Method for artificially reproducing scatophagus argus

Abstract

The invention discloses a method for artificially reproducing scatophagus argus. The method includes rearing female and male parent fish in ecological simulation modes; inducing the maturity of sexualglands of the parent fish by the aid of ambient salinity stimulation and spawning induction hormone injection; carrying out artificial fertilization and incubation; rearing scatophagus argus fry. Themethod has the advantages that scatophagus argus artificial reproduction technical gaps can be filled by the aid of the method, the problem that existing scatophagus argus cannot naturally spawn under artificial culture conditions can be solved by the aid of the method, and excessive dependency of the scatophagus argus culture industry on natural resources can be relieved.

Description

technical field [0001] The invention belongs to the technical field of reproduction biology, and in particular relates to an artificial reproduction method of money fish. Background technique [0002] Money fish (Scatophagus argus), also known as golden drum fish, belongs to Perciformes (Perciformes), Scatophagidae (Scatophagidae), distributed in the Indian Ocean - Pacific Ocean, mainly in the East China Sea and South China Sea in China. It is both ornamental and edible. high-quality economic fish. At present, the fry of goldfish farming all come from wild fish fry caught in natural sea areas. With the continuous development of goldfish farming industry, the demand for fish fry is also increasing, and wild fish fry of goldfish has been overfished. Therefore, the development and application of artificial reproduction technology of money fish can effectively alleviate the excessive dependence of aquaculture on natural resources and help protect wild fishery resources.

Problems solved by technology

In addition, due to the small size of the male fish, it is not easy to obtain food when it is raised with the larger female fish, which directly affects the maturation of its gonads, resulting in the asynchronous development of the male and female gonads, which affects the reproduction of the money fish.

[0006] To sum up, with the continuous expansion of the scale of artificial breeding of money fish, the over
