Provincial fisheries crews will be out on Ontario’s lakes this summer, monitoring lake health and fish populations, and checking for invasive species.

Crews will conduct netting surveys in 24 lakes in Fisheries Management Zone 8 (around Cochrane and Timmins) and 38 lakes in Zone 10 (near Chapleau, Sudbury, Blind River, and Wawa).

Those who are out on a lake that is being monitored and see Ministry of Natural Resources buoys, are asked not to lift the nets or buoys, and avoid recreational activities between and around the buoys. All nets will be clearly marked.

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

These lake surveys are part of a five-year cycle to collect information for fisheries management. Over five years, the ministry will monitor about 1,000 lakes across Ontario. Lake surveys are done by Ministry of Natural Resources staff with the support of summer students hired from local colleges and universities.
