Problems solved by technology

At present, there are few researches on P. yellow-banded trevally at home and abroad, and there is no research on broodstock breeding, seed breeding, and healthy breeding of P. yellow-banded trevally. Therefore, it is urgent to provide a breeding method for P. Environmental regulation ensures the survival rate of broodstock breeding and reproductive regulation and developmental maturity rate, provides high-quality seedlings for industrialized intensive farming, and brings new high value-added aquaculture species to the mariculture industry

Abstract

The invention provides a culture method for Pseudocaranx dentex parents, and relates to the technical field of aquaculture. The culture method comprises the following steps: parent source and selection, culture pond treatment, parent transportation, parent domestication, parent culture and daily management, wherein parent culture comprises water temperature and illumination regulation and control, water ring regulation and control and feed feeding. According to the scheme, factory-like domestication and culture of the Pseudocaranx dentex parents can be achieved, the domestication survival rate and the development maturity rate of the Pseudocaranx dentex parents are increased through parent domestication, periodic regulation and control of culture water temperature, illumination time and the like and reproduction nutrition enrichment, the egg laying rate, the fertilization rate and the hatching rate are increased, factory-like culture of the Pseudocaranx dentex parents is achieved, 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 broodstock breeding method of the yellow-banded trevally, which belongs to the technical field of aquaculture. Background technique [0002] The yellow-banded trevally belongs to the genus of the family Trevallyaceae, commonly known as the giant mackerel, island trevally, and long-breasted trevally. It is called emperor trevally in Hong Kong and Macao. It is a long-distance migratory fish in the middle and upper layers of warm water. Warm waters of the Northwest Pacific Ocean south of Iwate Prefecture, Japan. It has delicious meat, high nutritional value, fast growth and strong disease resistance, and has a huge market potential. It is a precious fish with important economic value and genetic breeding value. It is also one of the candidates for intensive farming in deep and open seas in my country. It occupies an important position in the world's deep blue fishery. At present, t...
