Industrialized fry cultivation method of oval pompano

Abstract

The invention relates to an industrialized fry cultivation method of oval pompano. The method comprises the steps of incubation, transfer of the fries, cultivation of fish larva and juvenile, fodder domestication and the like; according to the method, the fry cultivating processes are all conducted indoors, incubating and raising processes are not influenced by weather, and the yield of raised fries is greatly improved; the method can be used for carrying out directed screening to fed bait, and the fry survival rate in the stage is greatly improved; the requirement of fries on EPA and DHA is ensured, and the fry quality is guaranteed; in the process of industrialized cultivation, the temperature, salinity, dissolved oxygen and other factors in a fry cultivating water body are relatively stable, the aberration rate of the fries is effectively reduced, and the survival rate of the fries is improved; a fry separating sifter is utilized to periodically screen the fries, the self-injury of the fries is reduced, the survival rate of the fries is improved, and meanwhile, the homogeneity of the fries is guaranteed; the method has the advantages that the occupied area for industrialized cultivation of the fries is small, the water demand is less, the sewage discharge is less, and the influence on natural environment is small.

Description

technical field [0001] The invention relates to a method for cultivating seedlings, in particular to a method for cultivating industrialized seedlings of oval pomfret. Background technique [0002] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, is a high-quality edible seawater fish with tender meat, delicious taste, and no intermuscular spines. In the 1980s, Taiwan, China first broke through the breeding technology of oval pomfret, and in the early 1990s, it was introduced to the South China coast of the mainland for domestication. Because of its advantages of ingesting artificial compound feed, suitable for pond culture and deep-water anti-wind and wave cage culture, fast growth and short breeding cycle, the breeding industry of pomfret pomfret has developed rapidly in the past ten years, with an annual output of more than 100,000 tons , has become one of the most important mariculture fishes in the southern coast of my country, and has high economic ...

AI Technical Summary

Problems solved by technology

Due to factors such as poor controllability of breeding conditions, uneven seed quality, and unstable seed production, traditional pond seed cultivation has been unable to meet the market demand for high-quality seed in the pomfret pomfret breeding industry.
