Problems solved by technology

However, due to the gap between the breeding environment of giant salamander and its wild habitat environment in these methods, coupled with the slow growth of giant salamander, late sexual maturity, low fertilization rate and survival rate, the proliferation of giant salamander resources and the development of aquaculture are slow.

Embodiment Construction

[0012] The invention relates to a giant salamander imitation ecological breeding method, which comprises the steps of establishment of a giant salamander imitation ecological environment, parent selection, artificial induced labor, artificial insemination, artificial hatching, seedling cultivation and the like. The artificial oxytocin, artificial insemination, artificial hatching and seedling cultivation are all prior art and will not be repeated here. The following emphatically describe in detail the establishment of the giant salamander imitation ecological environment of the present invention and parent selection:

[0013] Establishment of giant salamander imitation ecological environment:

[0014] The ecological environment factors in the main activity areas of giant salamanders in the north source, middle source, south source, You River, Yuan River tributaries and Li River system are investigated. The ecological environment factors are mainly: geography and climate, river...

Abstract

Provided is a bionic breeding method of giant salamanders. The method comprises the steps of building of a bionic environment of the giant salamanders, selection and cultivation of parents, artificial spawning, artificial insemination, artificial incubation and seedling cultivation. The bionic environment of the giant salamanders is built according to the factors, such as ground and climate, river impact factors, cave environment factors and water environment factors, of the natural habitat ecological environment of the giant salamanders, a giant salamander habitat environment factor model is built, a bionic gulley and cave optimal construction parameter system is built according to the model, the optimal survival space of the giant salamanders is determined, the survival environment selection of the giant salamanders is carried out selectively, the giant salamanders return to the original, natural breeding and bait contrast experiments are carried out, a reasonable bait scheme and a needed optimal trophic structure of the bionic breeding of the giant salamanders are determined, the quality of sperms of the parents of giant male salamanders can be improved, and the brood amount of the giant female salamanders is increased.

Description

technical field [0001] The invention relates to an aquatic breeding method, in particular to a method for imitating ecological breeding of giant salamanders. Background technique [0002] The giant salamander is a unique species in China and is a national second-class protected animal. It is distributed in 17 provinces, municipalities and autonomous regions in my country. There are not many studies abroad, and the systematic research on giant salamanders in China began in the 1970s. In 1974, the Salamander Research Institute was established in Sangzhi County, Hunan Province, mainly to carry out resource investigation and artificial breeding research. In 1978, the institute cooperated with the Hunan Provincial Institute of Fishery Sciences to conduct preliminary research on the reproductive physiology and artificial reproduction of giant salamanders. Through artificial induction, salamander seedlings were successfully hatched, but the hatching rate was extremely low. Since ...
