Abstract

The invention discloses a functional compound feed special for turbot. The functional compound feed consists of the following components: Peru fish meal, shrimp shell meal, a beer yeast, corn protein, fermented peanut meal powder, bread powder, calcium dihydrogen phosphate, premixed materials for fish, probiotics, imported fish oil, wheat germs, whey powder and xanthan gum, wherein the probiotics consist of freeze-dried powder of saccharomycetes, bacillus subtilis, tea polysaccharide, dunaliella salina powder, sargassum thunbergii powder and chlorella vulgaris powder in proportions. According to the turbot fed by the feed disclosed by the invention, main delicate flavor materials in muscles can be significantly increased, and the total contents of amino acids, total contents of essential amino-acids, total contents of unsaturated fatty acids and the like are improved to different extents; all indexes such as muscle strength, freshness, fishy smell and taste can be significantly improved; and the immunities of juvenile fish and adult fish can be significantly improved, so that red mouth diseases and albinism of the turbot can be effectively prevented and treated. The feed disclosed by the invention is environmentally-friendly and pollution-free in raw material, and is suitable for large-scale cultivation of the turbot.

Description

technical field [0001] The invention belongs to the field of aquatic feed processing and relates to special compound feed for turbot. Background technique [0002] turbot( Scophthalmus maximus ), Plaiceiformes, Flounderidae, commonly known as "Turbofish", native to the coast of Europe, is a rare bottom-dwelling cold-water seawater fish, it grows fast, the middle part of the body is thick, the viscera is small, and the meat yield High, smooth and tender meat, delicious taste, rich nutrition, has huge breeding and market potential. Introduced into my country in 1992, it has now become an important species of mariculture in the northern coastal areas of my country, and has gradually formed a high-density intensive farming scale. In this intensive farming model, fish feed is the material basis for the survival, growth and reproduction of turbot, which puts higher requirements on fish feed. First of all, fish feed should have a high-quality protein source, with balanced amino ...
