Novel high-efficiency environment-friendly fish and shrimp polyculture feed

Abstract

The invention discloses a novel high-efficiency environment-friendly fish and shrimp polyculture feed, and aims to provide a fish and shrimp polyculture feed which is easy to prepare and is balanced in nutrition. According to the technical scheme, the novel high-efficiency environment-friendly fish and shrimp polyculture feed comprises the following components: 7-24 percent of bean pulp, 3-8 percent of peanut pulp, 9-15 percent of cotton seed mill, 5-20 percent of rapeseed meal, 1-3.5 percent of cuttlefish paste, 12-17 percent of dried white vinasse, 6-8 percent of rice bran, 15-25 percent of flour, 0.5-1.5 percent of lecithin powder, 2-3 percent of monocalcium phosphate, 1.5-3 percent of bentonite, 0.03 percent of a mildew preventive, 0.03-0.05 percent of allicin, 0.2-0.3 percent of composite vitamin, 0.1 percent of choline chloride, 0.08 percent of potassium chloride, 0.02-0.05 percent of vitamin C, 0.1-0.3 percent of crystal lysine, 1-2 percent of beer yeast, 0.05-0.1 percent of shell element and 1-2 percent of composite mineral. The novel high-efficiency environment-friendly fish and shrimp polyculture feed belongs to the technical field of fish feeds.

Description

technical field [0001] The invention relates to a fish and shrimp mixed feed, in particular to an environment-friendly shrimp mixed feed, belonging to the technical field of fish feed. Background technique [0002] The scientific name of vannamei is Litopenaeus vannamei, also known as white prawn, which belongs to decapod, prawn family and genus Penaeus. It is native to the waters of the Pacific coast of America and is a tropical shrimp. Penaeus vannamei has a fast growth rate, strong adaptability to the environment, low bait requirements, high meat yield, and delicious meat. It was introduced into my country in 1988 and began to be cultured on a large scale along the coast of the country after 2000. By 2011, Penaeus vannamei had accumulatively created economic benefits of more than 100 billion yuan in my country. Although my country's shrimp aquaculture industry has made great progress, with the increasingly serious pollution of seawater, the continuous increase of the sc...

Problems solved by technology

Penaeus vannamei has high nutritional requirements. Generally, mixed herbivorous or omnivorous fish have low nutritional requirements. At present, there are few compound feeds suitable for mixed fish and shrimp. In order to reduce the breeding cost, farmers should Choose low-grade fish feed or duck feed for feeding, which not only affects the production of fish and shrimp in the polyculture pond, but also increases the pollution of the water environment and the possibility of disease outbreaks
