Abstract
Changing patterns in survival and metabolic rates were measured during the complete larval development of the estuarine shrimp, Palaemonetes pugio, reared from hatch through metamorphosis in 9 combinations of salinity (7-31 degrees/ooS) and temperature (20-30C), both with and without exposure to a sublethal zinc concentration (0.23 ppm Zn). While early larval stages are extremely tolerant of a broad range of salinities and temperatures, late larval stages, beginning with the second to the last larval stage, are more sensitive to temperature than early larval stages. The most pronounced influence of sublethal zinc exposure on metabolic rates of developing larvae was a depression of the respiratory rates of the first stage, second from the last and the last larval stage under conditions of moderate to high temperatures in high salinities and in low salinity-temperature conditions.
