Broad-scale fisheries monitoring activities are being done by Biodiversity and Monitoring Section staff across Ontario this year.

In addition to Broad-scale fisheries monitoring Ministry of Northern Development Mines, Natural Resources and Forestry (NDMNRF) science crews will be conducting other fisheries monitoring activities on specific lakes. For full details click on “Read More”

Monitoring on these lakes will include:

Winnipeg River– summer recreational angler survey (creel)

Lake Nipissing – summer and winter recreational angler surveys (creels), and Fall Walleye Index Netting

Tri-Lakes (Pigeon Lake, Chemong Lake, and Buckhorn Lake) – summer recreational angler survey (creel)

Ottawa River (Holden Lake, Lac Deschenes) – netting

-Lake Simcoe – netting

For recreational angler surveys (creels), Ministry staff will be counting and interviewing anglers, recording the number of fish kept and released and hours fished. Biological information will also be collected from fish that anglers keep, including lengths and weights. This allows biologists to determine the average size of fish harvested. The information collected from this survey will be used to estimate the harvest of sportfish and angling pressure and compare the results to historical angler surveys. While angler participation in the survey is voluntary, NDMNRF appreciates all information shared with field staff.

From approximately June 13 to September 14, 2022 NDMNRF science crews will be conducting netting on the above listed lakes (approx. 56 lakes) will be assessed this summer in the Northeast Region. NDMNRF science field crews will collect information on fish species, take water samples, and check for invasive species. Netting will take five to eight days to complete on each waterbody.

Notices will be posted at various locations like public boat launches and retails stores located on the lake during this time. All nets will be clearly marked with the Ontario logo and will be checked daily then moved to new locations. Please don’t lift the nets or buoys and avoid recreational activities between and around the buoys.
