Coho salmon feed

Abstract

The invention relates to an adult silver salmon feed. The adult silver salmon feed comprises the following components in percentage by weight: 52 to 56 percent of fish meal, 3 to 7 percent of yeast, 6 to 10 percent of puffed soybean, 0.5 to 1.5 percent of phospholipid powder, 13 to 17 percent of flour, 6 to 10 percent of fish oil, 3 to 7 percent of bean oil, 1.5 to 2 percent of alfalfa powder, 0.15 to 0.4 percent of vitamin C, 0.05 to 0.15 percent of compound vitamin B, 0.2 to 0.4 percent of vitamin D, 0.02 to 0.12 percent of carotinoid, 0.15 to 0.35 percent of choline chloride, and 0.2 to 0.4 percent of emulsifying agent. The feed can meet the requirement of adult silver salmon for nutrition, and can improve the growth speed of the adult fish and reduce the death rate of the adult fish.
