Problems solved by technology
However, in actual production, they also have certain production disadvantages: yellow catfish has strong adaptability to the environment, and its body color is bright. In recent years, the market has gradually become optimistic, but its commodity specifications are small, and it cannot escape the category of small fish; Jianghuang catfish is the largest species in the genus of yellow catfish (the largest individual can reach 1850 grams), but because its body color is mostly off-white, it is not easy to accept in the market habits of some regions

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the embodiments. The following descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention to other forms. Changes to equivalent embodiments with equivalent changes. Any simple modifications or equivalent changes made to the following embodiments according to the technical essence of the present invention without departing from the solution content of the present invention fall within the protection scope of the present invention.
[0017] The hybrid breeding method of yellow catfish and river yellow catfish is specifically completed through the following steps:
[0018] 1) Breeding and selection of parents: the brood fish come from wild catch or market, and after one year of temporary breeding and domestication, they reach the standard of brood fish. The size of the broodstock is 30-40cm for male fish, and the weight is 500-1000g / tail...

The invention discloses a hybrid breeding method for pelteobagrus fulvidraco and pseudobagrus vachelli. By temporarily domesticating the pelteobagrus fulvidraco and the pseudobagrus vachelli from wildcatch or market to meet the standard of parent fish, and fertilized eggs are evenly adhered to a hatching net after artificial injection of labor and indoctrination and incubated in a 'beehive type'hatching pool for micro water hatching to obtain hybrid fish species. With the method, artificial hybrid fingerling of the pelteobagrus fulvidraco and pseudobagrus vachelli with fast growth, strong stress resistance and excellent meat quality can be obtained, and the method is of great significance for meeting the needs of people and increasing new varieties of fresh water culture.
Description
technical field [0001] The invention belongs to the technical field of freshwater fish hybrid breeding, and in particular relates to a hybrid breeding method of yellow catfish and river yellow catfish. Background technique [0002] Most of the fishes of the family Acididae are tender in meat, delicious in taste and rich in nutrition. They are favored by consumers and become the new darling of freshwater fish farming. The river yellow catfish and yellow catfish are species with development potential among the fishes of the family Scorpidae. However, in actual production, they also have certain production disadvantages: yellow catfish has strong adaptability to the environment, and its body color is bright. In recent years, the market has gradually become optimistic, but its commodity specifications are small, and it cannot escape the category of small fish; Jianghuang catfish is the largest species in the genus of yellow catfish (the largest individual can reach 1850 grams),...
