195-197Effects of salinity and temperature, and their combined effect on the survival of T. rudolphi were studied. Salinities 2 and 63% were lethal to the animals. With increase in temperature (34 to 43°C) there was a decrease in the time of survival. Survival time was comparatively more at 33°, 35° C and 20 % salinity combinations. They could tolerate low temperatures (16° C) better within a salinity range 20-33%
