The use of copper may prove feasible for the control of catastrophic fish mortalities associated with blooms of Gymnodinium brevis. Prerequisite is knowledge of the effect that relatively high concentrations of copper may have on the marine community as a whole. In this study the effect of copper on the growth of 145 marine bacteria was measured. All of the bacteria grew in a medium containing copper in concentrations up to 0.25 mg/L. This concentration was compared to the in vivo (0.2 mg/L) and in vitro (0.1 mg/L) lethal dose of copper for G. brevis. In addition, the growth of approximately 4 per cent of the bacteria was stimulated by this concentration of copper.
