Abstract: The sites of concentration of trace metals cadmium, lead, silver, copper, chromium, manganese and zinc were determined for five species of inshore marine fishes. Generally, zinc and lead accumulate in the gills; copper, cadmium, and zinc accumulate in the liver; and silver, zinc, manganese, chromium, and cadmium concentrate in bone. Flesh doesn't noticeably concentrate any of these elements. Concentration levels with regard to trophic levels were also examined, and it was found that manganese in the liver, and zinc in flesh and bone decrease in concentration with increasing trophic level. Cadmium in the liver may show a direct relationship of concentration with higher trophic levels.
