Feed with function of improving stress resistance of leiocassis longirostris in later aquaculture period

Abstract

The invention discloses feed with a function of improving stress resistance of leiocassis longirostris in a later aquaculture period. The feed is prepared from, by weight, 20-30 parts of cicada pupa powder, 10-30 parts of soybean meal, 5-15 parts of wheat middling powder, 5-15 parts of squid powder, 5-10 parts of red fishmeal, 5-12 parts of algae powder, 10-20 parts of flour, 2-10 parts of modified casein, 2-7 parts of fish oil, 1-3 parts of choline chloride, 1-2 parts of bile acid, 1-5 parts of monocalcium phosphate, 0.1-0.5 part of ferric methionine, 0.1-0.5 part of copper sulfate, 0.1-0.5 part of manganese sulfate, 0.1-0.5 part of zinc methionine, 0.1-0.5 part of magnesium sulfate, 0.5-1 part of arginine, 0.1-0.5 part of glutamic acid, 0.2-0.75 part of betaine, 1-2 parts of vitamins and 1-3 parts of Chinese herbal medicines. The feed has advantages that growth development is promoted, stress resistance and immunity of leiocassis longirostris are improved, and symptoms including surface hyperemia, transverse inclining and mass mortality of leiocassis longirostris from the later aquaculture period to a process of transferring for marketing are avoided.

Description

technical field [0001] The invention relates to the technical field of catfish feed, in particular to a feed for improving the anti-stress ability of catfish in the later stage of breeding. Background technique [0002] The meat of catfish is tender and delicious, rich in nutrition, and the fish fat is thick, which can be processed into precious fish maw. For a long time, people have regarded catfish as a nourishing aquatic product, and it was still a tribute to the imperial court in feudal society. Before the 1970s, the output of catfish was completely dependent on river fishing. Since the 1980s, artificial breeding and breeding technology research on catfish has been carried out, and the technical problems of artificial breeding have been solved. However, during the late stage of catfish breeding to market sales and transshipment, the body surface of catfish is often congested, and serious injuries can be caused. Stress responses such as lateral lodging and mass death of ...
