Michigan is muskellunge country — Lake St. Clair is widely regarded as the best muskie fishery in North America. Harvest is capped at one fish per angler per license year and every kept muskie must be registered within 24 hours, so the 42-inch minimum plus a year-round catch-and-immediate-release season make this a release-first fishery.
