MNR will be conducting fish management on a lake near you.

Fisheries crews from the Ministry of Natural Resources (MNR) will be on Ontario’s lakes this summer monitoring fish populations, taking water samples and checking for invasive species.

If you’re on a lake that is being monitored and see MNR buoys, please don’t lift the nets or buoys, and avoid recreational activities between and around the buoys. All nets will be clearly


Information gathered through these surveys will be used to help make decisions about managing fisheries, including setting fishing seasons and size limits for anglers.

Five-year monitoring cycle

These lake surveys mark the start of the second five-year cycle to collect information for fisheries management. Approximately 630 lakes will be targeted across Ontario. In the past five- year monitoring cycle, the ministry has sampled approximately 700 lakes.

In southern Ontario, crews will conduct netting surveys on 24 lakes in Fisheries Management Zones 15, 16, 17 and 18 (Bancroft, Midhurst, Parry Sound, and Peterborough Districts).

Lake surveys are done by MNR staff with the support of summer field staff hired from colleges and universities, and local communities. Approximately 1.3 million anglers fish in Ontario each year, spending more than $2.5 billon annually on fisheries-related products and services.
