Abstract

The invention provides a grouper breeding heat stress resisting method. The method includes following steps of gradient stress resisting domestication, hungry domestication and preparation of an anti-stress agent. After groupers go through anti-stress treatment by the method, live oxidation stress resistance of heat stress resisting of the groupers is enhanced; by improving oxidation resistance ofbodies, oxidization stress of the bodies is reduced, environment adaptability of fishes is improved, and physique of the fishes is improved; the anti-stress agent prepared by the method can improve fish immunity, maintain blood balance and relieve autoimmunity generated by the fishes in a heat stress state.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for resisting heat stress in grouper culture. Background technique [0002] Grouper is the general term for fish in the grouper subfamily (Epinephelinae), which belongs to Osteichthyes, Neopterygii, Acanthopterygii, Perciformes, perch Suborder (Percoidei), Serranidae (Serranidae), are large and medium-sized marine fishes in warm water, widely distributed in tropical and subtropical seas, and mainly distributed in Taiwan Strait and South China Sea in my country. Because of its rapid growth and delicious meat, it is welcomed by farmers and consumers, and the influence of temperature in the breeding process causes the fish body to regulate the activity of its own metabolic enzymes, but when the stress exceeds the self-regulation range, the body produces Excessive active oxygen free radicals, and these free radicals have a damaging effect on the body, causing damage to normal cell...
