California bass feed for different culture stages and uses of feed

Abstract

The invention discloses California bass feed for different culture stages and uses of the feed. According to California bass culture specifications, culture time, market demands, etc., the Californiabass culture is divided into a seedling stage, a high temperature stage, a rapid growth stage, a wintering stage, a spawning stage and an old fish high temperature stage; and according to the stage division of California bass, combined with the research and development achievements of California bass, the nutrition standards of different stages of California bass are determined. According to the present invention, the problems of unreasonable stage feed standard design in the California bass culture, and mismatch of nutrition standard under different specifications in the California bass culture can be solved.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to California perch feed in different breeding stages and its application. Background technique [0002] The scientific name of California perch (fish) is largemouth perch, which belongs to the order Perciformes, the family Sunfish, and the genus Black Perch. It was introduced into Guangdong, my country in 1983, and was successfully artificially propagated in 1985. The bred fry were successively introduced to Jiangsu, Zhejiang, Breeding in Shanghai, Sichuan, Henan and other places. Because of its strong adaptability, fast growth rate, and tender and delicious meat, it is deeply loved by consumers. It is relatively popular in domestic and foreign markets, and is known as "freshwater grouper". [0003] The California perch breeding process only uses feed with one nutritional level, which does not match the nutritional requirements of California perch at different breeding stage...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defect of mismatching nutritional requirements caused by using only one kind of feed in the whole life cycle of California perch, the primary purpose of the present invention is to provide a kind of feed for California perch in different breeding stages, according to the breeding specifications and breeding time of California perch, the market According to the stage division of California perch breeding, it is divided into seedling period, high temperature period, rapid growth period, overwintering period, spawning period and old fish high temperature period; according to the stage division of California perch and combined with the research and development results of California perch, the different stages of California perch are determined This invention can solve the problem of unreasonable design of feed standard in the stage of California perch breeding and the mismatch of nutritional standards under different specifications in California perch breeding
