Problems solved by technology

flower tailed hawk High nutritional value, difficult to catch, has a great market demand, but at present the flower-tailed hawk There are few researches on broodstock breeding in China, and most of the artificially cultured fry are caught in the wild. The immaturity of artificial breeding technology has seriously restricted the Factory scale development of farming

Abstract

The invention provides an eagle coreana parent fish rearing method, and belongs to the technical field of aquaculture. Comprising the following steps of parent source and selection, parent transportation, parent domestication, parent cultivation, reproduction regulation and management after parent spawning, and reproduction regulation comprises nutrient enrichment and collection and incubation of fertilized eggs. According to the scheme, factory-like domestication and cultivation of the eagle paternal fish can be achieved, the domestication survival rate and the development maturity rate of the eagle paternal fish are increased through periodic regulation and control of cultivation water temperature, illumination intensity and the like and reproduction nutrition enrichment, then the egg laying rate, the fertilization rate and the hatching rate are increased, factory-like artificial breeding of the eagle paternal fish is achieved, and the breeding cost is reduced. And a new high-added-value culture variety is brought to the mariculture industry.

Description

technical field [0001] The invention relates to a broodstock breeding method, in particular to a flower-tailed hawk A broodstock breeding method belongs to the technical field of aquaculture.
