Problems solved by technology

The body color is reddish-brown or yellowish-brown. The flesh of snappers and silkworms is fresh and tender, with few diseases and low requirements for bait and environment, especially for salinity. Therefore, the breeding volume continues to increase. Under the influence of various negative factors such as living environment, fish body density, and bait quality brought about by high-density intensive farming, the diseases of white star snapper have also become more serious, among which bacterial diseases and parasitic diseases are more serious. High mortality has become an important factor restricting the development of breeding production

Abstract

The invention provides an efficient artificial breeding method of Lutjanus stellatus in an outdoor ecological pond. The method comprises the following steps: preparation before breeding, water qualitytreatment, fingerling disinfection, fry stocking, and cultivation management, wherein a disinfectant is scientifically prepared, the fingerling disinfectant is used to perform fingerling disinfectionbefore fry stocking, in the three stages of fry growth, rotifer as an initial bait is fed in the larva stage, photosynthetic bacteria and Gram-positive bacteria are sprinkled, the addition of artificial matched feed, and water flow management are combined, a continuous seawater flow is used, an ecosystem of the pond is well maintained, the propagation of other pathogenic bacteria is inhibited, and thereby the purpose of effectively preventing and controlling Lutjanus stellatus diseases is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an efficient artificial seedling raising method for white star snapper in an outdoor ecological pond. Background technique [0002] White star snapper, Lutjanus stellatus, a species of fish in the genus Snapper in the family Snapperidae. The side of the body is flat and the mouth is large. The body color is reddish-brown or yellowish-brown. The flesh of snappers and silkworms is fresh and tender, with few diseases and low requirements for bait and environment, especially for salinity. Therefore, the breeding volume continues to increase. Under the influence of various negative factors such as living environment, fish body density, and bait quality brought about by high-density intensive farming, the diseases of white star snapper have also become more serious, among which bacterial diseases and parasitic diseases are more serious. The high mortality rate has become an important facto...
