Cross breeding method for pelteobagrus fulvidraco and pseudobagrus vachelli

Abstract

The invention discloses a cross breeding method for pelteobagrus fulvidraco and pseudobagrus vachelli. The wild-caught or market pelteobagrus fulvidraco and the wild-caught or market pseudobagrus vachelli are temporarily reared and domesticated to reach the parent fish standard, after artificial injection induced spawning and fertilization, fertilized ova are evenly attached to an incubation net, the fertilized ova are incubated in a cellular incubation pool through micro-flow water, and then crossbred fry are obtained. The pelteobagrus fulvidraco and pseudobagrus vachelli artificially-crossbred fry which are quick in growth, high in stress resistance and better in meat quality can be obtained, and the cross breeding method has significance in meeting the living needs of people and increasing freshwater aquaculture new varieties.

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),...

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
