Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a special feed for catfish ponds and a preparation method thereof. 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...

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
