Feed for litopenaeus vannamei

Abstract

The invention discloses a feed for litopenaeus vannamei, which comprises the following nutrition compositions by mass percent: 25-35% of proteins, 4-9% of fat, 7-12% of ash contents, 40-55% of carbohydrates and 3-11% of water. The feed can meet the nutrient requirement of litopenaeus vannamei for best growth, and effectively solves the traditional problems of high protein level of a compound feedand severe environmental pollution in the process of culturing litopenaeus vannamei; the industrial profit is increased, and the pollution and the damage to a water environment in the process of culturing are reduced; and the sustainable development of litopenaeus vannamei culturing industry is realized.

Description

technical field [0001] The invention relates to the field of prawn feed, in particular to a feed for Litopenaeus vannamei with low protein and balanced amino acid patterns. Background technique [0002] Litopenaeus vannamei is an important marine and brackish water cultured shrimp in my country. Because of its delicious meat, high nutritional value and large economic benefits, it has broad market prospects. However, as the prices of global energy and food resources continue to soar in recent years, the high-density and intensive farming of Litopenaeus vannamei has been severely restricted. On the one hand, it is because the fishmeal content in the current feed is too high, resulting in high farming costs and low profits; on the other hand, because the protein content in the feed is too high, the ammonia nitrogen and phosphorus content discharged into the breeding water exceeds the standard, resulting in huge damage to the water environment. Pollution and destruction are no...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a vannamei according to the disadvantages that the protein content and fish meal content in the existing Litopenaeus vannamei feed are too high, resulting in high breeding costs, excessive ammonia nitrogen discharge and phosphorus content, and causing huge pollution of the water environment. Litopenaeus feed, the feed contains low protein level and balanced amino acid pattern, which reduces the pollution to the breeding water

The use of this feed effectively solves the problems of high protein level and serious environmental pollution in the current Litopenaeus vannamei culture process, not only improves the industrial profit, but also reduces the pollution and damage to the water environment during the culture process, and realizes Sustainable Development of Litopenaeus vannamei Aquaculture Industry
