Catch-and-release only regulations needed to rebuild Mille Lacs Lake’s walleye population will again be in effect when anglers hit the water on Saturday, May 13. The 2017 walleye season on Mille Lacs is scheduled to run through Monday, Sept. 4.
“Our goal is to have the longest fishing season possible while ensuring the conservation of the lake’s future walleye spawning stock,” said Minnesota DNR Commissioner Tom Landwehr in a news release. “We understand catch and release is a difficult option for anglers who enjoy a fish meal, but we are using everything in our management toolbox to ensure a healthy and plentiful walleye population for future fishing seasons.”
In addition to the catch-and-release regulation, and to help keep the walleye season open on Mille Lacs through Labor Day, the lake will have a 21-day walleye fishing closure from Friday, July 7 to July 27. During that 21-day period, anglers can fish for all other species in Mille Lacs Lake including bass, muskies and northerns but only with artificial bait and lures.
An exception exists for anglers targeting northern pike and muskellunge only, and who don’t possess walleye gear. Those anglers may possess and use live sucker minnows longer than 8 inches when fishing.
The decision to have a 21-day closure period during the walleye season was made after a successful winter season on Mille Lacs drove walleye harvest higher than expected.
“Ice anglers fished more on Mille Lacs in 2017 and caught more and larger walleye than expected,” said Don Pereira, DNR fisheries section chief, in a news release. “As a result, ice fishing this winter accounted for about one-third of the total amount of walleye state anglers can harvest from Mille Lacs in 2017.”
Regulation decisions also were aided by several meetings and consultations with the Mille Lacs Fisheries Advisory Committee. Topics discussed between DNR staff and committee members included catch-and-release only restrictions, season dates, live bait restrictions, and the reason and timing of a temporary summer closure.
“The plan is for this closure to coincide with the hottest part of the summer when released fish are vulnerable to stress,” Pereira explained in the release. “Warm water combined with July’s higher fishing pressure means that more fish die – even those that are caught and returned to the water.”
The tendency for caught fish to die after being released is called hooking mortality, which increases as water temperatures warm. During the last two weeks of July 2016 alone, hooking mortality accounted for more than half of the state’s walleye harvest allocation for the entire open water season.
“These measures will extend the Mille Lacs walleye season as long as possible this summer and protect the younger walleye the lake needs to rebuild its population,” Pereira said.
The state's 2017 walleye allocation is 44,800 pounds. However, during discussions, state and Ojibwe tribal leadership established that the 2017 walleye season will remain open through 12:01 a.m., Sept. 5, provided the state harvest doesn't exceed a conservation cap of 55,800.
Additionally, state and tribal leadership agreed to return to an overage system, through which each party will be required to deduct any harvest above its allocation from a future year’s allocation.
