Problems solved by technology

The body color is reddish-brown or yellowish-brown. The flesh of Snapperidae and Silkaceae 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 seedling raising method for white star snapper in an outdoor ecological pond, which comprises the following steps: preparation before breeding, water quality treatment, fingerling disinfection, stocking of fingerlings, and cultivation management, wherein, a disinfectant is scientifically formulated, and before stocking of fingerlings Use fingerling disinfectant for fingerling disinfection. In the three stages of fry growth, the larvae are fed with rotifers, sprinkled with photosynthetic bacteria and gram-positive bacteria, and combined with artificial feed and water flow management, using continuous seawater flow , to maintain the ecosystem of the pond, inhibit the reproduction of other pathogenic bacteria, and achieve the purpose of effectively preventing and controlling the disease of white star snapper.

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 Snapperidae and Silkaceae 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 fa...
