Problems solved by technology

At present, due to factors such as reproductive biology and morphology of the barbed barb, coupled with the frequent occurrence of diseases under high-density breeding, the extensive use of antibacterial agents will result in drug residues, enhanced drug resistance, and animal immunity. Influences such as the decline in the number of barbs, which restrict the large-scale production of artificial breeding of barbed barbs; in addition, due to the small number of eggs of barbed barbs, only 1 / 15 to 1 / 5 of domestic fish, conventional breeding techniques cannot make up for it. Insufficient fecundity cannot meet the ever-expanding market demand

Abstract

The invention belongs to the technical field of freshwater fish breeding, and discloses an artificial breeding method of spinibarbus hollandi. The artificial breeding method comprises the following steps of parent fish rearing, artificial spawning induction, artificial insemination, fertilized egg hatching and fry rearing. By conducting artificial breeding on the spinibarbus hollandi, the spawning induction rate reaches 80% or above, the fertilization rate reaches 90% or above, the fry survival rate reaches 90% or above, efficient artificial fry rearing of the spinibarbus hollandi is achieved, the production efficiency is improved, and the sustainable development and utilization of the parent fish are ensured.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish breeding, and in particular relates to an artificial breeding method of barbed barb. Background technique [0002] Spinibarbus hollandi belongs to Cypriniformes, Cyprinidae, Barbinae, Spinibarbus, and is mainly distributed in various water systems south of the Yangtze River in my country. It is a famous and high-quality economic fish with high nutritional and medicinal value, which is deeply loved by the market and farmers. However, since the 1980s, due to various human factors, the natural population resources of barbed barb have declined sharply, and it has been difficult to find traces in many rivers of our country. In order to protect this aquatic germplasm resource, the Ministry of Agriculture has successively established more than 10 national-level aquatic germplasm resource protection areas of barbed barb in Guangdong, Guangxi, Jiangxi, Fujian, Hunan, Anhui and other provinces. [...
