As someone who’s spent over a decade exploring Michigan’s incredible waterways – from the shores of the Great Lakes to the quiet inland lakes – I’ve always enjoyed the opportunity to supplement a backcountry meal with freshly caught fish. But enjoying this resource responsibly means understanding how to eat safe fish Michigan. It’s okay to eat fish caught in Michigan, absolutely, but it requires being informed about potential contaminants and following state guidelines. This guide will walk you through everything you need to know, from understanding fish advisories to preparing your catch for a healthy and delicious meal.
Michigan’s waters, while beautiful and teeming with life, can contain contaminants like mercury, per- and polyfluoroalkyl substances (PFAS), and polychlorinated biphenyls (PCBs). These contaminants accumulate in fish tissue over time, a process called bioaccumulation. Larger, older, predatory fish tend to have higher levels of these contaminants because they’ve consumed smaller fish that have already accumulated some. The Michigan Department of Health and Human Services (MDHHS) and the Michigan Department of Natural Resources (MDNR) work together to monitor fish and issue consumption advisories to protect public health.

The MDHHS publishes annual fish advisories that detail safe consumption limits for various species caught in specific bodies of water. These advisories are categorized by who is eating the fish – general population, pregnant women, nursing mothers, and children – as these groups are more vulnerable to the effects of contaminants. It’s crucial to check the advisory for the specific water body where you’re fishing. You can find these advisories online, in printed guides available at license retailers, and through the MDNR’s Fish Consumption Advisory app. (MDNR Fish Consumption Advisories)
Advisories typically fall into these categories:
Remember, these are guidelines based on average contaminant levels. Individual fish may vary. Following the most restrictive advisory for your group is always the safest approach.
While advisories vary by location, some species generally have higher contaminant levels than others. Here’s a general overview, but always check the specific advisory for the water body you’re fishing in. It’s okay to eat fish, but choosing wisely is key.
| Species | General Contaminant Concerns | Typical Advisory Status (General) |
|---|---|---|
| Walleye | Mercury | Often limited to 1-2 meals per month |
| Northern Pike | Mercury | Similar to Walleye |
| Largemouth Bass | Mercury, PCBs | Often limited to 1 meal per month or less |
| Yellow Perch | Generally lower contaminant levels | Often more liberal limits, sometimes no advisory |
| Bluegill | Generally lower contaminant levels | Often more liberal limits, sometimes no advisory |
| Lake Trout | Mercury, PCBs | Often limited to 1 meal per month or less, especially in the Great Lakes |
This table is a generalization. For example, Lake Erie Yellow Perch often have very few restrictions, while those from smaller inland lakes might have more. Always consult the official advisories.
Even when following advisories, you can further reduce your exposure to contaminants through proper fish handling and preparation. I’ve learned these techniques over years of fishing and preparing meals in the backcountry.
PFAS are a relatively new concern in Michigan’s fish advisories. Because PFAS are so widespread and persistent, advisories are frequently updated. The MDHHS has issued specific advisories for certain water bodies with known PFAS contamination. Pay close attention to these advisories, as PFAS can have significant health effects.

Beyond consuming fish safely, it’s essential to practice responsible angling and Leave No Trace principles. This ensures the health of Michigan’s waterways for future generations. I always emphasize these principles when leading guided trips.
