent to 6 percent of barmy beam pulp, 23 percent to 30 percent of beam pulp, 10 percent to 24 percent of peanut meal, 4 percent to 5percent of beer yeast, 6 percent to 7 percent of shrimp meal, 0 percent to 4 percent of squid meal, 0.2 percent to 0.5 percent of lysine sulphate, 0.09 percent to 0.4 percent of hydroxylv methionine calcium, 0 percent to 0.11 percent of L- threonine, 1 percent to 1.25 percent of fish oil, 0 percent to 1 percent of corn oil, 0 percent to 1 percent of bean oil, 1.5 percent to 2 percent of soyabean lecithin, 17 percent to 23 percent of flour, 0.1 percent of vitamin C phosphate ester, 0.5 percent of choline chloride, 0.2 percent to 0.5 percent of multidimensional premix, 1 percent of phosphate and 0.5 percent to 1 percent of polymineral premix. The feed can not only reduce the use of the fish meal, but also have no bad influence to the growth of the Fenneropenaeus shrimp and the feed efficiency under the comparatively low protein level, thus reducing the feed cost and decreasing the environment pollution in the process of breeding.

Description

technical field [0001] The invention relates to a feed for Litopenaeus vannamei. Background technique [0002] Litopenaeus vannamei is native to the Pacific coast and was introduced to my country in the late 1980s. Litopenaeus vannamei grows fast, has a high meat production rate, survives for a long time out of water, has strong disease resistance, and has a wide range of adaptability to salinity. It is the three best shrimp species with the highest aquaculture production in the world today (Penaeus monodon, One of the Chinese shrimp and Litopenaeus vannamei) is also an important seawater and brackish water cultured shrimp in my country. In 2006, the cultured output of Litopenaeus vannamei in China was 870,000 tons. Litopenaeus vannamei farming is widespread throughout the country and mainly distributed in the southern coastal areas. It is the main source of income for farmers to increase production and income, and has broad market prospects. Fishmeal is the first choice f...
