A method for artificial breeding of sturgeon seedlings

Abstract

The invention discloses a method for artificial breeding of sturgeon fry, which comprises the steps of parental gene bank and file building, parent fish selection and cultivation, artificial egg collection and insemination, fry hatching and cultivation, and the like. By collecting wild sturgeons to establish wild parent gene banks, combined with self-cultivated or purchased artificially cultivated parent gene banks, strain files are established, kinship reorganization is carried out, and sturgeon fry with excellent quality are cultivated. The invention carefully cultivates and domesticates the parent fish used for breeding, promotes the healthy growth and development of the parent fish, and fundamentally guarantees the quality of the offspring sturgeon; carefully controls the hatching environment and fry, ensures the hatching rate and the survival rate of the larvae, and obtains high-quality and healthy adult sturgeon. Sturgeon fry for the sturgeon aquaculture industry, which in turn is beneficial to the development of the artificially cultured sturgeon industry in China.

Description

technical field [0001] The invention relates to a method for artificial breeding of sturgeon fry. [0002] technical background [0003] Sturgeon is an ancient fish and has the reputation of "living fossil". According to reports, there are 27 species and several subspecies of sturgeons in existence. These sturgeons are mainly distributed in eastern Europe, the east coast of North America and the east and west coasts around the North Pacific Ocean. In recent years, due to factors such as environmental pollution and overfishing, the ecosystem of sturgeon has been seriously damaged, and some species of sturgeon are even on the verge of extinction. In order to save the endangered sturgeon and meet the market demand, the artificial breeding sturgeon industry has been promoted. However, at present, my country's artificial breeding technology is not up to standard, and the fry needed by the sturgeon farming industry mainly come from wild sturgeon breeding or fertilized eggs and se...

Problems solved by technology

According to statistics, the demand for fertilized eggs and seedlings in my country's sturgeon aquaculture industry reaches 20 million to 25 million grains (tails) per year. Due to the limited reproduction of wild sturgeon, most of the fertilized eggs and seedlings rely on imports, and their prices are expensive. , The cost is extremely high, which seriously restricts the development of my country's sturgeon artificial breeding industry and the economic benefits of sturgeon farming
