Abstract

A functional artificial microparticle feed for grouper is characterized by comprising, by weight, 35-40 parts of white fish meal, 10-15 parts of euphausia superba meal, 10-15 parts of mussel powder, 8-10 parts of squid powder, 2-5 parts of yeast powder, 5-8 parts of hydrolyzed fish protein, 3-6 parts of fish oil, 6-12 parts of alpha-starch, 1-3 parts of sodium alginate, 1-2 parts of inorganic salt mixture, 1-2 parts of vitamin mixture, 1-2 parts of an attractant, 0.1-0.2 part of ethoxyquin, 0.1-0.2 part of an antifungal agent, 1-2 parts of DHA-enriched oil and 5-8 parts of lecithin. The feed has good stability, low melting loss in water, and less pollution on water body, can significantly increase the survival rate and growth performance of the grouper larvae; the feed has high digestion and absorption rate, and can promote the development of the digestive system; and the invention has the advantages of stable sources of raw materials for production, low cost, and simple production process.

Description

technical field [0001] The invention relates to an aquatic feed, in particular to a functional microparticle feed for promoting the development of the digestive system of young grouper fish. Background technique [0002] With the continuous development of intensive and factory farming, my country's marine fish farming industry has developed rapidly, and the aquaculture output has increased year by year, accounting for 70% of the global aquaculture output. However, the problem of seed cultivation still seriously restricts the further development of aquaculture. Seawater fish larvae and juveniles mainly rely on biological bait during the breeding process. However, biological bait has problems such as high price, unstable source, unbalanced nutrition, and easy carrying of pathogenic microorganisms, which not only increases the cost of raising seedlings, but also seriously affects the quantity and quality of seedlings. Therefore, the nutrition and feed of marine larvae and juv...
