When contaminant levels, such as mercury and polychlorinated biphenyls (PCBs), are high in fish, consumption advisories (found in the Ontario Ministry of Environment, Conservation and Parks Guide to Eating Fish), may recommend that people and sensitive populations (e.g., children, pregnant women) limit or avoid eating certain sizes and species of fish caught in specific areas of the Detroit River. Researchers from the Great Lakes Institute for Environmental Research at the University of Windsor have been conducting several studies to identify whether consumption advisories for the Remedial Action Plan (RAP) indicator species (walleye, brown bullhead, and smallmouth bass for sensitive populations) are similar to other non-Area of Concern Great Lakes sites.

To provide another line of evidence for the assessment of this beneficial use, the Detroit River Canadian Cleanup (DRCC) continued with their fish consumption survey (launched in 2019) to collect data on what people catch and eat from the Detroit River. So far, majority of anglers (67%) captured in the survey eat the fish they catch from the river (4 to 8 oz of fish per meal about 1 to 4 times per month, on average). The majority of anglers (69%) prefer to pan fry the fish they catch and the most common fish consumed from the Detroit River according to the survey are walleye, yellow perch, smallmouth bass, and white perch.

Do you consume fish from the Detroit River or know someone who does? Take the survey! This information is being gathered by the Detroit River Remedial Action Plan. The RAP is a partnership between government, industry, scientists, environmental organizations, and dedicated citizens that work together to protect and restore the Detroit River ecosystem. The goal of the DRCC is to remove the Detroit River from the list of Canada-U.S. Great Lakes Areas of Concern.
