Nutrition feed for regulating and controlling shelling survival rate of crayfish

Abstract

The invention discloses a nutrition feed for regulating and controlling the shelling survival rate of crayfish. The nutrition feed is prepared from the following raw materials in parts by weight: 200-450 parts of soybean meal, 80-300 parts of rapeseed cakes, 20-80 parts of fish meal, 100-300 parts of rice bran, 100-300 parts of flour, 10-80 parts of soybean oil, 10-30 parts of a mineral premix, 5-20 parts of a vitamin premix, 5-30 parts of phospholipid, 5-20 parts of chitosan oligosaccharide, 5-20 parts of phytase, 20-40 parts of enzymolysis insect powder and 30-70 parts of a fermentation material. The nutrition feed disclosed by the invention has the beneficial effects that the survival rate, the weight gain rate and the feed efficiency of the crayfish fed with the feed disclosed by the invention are notably improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a nutritional feed for regulating the shelling and survival rate of crayfish. Background technique [0002] Crayfish belongs to Crustacea, Crawfishidae, and Procambarus genus. Because of its fresh and tender meat, rich nutrition, and strong adaptability, the aquaculture output has increased year by year. Especially in Hunan, Hubei, Jiangsu and other places, it has become a local aquatic product. One of the leading industries of aquaculture. In recent years, with the development of the Internet economy, the crayfish sales area has covered the whole country. With the rapid development of the crayfish farming industry, farming problems have also been highlighted, especially the deterioration of water quality, frequent diseases, and increased mortality caused by unscientific feed nutrition and feeding have seriously restricted the development of the overall industry. Crayfish a...

AI Technical Summary

Problems solved by technology

At present, research on artificially cultured crayfish at home and abroad mainly focuses on breeding models, breeding techniques, and disease prevention and control, while research on nutrition and feed is rarely reported. At present, the precise preparation of crayfish feed has not been realized in production. Moreover, feeding conventional sinking granular compound feeds for crayfish with poor foraging ability has the problems of low feed utilization and high breeding costs, which is not conducive to the improvement of crayfish breeding benefits.
