| Abstract |
The maximum concentrations of heavy metals (zinc, cadmium, copper, and lead) in otoliths of king mackerel (Scomberomorus cavalla ) were found in very young fish. The apparent decline in content of metals with age and length in king mackerel otoliths most approximated a negative power curve (y = ax-b). The zinc content of otoliths was found to vary significantly between areas in the southeast U.S. and with the age of the fish. |
