Breed conservation and repair technique for Yangtze aquatic animals

Abstract

The invention discloses a breed conservation and repair technique for Yangtze aquatic animals. A specific operation course comprises the following steps of (1) selecting all or part of proper sailing-prohibition Jiajiang-segment waters as construction bases of breed conservation and repair operation places; (2) for each base, allocating corresponding flow velocity resistant ecological conservationfacilities according to the principle that a set of equipment is allocated for one species, and under the traction of a wharf boat, through anchor chain positioning, forming fixed or movable conservation bases; (3) realizing safe controllable diversified rescuing and conservation for the Yangtze aquatic animals through a flow velocity resistant ecological conservation technique; (4) adopting releasing for direct supplementing and repair to avoid secondary hurt through a damage-free enhancement and releasing rescuing technique; and (5) reproducing a plurality of bases, and achieving a fundamental rehabilitation objective through batch conservation, large-scale releasing and supplementing and repair of the quantity of diversified populations of the Yangtze aquatic animals. According to thebreed conservation and repair technique for Yangtze aquatic animals disclosed by the invention, diversified breed conservation and repair until rehabilitation of the Yangtze aquatic animals can be really realized through various measures.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to the species conservation and restoration technology for the Yangtze River finless porpoise represented by the Yangtze River finless porpoise. Background technique [0002] According to scientific research in the 1960s, the Yangtze River aquatic animal species has been maintained at more than 300 species, and the population is quite large, accounting for one-third of my country's freshwater species. It is recognized as a national germplasm gene treasure house. In recent years, scientific investigations by many scientific research institutions and the authority of the Yangtze River Office have revealed that there are only more than 100 species of aquatic animals in the entire Yangtze River Basin, and the population is declining sharply. Among them, the shad is extinct, and the river porpoise is also hard to see. Only the Yangtze River saury still has a very small po...

Problems solved by technology

Although it has played a role in controlling the deterioration of the local regional environment, according to the long-term rescue data of various ambulance stations and the comprehensive data on the increase in natural species conservation and breeding in various finless porpoise nature reserves, it fully shows that the practical significance of the ambulance station needs to be improved. The effect of promoting the increase in wild species conservation and breeding in the finless porpoise nature reserve did not reach the expected normal results

The scientific research on the Yangtze finless porpoise by the Institute of Hydrobiology of the Chinese Academy of Sciences shows that although a breakthrough has been made in artificial intervention to promote the self-propagation of the finless porpoise, there is still no good strategy for increasing the artificial breeding and conservation of the entire Yangtze River Basin on a large scale
