Where redear sunfish have been recorded
150 of the 1,288 Michigan lakes on this site with fish records list redear sunfish, across 39 counties, including 1 Great Lakes bay. Tap a dot to open that lake’s depth map.

How we know
- 121lakes where an angler registered one (Master Angler)
- 24lakes where a DNR fisheries survey netted them
- 57lakes the DNR has stocked with this fish; 21 of them are listed on stocking alone, because these fish keep breeding once established
A lake can appear in more than one line. A lake that isn’t listed may still have them: records exist only where someone caught, netted or stocked them.
Inland lakes on this list run from 5 to 19,592 acres (median 174) and from 9 to 123 ft deep (median 40 ft).
When and how big redear sunfish are caught
From 829 Master Angler entries, 1990–2025, from all Michigan waters including the Great Lakes. An entry needs a fish at least 10 in, so these describe big fish that anglers chose to register — where and when people fish, not how many fish a lake holds.
Entries by month
The busiest month is June (33% of entries); 6% come in December–February (lighter bars), mostly through the ice.
Size of registered fish
Half were 10.8 in or less, and 9 in 10 were under 12 in.

How to recognize it
Somewhat larger than a bluegill, with faint vertical bars and a yellow-green belly. The ear flap has a cherry-red edge on males and an orange one on females.

Life in a Michigan lake
Redear forage along the bottom for snails and other shelled animals, which they crush with thick throat teeth. The DNR notes they can also eat invasive quagga mussels. In southern Michigan lakes where they were introduced, redear have been linked to fewer snails in native pumpkinseed diets and lower pumpkinseed numbers.
They nest in colonies in the shallows in spring, like other sunfish, and sometimes hybridize on shared beds.

Rules and eating
Check the rules before you keep fish. Each lake page shows the regulations that apply there, and the Michigan Fishing Guide is the official source. Before eating fish from a particular lake, check Michigan’s Eat Safe Fish guidelines.
