However, due to the fact that the species of fish and shrimp polyculture are not uniform, domestic academic research on fish and shrimp polyculture feed is rare. and feed nutrition studies are scarce
So far, the feeds for the polyculture model of yellowfin snapper and Penaeus vannamei are mainly common prawn feed and marine fish pellet feed, while the feed developed for the polyculture model of yellowfin snapper and Penaeus vannamei Special feed has not yet been seen on the market

Abstract
The invention discloses a special polyculture compound feed for sparuslatus and penaeus vannamei boone and a preparation method of the special polyculture compound feed. The feed is prepared from the following components in percentage by mass: 6%-10% of white fish meal, 3%-5% of meat and bone meal, 13%-17% of soybean meal, 12%-15% of peanut cakes, 25%-30% of rapeseed meal, 0-1% of selenium-rich yeast, 18%-22% of refined flour, 0-1.5% of kelp powder, 1%-2% of soybean lecithin, 1%-2% of refined fish oil, 1%-2% of calcium dihydrogen phosphate, 2%-4% of a premix, 1%-3% of corn oil and 0-0.5% of isatis tinctoria. The special polyculture compound feed has the beneficial effects that the feed is good in palatability, excellent in food attraction property and easy to digest and absorb and a waste of feed is reduced; the feed is good in stability in water and thus the water quality of a culture water body is less prone to pollution; the raw materials are simple and easily avaiable so that the culture cost is reduced; isatis tinctoria is particularly added so that the non-specific immunity of the sparuslatus and the penaeus vannamei boone is obviously enhanced and the survival rate is improved; and different ecological characteristics of the sparuslatus and the penaeus vannamei boone are sufficiently considered and the win-win of ecological niches of the sparuslatus and the penaeus vannamei boone is guaranteed.
Description
technical field [0001] The invention relates to a compound feed, which belongs to the technical field of compound feed, in particular to a special compound feed for mixed culture of yellowfin sea bream and Penaeus vannamei and a preparation method thereof. Background technique [0002] In recent years, the culture of Penaeus vannamei in my country has entered a period of stable development, but frequent diseases and high mortality have occurred during the breeding process. In view of the above phenomenon, the industry concerned has explored a culture mode of polyculture of fish and shrimp, and obtained better results. [0003] At present, domestic scholars mainly focus on the research on water microbes and water quality regulation for the research on the polyculture model of fish and shrimp. However, due to the fact that the species of fish and shrimp polyculture are not uniform, domestic academic research on fish and shrimp polyculture feed is rare. and feed nutrition res...
