Abstract

The invention provides an indoor cement pond artificial fry breeding method for epinephelus tukula. The method comprises the following steps of cement pond treatment, water quality treatment, stockingmanagement and fry breeding management, wherein fry breeding is divided into three stages, different cement ponds are adopted for breeding in each stage, and a good breeding environment is created; in the second and third stages of breeding, water grass planting is combined for cement pond purification, different artificial compound feed additives are fed in each stage, scientific matching is achieved, the growth rule of fry is combined, a wild life mode is simulated, water flow stimulation is conducted, and the fish body quality is enhanced. According to the fry breeding method, the survivalrate is greatly increased, growth and development are fast, and the economic benefits of epinephelus tukula breeding are increased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an indoor cement pond artificial breeding method for black grouper. Background technique [0002] Black-spotted grouper, EpinepheLus tukuLa, also known as blue-bodied large grouper, is a kind of fish belonging to the grouper genus of ray-finned fishes, perciformes, suborder Perciformes. It mainly inhabits rocky reefs, seabed caves and gaps, and coral reefs. It is a carnivorous fish, which is ferocious and cannibalize each other. Especially in the juvenile stage, the small ones are often swallowed by the big ones. Black-spotted grouper has high nutritional value, delicious meat, and is loved by the public. However, the cultivation technology of black-spotted grouper is not mature at present, and the meat quality of the cultivated black-spotted grouper is poor, resulting in low survival rate and low growth rate. The cycle is long and so on. Contents of the invention [0003] In view ...
