The following meal advisories for fish found with elevated levels of chlordane, methylmercury and polychlorinated biphenyls (PCBs) are based primarily on protecting sensitive populations, particularly women of childbearing age, pregnant women, fetuses, nursing mothers and children younger than 15 years of age. All advisories may be overprotective for women beyond childbearing age and males 15 years of age and older.

PLEASE NOTE: THE METHYLMERCURY ADVISORY APPLIES TO PREDATOR FISH – all species of black bass (largemouth, smallmouth and spotted), striped bass, white bass, hybrid striped bass, walleye, sauger, saugeye, flathead catfish, muskellunge and northern pike – IN ALL ILLINOIS WATERS. For more information on mercury in Illinois fish, see the "SPECIAL MERCURY ADVISORY", "Facts About Illinois' Methylmercury Advisory", "Facts About Illinois' Chlordane Advisory" and "Facts About Illinois' Polychlorinated Biphenyls (PCBs) Advisory"
