Abstract:

 The current study investigated the effects of temperature on embryonic developing rate and hatching rate of Tylototriton shanjing Nussbaum, Brodie et Yang 1995, and the developmental threshold temperature and effective thermal summation were determined also. The results showed that the speed of the embryonic development was accelerated and the hatchability was raised at 10~30. The hatching rate was linear with the hatching temperature (Y=0.0017X+0.95230), and the grow phase was linear with the hatching temperature (Y=-0.377X+ 24.154) also. However, the most appropriate temperature range was 20~25, and egg deformity and ultimate mortality rates would significantly increase above or below this range. By using linear regression and direct optimization, the calculated developmental threshold temperature and effective thermal summation were 0.58, 68.66·d and 0.46, 69.01 ·d, respectively.
