Great Lakes Monitoring
Contaminants in Top Predator Fish
Safety of Fish for Consumption by Wildlife
Goal: Top predator fish will be safe for consumption by all wildlife.
Status: Goal is not met in any Great Lake.
Trends: Contaminants significantly reduced since peaks in the 1970's and are still decreasing in most cases.
Issues: Contaminated sediments and air deposition keep contaminant levels elevated above safe levels for wildlife.
* Lake St. Clair is not sampled for the Great Lakes Fish Monitoring Program
