Fisheries crews from the Ministry of Natural Resources and Forestry 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 buoys showing the Ontario logo, please don’t lift the nets or buoys, and avoid recreational activities between and around the buoys. All nets will be clearly marked.
During the lake surveys staff:
- Sample fish to check for abundance, length, weight, age and contaminants
- Check water temperature, clarity and oxygen levels
- Look for invasive species such as spiny waterflea and rusty crayfish in some lakes. Information gathered through these surveys will be used to help make decisions about managing fisheries, including setting seasons and size limits for anglers.

Approximately 160 lakes will be targeted this summer across Ontario. In the northeast, crews will conduct netting surveys and water samples in the following Fisheries Management Zones (FMZs):
- FMZ 7 (near Wawa) – two lakes
- FMZ 8 (near Timmins, Chapleau, Cochrane, Hearst and Kirkland Lake) – 27 lakes
- FMZ 10 (near Chapleau, Sudbury, Timmins and Sault Ste. Marie) – 37 lakes
- FMZ 11 (near North Bay) – one lake
- FMZ 12 (near North Bay) – two lakes.
Netting begins in the northeast on May 28. About 1.3 million anglers fish in Ontario each year, spending more than $2.5 billion annually on fisheries-related products and services.
