Nineteen charges and 18 warnings were made during an enforcement blitz earlier this month by the Ministry of Natural Resources in the Fort Frances area.
Nearly 800 people were checked during the June 11 inspection conducted on Highway 11 in Couchiching First Nations.
Most of them were out-of-town residents.
The charges and warnings were for such things as over-limits, improperly packaged fish and fish that could not be easily identified.
