Culture method of trachidermus fasciatus

Abstract

The invention relates to a culture method of trachidermus fasciatus, which belongs to the technical field of fish culture and comprises the following steps of: fry desalination and cultivation; culture pond preparation; pond culture; culture management; pond-separating strengthened fattening; and artificial maturity acceleration. By adopting steps provided by the technical scheme, the invention is not harsh, can expand culture in large areas, has the advantages of ideal operability and applicability, the survival rate in indoor cement pond cultivation up to more than 85 percent and the survival rate in culture pond culture up to more than 35 percent, and can be successfully abutted with an artificial fry propagation technology to form a complete industrial chain.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a method for cultivating Songjiang perch. Background technique [0002] Songjiang perch (Trachidermus fasciatus) belongs to Scorpaeniformes, Cottidae, and Trachidermus. Songjiang perch has a wide distribution area in history. It is a common fish in the Bohai Sea, Yellow Sea, East China Sea coast and adjacent freshwater waters. It is known as one of the "Four Famous Fishes in China" for its delicious meat and changeable body shape. However, with the development of the economy, due to the increasing disturbance to the environment, the distribution area of ​​this species in our country has shrunk sharply and even is on the verge of extinction, so it has been listed as a national second-class protected animal. [0003] Songjiang perch is an annual fish, and the seedlings bred in the same year can reach sexual maturity in the same year, and most of the broodstock aft...

Problems solved by technology

At present, artificial propagation of Songjiang perch and early seed cultivation have made some breakthroughs, such as invention patent application publication number CN1915007A (production method of Songjiang perch summer flower seed) and CN101138327A (Songjiang perch desalination fish fingerling cultivation method) and CN1012333B (Songjiang perch desalination fish fingerling cultivation method) and CN1012333B (Songjiang perch) Artificial breeding methods), but artificial breeding has not yet achieved satisfactory breakthroughs

However, as the industry knows, artificial breeding is precisely the key to protecting the resources of Songjiang perch, because only through reasonable breeding methods can the precious species of Songjiang perch be truly saved and the resources restored, otherwise even if the early reproduction and seedlings If the breeding technology of the species reaches the ultimate maturity, it will still lead to the embarrassing ending that the success will fall short due to the inability to form a complete industrial chain.
