| Abstract |
Juvenile striped bass, M. saxatilis, were exposed to 0 . 5, 2 . 5, and 5 . 0 ppb cadmium as cadmium chloride for 30-90 days and to 1 . 0, 5 . 0, and 10 . 0 ppb mercury as mercuric chloride for 30-120 days. Following the longest exposure to each metal, the fish were allowed to recover for 30 days in running seawater. Gill-tissue respiration, glucose-6-phosphatase, malic enzyme, aspartate aminotransferase, and magnesium activation of AAT were measured. Animals exposed to either metal exhibited changes in gill-tissue respiration. There was no significant difference in enzyme activity during exposure to either metal; however, fish cleared for 30 days following exposure to cadmium exhibited a slight drop in liver AAT and G6PdH. |
