A seawater fish black bream overwintering feed

Abstract

The invention belongs to the field of marine fish farming, and particularly relates to a marine fish black porgy overwintering feed. The marine fish black porgy overwintering feed is prepared from the following components in parts by weight: 20-25 parts of white fish powder, 15-20 parts of soybean meal, 15-20 parts of fermented soybean meal, 5-10 parts of shrimp base powder, 15-20 parts of high protein flour, 6-8 parts of fish oil, 6-8 parts of corn oil, 3-5 parts of sleeve-fish ointment, 1-3 parts of carboxymethylcellulose, 1-2 parts of soyabean lecithin, 1-2 parts of sodium dihydrogen phosphate, 0.01-0.50 part of vitamin C, 0.03-0.05 part of vitamin E, 0.5-1 part of multi-vitamins, 0.5-1 part of complex mineral substances, 0.4-0.8 part of choline chloride, 0.4-0.8 part of glycine betaine, 0.01-0.20 part of allicin, 0.01-0.20 part of curcumin and 0.1-0.3 part of a complex enzyme preparation by virtue of mixing. Contents of crude fat and unsaturated fatty acid in the feed disclosed by the invention are moderate, thus the demand on growth of black porgies during overwintering farming is met, the ingestion of the black porgies is favorably promoted, and the survival rate of the black porgies is increased.

Description

technical field [0001] The invention belongs to the field of seawater fish cultivation, and in particular relates to a seawater fish black bream overwintering feed. Background technique [0002] Black sea bream (Acanthopagrusschlegelii) (common scientific name Sparusmacrocephalus), belongs to ray-finned fishes, perciformes, breamidae, genus bream. 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. [0003] Black sea bream is a wide-temperature and wide-haline fish, and its survival salinity is 4.09‰~35.0‰, and its growth adaptability is at a salinity of 10.0‰~30.0‰. The ability to withstand low temperature is stronger than that of red sea bream...
