Fish were euthanized with an overdose of 150 mg/L MS-222. Waterborne Zn exposure appeared to stimulate gowth while dietary Zn exposure inhibited growth. Fish on the high Zn diet were significantly smaller that low water Zn treated fish on days 14 and 28. Whole body Zn concentrations increased significantly with time and Zn exposure. Zn concentrations in high Zn diet were significantly higher than respective controls on days 28 and 40.
