Feed capable of preventing fading of spots of channel catfish

Abstract

The invention discloses a feed capable of preventing the fading of spots of channel catfish. The feed capable of preventing the fading of the spots of the channel catfish comprises the following components in percentage by mass: 15.5% of expanded soybean meal, 4.2% of fermented soybean meal, 15.0% of Peruvian fishmeal, 16.0% of rapeseed meal, 15.65% of cottonseed protein, 14.6% of rice bran, 13.0% of wheat middling, 1.8% of monocalcium phosphate, 1.0% of soya-bean oil, 1.5% of phospholipid oil, 1.0% of a premix, 0.02% of vitamin E, 0.03% of vitamin C, 0.05% of complex enzyme, 0.15% of composite bile acid with mass concentration of 20% and 0.5% of traditional Chinese herbal medicine additives, wherein the sum of the mass percentages is 100%. According to the feed capable of preventing the fading of the spots of the channel catfish, the components of the feed are optimized; the composite bile acid and the traditional Chinese herbal medicine components are added according to a certain ratio so as to the effects of improving the capability of the channel catfish body in decomposing and using fat, improving the activity of fatty acid, promoting the emulsification of the fatty acid and the steatolysis effect of pancreas, reducing the content of the cholesterol in the blood, reducing the pressure of the fish body liver for decomposing the fat, activating the activity of tyrosinase, promoting the deposition of melanin and spots and promoting the deposition of the pigment spots and the rapid growth of the channel catfish under the conditions of normal water quality and high-density feeding.

Description

technical field [0001] The invention relates to a feed for aquaculture, in particular to a feed for preventing spot fading of channel catfish, and belongs to the technical field of feed production. Background technique [0002] Channel catfish, also known as American catfish and channel catfish, belongs to Siluriformes, Catfish family, and is a freshwater warm-water fish. Channel catfish are distributed in the central watershed of the United States, southern Canada and parts of the Atlantic coast, and then widely entered the Atlantic coast. It is one of the main freshwater aquaculture species in the United States, and its production exceeds more than half of the total freshwater production in the United States. The fish was introduced into my country in 1984 and was successfully artificially propagated in 1987. Because the fish has the characteristics of wide adaptability, miscellaneous food habits, wide temperature adaptability, strong disease resistance, fast growth, high...

AI Technical Summary

Problems solved by technology

[0003] However, in recent years, in order to pursue breeding benefits, channel catfish often adopt large-scale, high-density and rapid farming in various parts of the country, and high-energy and high-protein nutritional feeds are widely used, which eventually leads to increased excrement, deterioration of water bodies, and increased incidence of disease. At the same time, in channel catfish Discoloration of spots on the body surface of channel catfish, whitening and redness of the whole body, physical decline and death in fish ponds in areas with high fish breeding density have affected the normal growth and market sales of this species, causing serious economic losses to farmers
