Problems solved by technology

However, in the process of long-term feeding of high-grade feed to ensure that catfish have a good growth advantage, the phenomenon of catfish physique weakening is relatively serious. The main symptoms are loss of appetite, dull body color, and white or yellow liver with many bands. "Piebald", and when encountering a large temperature difference or unstable water quality, the susceptibility of catfish to pathogenic bacteria increases, and sporadic disease often occurs, resulting in increased mortality of catfish and serious economic losses

Abstract

The invention discloses a preparation method of artificial feed for longsnout catfish. The preparation method comprises steps as follows: premix is prepared; fish meal, sargassum thunbergii, snails, krill meal, rapeseed meal, flour, corn flour, peanut shell meal and puffed sweet potato flour are mixed uniformly, crushed until the mixture can pass through a 50-mesh or 60-mesh sieve, and stirred at the speed of 50-150 r / min for 1-2 h; fish oil, olive oil, glycine betaine, an EM (effective microorganism) bacterium liquid, soybean phospholipid and premix are added and continuously stirred at the speed of 120-160 r / min for 30-70 min, water is added until the water content of the system is 15wt%-45wt%, the mixture is stirred uniformly, steam is introduced for curing, granulating and cooling are performed, and the artificial feed for the longsnout catfish is prepared. The product has balanced nutrition and can promote quick growth of the longsnout catfish, the fatality rate of the longsnout catfish is low, and the method is simple and convenient to operate practically.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a method for preparing artificial feed for catfish. Background technique [0002] Catfish is a freshwater fish with the advantages of miscellaneous food habits, fast growth, wide adaptability, and strong disease resistance; its meat is tender, rich in protein and vitamins, and delicious in taste. High-quality fish favored by consumers. At present, most catfish adopt an intensive farming model. High stocking density is the basis for obtaining high breeding returns. Feeding high-grade feed can promote the growth of catfish, shorten the breeding cycle, and achieve early market launch. However, in the process of long-term feeding of high-grade feed to ensure that catfish have a good growth advantage, the phenomenon of catfish physique weakening is relatively serious. The main symptoms are loss of appetite, dull body color, and white or yellow liver with many bands. "Piebald", a...
