To establish a uniform bioassay procedure for sublethal concentrations of cadmium in a typical estuarine species, a series of studies was carried out with the grass shrimp Palaemonetes pugio, a common euryhaline estuarine species with a wide distributional range from massachusetts to the Gulf Coast. Survival, molting time and metabolism were the measurement parameters for adult male grass shrimp maintained under different thermal-salinity regimes in either a static or a flow-through system, using CdCl/sub 2/ at different concentration levels as the toxicant. It was concluded that ability to survive environmental stress is lessened by high levels of cadmium that could be present in natural populations, and that respiratory rates are not a reliable indicator of cadmium pollution in P. pugio due to observed variability. Data from a flow-through system is more likely to be applicable to field situations than data based on a static system, and it was felt that P. Pugio is too resistant and tolerant a species to be of value for short term bioassay studies on cadmium. (CAJ)
