MILLE LACS LAKE (AP) - Minnesota wildlife officials are imposing another catch-and-release summer for walleyes on popular Mille Lacs Lake.

The restrictions this year include a closure on walleye fishing on Mille Lacs for 21 days, from July 7 to July 27. Anglers can fish for all other species on the east-central Minnesota lake during the 21-day period, including bass, muskies and northerns, but only with artificial bait and lures.

The Minnesota Department of Natural Resources says the catch-and-release restrictions are needed to help rebuild Mille Lacs' struggling walleye population. Catch-and-release regulations were imposed on the premier walleye lake for the first time last season.
