Critical thermal minima (CTmin) and lower incipient lethal temperature (LILT) were determined for Penaeus semisulcatus juveniles at combinations of four acclimation temperatures (18, 22, 26 and 30 °C) and four salinity levels (20, 25, 30 and 35 ppt). While the CTmin and LILT of shrimps were not affected significantly by salinity ( P >0.05), a direct relationship was determined between the thermal minima values (CTmin, LILT) and the acclimation temperature ( P <0.05). The acclimation response ratio for the juveniles of P. semisulcatus had an interval of 0.18–0.32 in the current study.
