Abstract

The invention discloses a pollution-free freshwater perch breeding method. The breeding method comprises the following steps of S1, preparing a culture pond; S2, selecting parent perches; and S3, performing artificial spawning induction. The invention provides the scientific and effective practice method for the artificial breeding and culture method of perches and carps, solves the problems of low yield and high cost of adult fishes due to low breeding means of existing farmers, reduces the cost required by fish breeding, improves the survival rate of fish breeding, and meanwhile, improves the prospect of fish breeding.

Description

technical field [0001] The invention relates to the technical field of perch breeding, in particular to a breeding method for pollution-free freshwater perch. Background technique [0002] Perch body is long and flat, the lower jaw is longer than the upper jaw, and the flesh is firm and garlic-like. It grows and fattenes in fresh water, inhabits the bottom of clear water, lurks during the day, and is active at night, preying on shrimps and small fish. It is distributed in the western part of the Pacific Ocean, and it is produced along the coast of China, especially in the Yellow Sea and Bohai Sea. [0003] Sea bass is one of the common economic fish. Its meat is delicious, rich in protein, vitamins, niacin, phosphorus, iron and other nutrients. Perch has the characteristics of fast growth, wide adaptability, and strong disease resistance. It naturally feeds on small fish and shrimp, and artificial breeding has high economic benefits. [0004] Ubiquity in the prior art has...
