Survival Rate of Freshwater Crustacean, Barytelphusa guerini in Paddy Fields of Nanded District under Influence of Temperature Stress

摘要

Climate change may strongly influence distribution and abundance through changes in survival rate of animals. The freshwater crustacean, Barytelphusa guerini collected from paddy fields of Nanded district. The present paper deals with the survival rate of freshwater crab under temperature stress. The crabs were exposed to six different temperatures ranging from 15, 20, 25, 30, 35 & 40 C. The survival rate was found to be high at lower temperature (15 & 20 C). The survival rate was initiating to reduce at 25 C and became lowest from 30 C.
