Sparus macrocephalus feedstuff with low fish meal protein content

Abstract

The invention relates to a sparus macrocephalus feedstuff with low fish meal protein content. The costs of existing sparus macrocephalus artificial compound feedstuffs are high, and the feedstuffs are likely to cause sea water pollution. The dry material of the sparus macrocephalus feedstuff provided by the invention is a mixture comprising components of, by weight: 20 to 30% of whitefish meal, 18 to 25% of soy protein concentrate, 5 to 10% of soybean meal, 10 to 15% of shrimp-based powder, 15 to 24% of gluten flour, 3 to 5% of fish oil, 3 to 5% of corn oil, 1 to 2% of soybean phospholipids, 1 to 2% of sodium dihydrogen phosphate, 0.5 to 1% of vitamin complex, 0.5 to 1% of composite minerals, 0.4 to 0.8% of chloride choline, 0.4 to 0.8% of betaine, and 0.1 to 0.3% of a composite enzyme preparation. The feedstuff provided by the invention is advantaged in high nutritive value, good luring effect, low feed coefficient, high efficiency, environment friendliness, and low cost.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a black snapper feed low in fishmeal protein. Background technique [0002] black sea bream ( Acanthopagrus schlegelii ) (common scientific name Sparus macrocephalus ), belonging to ray-finned fishes, perciformes, breamidae, and bream genus. Black sea bream is a rare and valuable economic marine fish cultured in the southeast coast of my country and Japan, South Korea, Taiwan, Southeast Asia and other countries and regions. The adult fish has delicious meat and high nutritional value, and is welcomed by consumers at home and abroad. It is one of the most potential targets for intensive marine fish farming in the future. Black sea bream farming is mainly fed with low-value fish and shrimp-based surimi feed, which has a high feed coefficient and pollutes water quality, resulting in the waste of limited protein resources and the spread of diseases. At present, the existing artific...

Black sea bream farming mainly feeds low-value fish and shrimp-based surimi feed, which has a high feed coefficient and pollutes water quality, resulting in the waste of limited protein resources and the spread of diseases

At present, the existing artificial compound feed for black sea bream, its main feed protein raw material is fish meal whose resources are more and more scarce and the market price is rising year by year. Aquaculture is at odds
