Area of Concern (AOC) Fish Consumption Survey – 2021-2022
The Area of Concern Fish Consumption Surveys helps determine what fish, if any, are being consumed. Whether you consume your catch of the day or not, you are still eligible to complete the survey and win a gift card.
The information collected in this survey will remain confidential and will be used to help guide decisions on the status of the Thunder Bay Area of Concern and to improve the provincial Guide to Eating Ontario Fish.
The information is being gathered by the Remedial Action Plan team (Ontario Ministry of Environment, Conservation and Parks, Ministry of Natural Resources and Forestry, and Environment and Climate Change Canada), that is working with others on monitoring the health of AOCs.
We are not interested in knowing if you have a fishing license and will not be asking any questions related to any laws. Survey responses will be summarized and will not be linked to an individual.
Select a survey of the area you fish:
Thunder Bay Area of Concern
Jackfish Bay Area of Concern
Peninsula Harbour Area of Concern
Invasive species can be extremely problematic to ecosystems, and can affect you too! They can take over habitat, out-compete for food, reproduce rapidly, and completely interrupt food chains. Hundreds of invasive species have infiltrated our lakes, rivers, and forests- causing irreparable damage to fragile habitats and ecosystems.
