Tolerance to saltness and pH in tadpole Rana chensinensis

Abstract

Abstract: Two experiment systems were designed. The results showed under the same water temperature 18.3～20.7 ℃ when pH6.8～7.0, the survival rate of tadpole for 96h was not affected from the salinity 2.0～3.0 g·L^-1, The survival rate of tadpole fell with the increate of the salinity. The salinity TL_m at 24, 48, 72 and 96 h were 8.79, 7.12, 5.64 and 3.83 g·L^-1, respectively. The safety concentration was 1.73 g·L^-1. When the salinity 0.18 g·L^-1, survival rate of tadpole for 96h is not affected from pH4.3～9.3, pH TL_m at 24, 48, 72 and 96h were 10.33, 10.18, 10.08 and 10.02. pH4.3～9.7 and the salinity 1.0～2.0 g·L^-1were all suitable in the survival and growth of tadpole Rana chensinensis.

Key words: Biological invasion, Approach and damage, Prevention measures
