Lake Michigan supports a diverse community of carnivorous (piscivorous) fish, plus reptiles that prey on them.
| Species | Status | Notes |
|---|---|---|
| Lake Trout | Native (recovering) | Apex predator; deep, cold water. |
| Chinook (King) Salmon | Introduced (Pacific) | Major sport fishery; die after spawn. |
| Coho Salmon | Introduced | Smaller, acrobatic. |
| Brown Trout | Introduced (Europe) | Shore/near-shore; tolerant. |
| Steelhead (Rainbow Trout) | Introduced (anadromous) | Lake-run; prized sport fish. |
| Smallmouth Bass | Native/Introduced | Rocky structure; aggressive. |
| Largemouth Bass | Introduced | Weedy bays, harbors. |
| Northern Pike | Native | Weedy shallows; ambush. |
| Muskellunge (Musky) | Native/Stocked | Apex; "fish of 10,000 casts." |
| Walleye | Native/Stocked | Low light; excellent eating. |
| Yellow Perch | Native | Small predator; key forage & panfish. |
| White Bass | Native | Schooling; spring runs. |
| Striped Bass | Introduced (hybrid w/ white bass) | Open water; powerful. |
| Burbot (Lawyer/Eelpout) | Native | Cold, deep; winter spawner. |

| Flathead Catfish | Native | Large; live prey only. |
| Bullhead Catfish | Native | Small; tolerant. |
Invasive species (alewife, round goby, zebra/quagga mussels) have reshaped the food web. Salmon stocking is managed to balance predator-prey ratios. Lake trout restoration is a major success story.
