MINNEAPOLIS (AP) - The walleye population in Mille Lacs Lake has fallen to its lowest levels in 40 years, and the lake's larger walleyes may be having trouble finding food.
Officials aren't sure what's happening to Minnesota's most popular walleye fishery. But Department of Natural Resources fisheries research manager Don Pereira told the Star Tribune they're concerned.
Causes could be include:
Pereira says it's too early to say if the DNR might tighten regulations on the lake in east-central Minnesota.
Business owners warn further restrictions could undercut tourism.
DNR representatives and tribal fisheries researchers will discuss the lake next week.
