Culture method for improving quality of euryhaline sea fish

Abstract

The invention relates to a culture method for improving the quality of euryhaline sea fish, which comprises the following steps that: the high-quality health offspring seed is selected to be arranged inside a low-salinity pond to culture after being desalted; the semi-finished product fish 1 to 2 months before reaching the commodity specification is arranged into a sea net cage after being salted to undertake the purification culture; and the feed nutrition is improved, and the environment-friendly additives are added into the feed to prevent the disease and to promote the healthy growth of the cultured fish. All drugs are stopped, so the commodity fish can reach the best color and taste, and the harmful substance and residual drugs inside the fish body can be metabolized to the safe range. The color and the taste of the cultured sea fish are close to that of the natural sea fish, the quality is high, the fish is safe to eat, and the culture method can be used for culturing different euryhaline sea fishes.

Description

technical field [0001] The invention relates to a breeding method for improving the quality of euryhaline seawater fish. Background technique [0002] At present, marine fish culture is mainly based on sea cage culture and pond culture. Cage culture areas are relatively concentrated, with many diseases, difficult to prevent and control, greatly affected by weather and environment, high mortality rate, high risk and high cost, but the product appearance and meat quality of the commercial fish produced are better; pond culture diseases are more prone to Controlling, relatively low impact by weather and environment, high survival rate, low risk and low cost, but the product quality and taste of commercial fish are poor. Although some enterprises and individuals have transformed into intensive farming, there are also some farmers who use unbalanced feed for a long time or blindly pursue growth speed in the breeding process, and overfeed them, resulting in color difference, loos...

Problems solved by technology

Cage culture areas are relatively concentrated, with many diseases, difficult to prevent and control, greatly affected by weather and environment, high mortality rate, high risk and high cost, but the product appearance and meat quality of the commercial fish produced are better; pond culture diseases are more prone to Controlled, relatively less affected by weather and environment, high survival rate, low risk and low cost, but the appearance and taste of commercial fish produced are poor

Although some enterprises and individuals have transformed into intensive farming, there are also some farmers who use unbalanced feed for a long time or blindly pursue growth speed in the breeding process, and overfeed them, resulting in color difference, loose meat, and fat accumulation of commercial fish. Too much and lose the taste that high-end fish should have

During fish disease epidemic seasons, farmers often use drugs for treatment while fishing for the market. The use of fish drugs has not reached the prescribed drug withdrawal period. The quality of aquaculture products lacks effective supervision methods, and there are hidden dangers in the quality and safety of products.
