Wisconsin, Minnesota DNRs tag adult walleyes on St. Louis River

The Minnesota and Wisconsin departments of natural resources worked together to tag more than 13,000 adult walleyes on the St. Louis River this spring. The river forms part of the border between the two states. The tagging study is done every five years to determine the adult walleye population on the water body.
“We try to capture as many of the spawning stock as possible,” said Paul Piszczek, fisheries biologist with the Wisconsin DNR. “We try to capture fish from 13 inches to the low 30s to capture the whole range of spawning stock.”
