Epinephelus coioides breeding method

Abstract

The invention discloses an epinephelus coioides breeding method and aims to provide an efficient and environment-pollution-free epinephelus coioides breeding method. Adult fishes are safe to eat. Themethod comprises the steps that an indoor culture pond and a biological filter are established, then epinephelus coioides fry with the weight of 50 g are put into the culture pond and fed with bait, breeding conditions are controlled according to the growth needs of the epinephelus coioides fry, and epinephelus coioides grows quickly and is harvested and sold in the market after becoming the adultfishes. The indoor fully-closed culture pond is used for breeding, the fishes cannot escape, and the breeding conditions are controlled according to the growth needs of the epinephelus coioides fry,so that epinephelus coioides grows quickly, and the breeding efficiency is high; the culture pond is communicated with the biological filter, water flow of the culture pond is filtered by the biological filter, then returns to the culture pond and can be recycled, water quality conditions are good, diseases of the fishes are less, environment pollution is avoided, and the adult fishes are safe toeat. The method can be applied to the field of fish breeding.

Description

technical field [0001] The invention relates to a method for cultivating precious seawater fish, in particular to a method for cultivating grouper. Background technique [0002] The oblique-banded grouper (Epinepheluscoioides) is a rare marine treasure, and it is also an important cultured fish species in the southern coastal provinces of my country. It is generally cultured in shallow sea cages. But there are following major problems in this culture method: 1, the pollution of environment causes the deterioration of offshore water quality, makes grouper grow slowly, and disease increases, and culture yield is low; Disaster damage caused the escape of the grouper and affected the breeding output; 3. The workers worked in the open sea for a long time, which was labor-intensive and the breeding efficiency was low; 4. The residual bait, fish excrement and drugs produced during the breeding process were polluted The pollutants directly enter the sea area, causing the offshore e...

Problems solved by technology

But there are following major problems in this culture method: 1, the pollution of environment causes the deterioration of offshore water quality, makes grouper grow slowly, and disease increases, and culture yield is low; Disaster damage caused the escape of the grouper and affected the breeding output; 3. The workers worked in the open sea for a long time, which was labor-intensive and the breeding efficiency was low; 4. The residual bait, fish excrement and drugs produced during the breeding process were polluted The pollutants directly enter the sea area, causing the offshore environment to deteriorate further

Therefore the existing culture method of oblique grouper is inefficient, pollutes the environment and has many adult fish diseases, and is unsafe to eat
