Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).
