Title: Zinc and cadmium residues in striped bass from Cherokee, Norris, and Watts Bar reservoirs

Abstract

Zinc and cadmium concentrations in muscle, liver, and kidney were measured in striped bass (Morone saxatilis) from Cherokee, Norris, and Watts Bar reservoirs in East Tennessee to determine if these metals had contributed to fish kills observed in Cherokee during the 1970's. The range of mean concentrations of zinc from collections of Cherokee striped bass (muscle 11-14, liver 98-106, kidney 88-105 mg Zn/kg dry weight) were comparable to ranges in fish from Norris and Watts Bar (muscle 12-13, liver 83-132, kidney 96-108 mg/kg dry weight). With the exception of concentrations in the kidneys of one collection, cadmium residues from Cherokee striped bass (muscle 0.02-0.09, liver 0.3-0.7, kidney 0.2-4.0 mg Cd/kg dry weight) were also similar to residues from Norris and Watts Bar fish (muscle 0.05-0.13, liver 0.3-2.1, kidney 0.3-0.5 mg Cd/kg dry weight). There were significant differences in tissue residues among seasons (summer 1979, spring 1980, summer 1980) in Cherokee Reservoir, as well as significant differences among the three reservoirs (Cherokee, Norris, Watts Bar) during the same season (spring 1980). All concentrations, however, were well below those reported for fish exposed to the maximum non-harmful concentrations of zinc and the lowest potentially harmful concentration of cadmium and moreover, were withinmore » the range typically reported for fish tissues. It is, therefore, believed that in at least the last two years, zinc and cadmium in the tissues of striped bass from Cherokee Reservoir have not been harmful to the fish.« less
