Abstract:Abstract: In order to evaluate the influence of the tourism disturbance on the species and the resource of prey fish and population size of Chinese giant salamander (CGS, Andrias davidianus), the intensity of disturbance, the number and catch of the prey fish species, and the population size of the CGS under different intensities of tourism disturbance were investigated and analyzed in Zhangjiajie City, Hunan Province. The present species and catch of the prey fish on the sampling localities under high tourism disturbance have been compared with those historic records before tourism development, as well as those areas under low tourism disturbance. A total of 25 species (belonging to 4 orders, 10 families, and 22 genera) of prey fish were found in the sampled habitats of CGS. The number of prey fish in high tourism disturbance areas was greater than those in the areas both before tourism development and under low disturbance (but without statistical significance). According to Jaccard index, the compositional similarities of the prey fish between high and low tourism disturbance areas were generally small. The catch of prey fish in high disturbance areas was also greater than those in low disturbance areas, however, the population size of CGS in high disturbance areas was less than that in the low disturbance areas. Currently, the reasonable and manageable tourism development in Zhangjiajie City had no distinctly negative effect on the prey fish of CGS, but the more intensive disturbance would bring other interferences such as increased noise and decreased dens, thus lowering the population size of CGS.
