Artificial breeding method of lateolabrax japonicus in northern water areas

Abstract

The invention relates to the technical field of fish culture, in particular to an artificial breeding method of lateolabrax japonicus in northern water areas. The method comprises parent fish selection, parent fish rearing, artificial spawning inducement and insemination and fry rearing. Wild lateolabrax japonicus fries are domesticated and cultured into adult fishes, and high-quality parent fishes are stored by parent fish domestication and screening to become fine breeds for industrialization of the lateolabrax japonicus. Artificially bred fries of the lateolabrax japonicus are provided forthe northern water areas, the limitation of traditional natural conditions is broken through, the natural resources are protected, and the ecological balance is kept.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a method for artificial breeding of perch in northern waters. Background technique [0002] Perch, also known as perch, sea perch, etc., belongs to the order Perciformes, the family Aperidae, and the genus Perch. Mainly distributed in my country, Japan, and the coast of the Korean Peninsula. Sea bass is very popular with ordinary consumers because of its delicious meat, and is one of the traditional species of mariculture in my country and one of the high-quality fish in freshwater culture. Due to its strong adaptability to water temperature and salinity, sea bass has become one of the species that has attracted much attention in the aquaculture industry. It is suitable for breeding in sea and fresh water in different climate zones in the north and south of my country. Seabass farming first started in the south of my country and developed into a large scale. Now it is gra...

Problems solved by technology

However, the full artificial breeding system of sea bass has not been established yet. The main reason is that in the northern waters, the natural breeding season of sea bass is in autumn and winter. At this time, it is difficult to cultivate natural bait, and it is difficult to guarantee labor resources, which makes it difficult to arrange artificial breeding; and , the produced seed needs to survive the winter, and the breeding cost is high

Therefore, there are few farms using artificial seedlings in the northern waters. Generally, natural fish fry are used for domestication and breeding. This not only destroys marine fish resources, violates national fishery regulations, and does not meet the requirements for sustainable and healthy development of aquaculture.

At the same time, due to the small size and low survival rate of naturally caught seedlings, it was difficult to grow commercial fish in the north. Therefore, it is particularly important to vigorously develop artificial breeding of sea bass and cultivate large-sized seedlings.
