MNRF: Broadscale Monitoring Program

The Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) is responsible for monitoring the abundance and health of fish populations in selected lakes across Ontario. Ministry science crews will collect information on fish species, take water samples, and check for invasive species in this lake and approximately 150 other lakes across the province

Biological data are collected by our science crews and provide MNRF biologists with valuable information about abundance, age structure, mortality, and maturity of the types of fish in the lake. This information is used to evaluate the health of fish populations in the lake and make management decisions.

The number of fish caught and sampled represents a very small percentage of the total population in the lake. As resource managers responsible for the sustainability of these populations, we are sensitive to the number of fish collected, but strongly believe this information is necessary to responsibly manage this resource.
It is important for your safety and for the integrity of our data that these nets are not disturbed.
