The wife and I only keep what we want to eat. In a typical year we probably consume about 24 Walleye, 12 Perch, 12 Smallmouth, 6 Lake Trout.
Any large examples get released. We only keep Walleye between 15-18", Smallmouth between 12-16", Perch 11-12", Lake Trout between 16-18". All Northern, Muskie, Crappie and Rock Bass go back.
We fish about 130 days out of every year.
