Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a healthy and pollution-free silver carp feed. Background technique [0002] The nutritional content of the feed can not only affect the normal growth of fish, but also affect the immune and disease resistance of fish. Good nutritional quality and physical properties of feed are the key to fish farming technology to achieve production and economic goals. At present, with the popularity of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low, which is very unfavorable to the growth of silver carp. It is a high-quality fish feed with reasonable ratio and relatively uniform nutrition. The feed is rich in nutrition and rich in fragrance, which can meet the nutritional needs of silver carp during the growth period, and can increase the growth rate of sil...

Problems solved by technology

At present, with the popularity of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low, which is very unfavorable to the growth of silver carp. It is a high-quality fish feed with reasonable ratio and relatively uniform nutrition. The feed is rich in nutrition and rich in fragrance, which can meet the nutritional needs of silver carp during the growth period, and can increase the growth rate of silver carp by about 30%~40%. Significantly larger body size, delicious meat, high survival rate
