Tumors in fish from the Detroit River,erall, 8.2 percent of the fish examined had oral/dermal lesions and 10.1 percent had liver lesions. Liver and skin tumors were found to be age-related in bullheads and size-related in walleye. B ased on the fish surveyed, the incidence of tumors in fish from the Detroit River was similar to that observed in other chemically contaminated waterways.
