Abstract

The invention discloses a breeding method for buffalo perches. The breeding method comprises the following steps that parent fishes are selected, wherein a perch serves as a female parent, and a big mouth buffalo fish serves as a male parent; the parent fishes are cultured; gametes are obtained; incubation and fry culture are performed. The buffalo perches cultured based on the breeding method are large in size, have much flesh, are high in disease resistance and cold resistance, grow fast and are easy to catch.

Description

Technical field: [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating crimson perch. Background technique: [0002] Perch, also known as flower perch, village flower, perch board, four-rib fish, etc., is one of the freshwater fish with the most varieties, the widest distribution, the longest breeding history and the highest yield. It has strong tolerance to the environment and can Survive in low temperature and dissolved oxygen. However, with the increase of breeding time, the evolution of perch is extremely slow, and the quality of the species has also degraded to a certain extent, which greatly restricts the cultivation of perch. Invention content: [0003] In order to solve the above problems, the invention provides a method for cultivating crimson perch. The crimson perch cultivated by the method provided by the invention is large in size, rich in meat, strong in disease resistance and cold resistance, relative...
