Walleye populations decrease, DNR working on finding out why

NORTHERN WISCONSIN - Lakes in Northern Wisconsin don't have as many walleye as they did in the past. Adult walleye populations in the ceded territory have declined 2% every year.

Populations of young walleye have declined more than that. DNR scientists think that's because walleye aren't reproducing as much. Reproduction has declined 6% every year.

Researchers are looking at past numbers to find out why.
