Technical Field
The invention relates to a propagation technology of foreign fishes in China, in particular to a static water stripping artificial propagation method of a large-scale barbel fish.
Background
The large-scale barbel fish is a wide-temperature fish, has various excellent characteristics, is body-building, large in individual, high in growth speed, strong in adaptability, good in clustering property, easy to domesticate and strong in disease resistance, is favored by artificial compound feed, can survive in fresh water and has strong salt and alkali tolerance; the muscle is rich in nutrition, the protein content is more than 20%, and the muscle contains 18 amino acids.
The research on the sinocyclocheilus grahami at home and abroad mainly focuses on the resource investigation aspect of the sinocyclocheilus grahami, the artificial propagation of the sinocyclocheilus grahami is still in the exploration stage, and only the research on the aspects of the demoulding and seedling cultivation of a small amount of ova exists. Under the funding of an introduction project of '948' in the department of agriculture of Heilongjiang aquatic product research in 2003, the large-scale barbel fish is introduced into research in China, through scientific experiments for over ten years, researchers in China master the biological characteristics of artificial breeding of the large-scale barbel fish, but research shows that the large-scale barbel fish is low in egg laying amount which is only one fifth of the carp, the hatching rate and the fry survival rate are not high and only reach 20% -25%, and the large-scale production of fries cannot be realized, and the market demand cannot be met. In order to solve the problem of seedling supply in Jiangsu area, the agricultural science research institute of Sumiton market in 2012 introduces the large-scale barbel fish into Jiangsu province for the first time to develop corresponding research, and carries out artificial trial propagation in 2015, thereby preliminarily knowing the embryonic development law of the large-scale barbel fish and the development characteristics of unfertilized eggs. It can be known from the above that, the artificial propagation technology of the large-scale barbel fry has a small amount of research, but up to now, a set of mature technology system has not been formed, still there are many technical problems that are difficult to solve in the aspects of parent fish cultivation, induced spawning method, fertilized egg hatching and the like, such as the problem that the first sexual maturity time of the backup parent fish is unclear, induced spawning dosage and time are inaccurate, the hatchability of the artificial propagation fry and the survival rate of the fry are lower, which puzzles the large-scale production of the large-scale barbel fry to a great extent, and can not meet the market demand, and the scientists and technicians of the national aquaculture institute of aquatic products are constantly researching and exploring the large-scale barbel artificial propagation technology suitable for the coastal hydrological climate conditions of Jiangsu. The technical problem related to the survival rate of the breeding of the large-scale barbel fish has achieved certain technical achievements, but in practical application, the technical problem which is not overcome still exists.
