Developing eggs of the winter flounder Pseudopleuronectes americanus (Walbaum) were exposed to 9 combinations of cadmium and salinity at 5 and 10C. Overall mean times to 50% hatch ranged from 7.7 days at 10C to 17.9 days at 5C. Mean percentages of total hatches ranged from 50 to 100% for all treatment combinations. Response-surface analyses indicate percentages of viable hatches were generally lowest at 10% S and highest in the 25 to 30% S range. Regression analyses of viable hatch data show that at both temperatures cadmium significantly influenced viable hatch in all experiments. Viable hatch was also significantly influenced by the linear and quadratic effect of salinity in both tests at 5C and in 2 of 3 tests at 10C. The interaction between cadmium and salinity also significantly affected viable hatch at 10C.
