As one of the main components of the fish fauna in Qinghai-Tibet plateau and playing an important role in the study of fish evolution, it has become the main protective fish in Yunnan province. However, its popula-tion had decreased dramatically in recent years caused by the hydropower station constructed on the Jinsha River and the continuous drought beginning in 2009 in Yunnan province. The popula-tion viability analyses were made by the vortex model, and consequently the population dynamics within the following 100 years were also predicted in T . venusta . Our results suggested that the population had a 54.8% extinct probability in the next 100 years, with an extinct time of 61.4 years under current conditions. The female fecundity, mortality of 0 - 1 age individuals, and catas-trophes were the key factor influencing the long-term population survival. The survival probabil-ity of T . venusta population could rise to 100% within the next 100 years when the current mor-tality of 0 - 1 age individuals decreased by 20% or the frequency and severity of catastrophes to survival decreased by 20%. The carrying capacity of the population habitats had almost no effect on the population survival, even by increasing 50% of the current carrying capacity. Altogether, our study displays that the most effective measures to protect T . venusta population from extinc-tion are enhancing the fishery management, protecting the population habitats, diminishing the occurrence of catastrophes, cutting the mortality of 0 - 1 age individuals, and rising the fecundity of mature individuals.

It belongs to the typical cave animals (troglobites) and is of very important eco-biological significance and sci-research value. Recently, we carried out a preliminary investi-gation into its population size and habitat. The results showed that the population was extremely small (only 15 individuals found in the field surveys of five times) with relatively peculiar habitat, and that it was overly endangered and needed to be conserved.
