Cooler weather, late walleye spawning for this year's fishing opener

Walleye-egg squeezers
Mike Knapp works with a female walleye at the DNR egg take station on the Pine River north of Pequot Lakes, Minn., on April 25, 2014. The DNR collects eggs from fish caught in the trap. The fish are hatched and raised before being released into lakes throughout the area.
