Fisheries Assessment Starting in Lake Nipissing

Province Gathering Information to Help Assess Walleye Population

Ministry of Natural Resources and Forestry

The Ministry of Natural Resources and Forestry, in partnership with Nipissing First Nation and Dokis First Nation, started a fisheries assessment in Lake Nipissing on Sunday, October 2, 2016.

This annual project, now in its 19th year, will collect important information that will contribute to the management of walleye in Lake Nipissing. Standardized nets are set for 24 hours in randomly chosen locations. Nets will be identified with orange and white buoys labelled 'MNRF'. Boaters should avoid travelling between these buoys.

Fish will be sampled for length, weight, sex, maturity, and age. The data collected from this and other research provide information to guide fisheries management on the lake.

Quick Facts

  • The walleye population in Lake Nipissing is in serious decline, with the current population dominated by young fish.
  • Few fisheries have been studied as long, or as intensively, as the Lake Nipissing walleye fishery.
  • This fisheries survey supports the objectives outlined in the approved Lake Nipissing Fisheries Management Plan.
  • It is an offence under the Fish and Wildlife Conservation Act to interfere or tamper with gillnets set for commercial or scientific use.
