The Threat of Invasive Species
Invasive species pose a significant threat to Michigan’s natural resources and economy. These non-native species can cause harm to the environment, economy, and human health. Invasive species can be introduced to new areas through various means, including human activity, such as fishing.
- Boats and waders
- Gear and equipment
- Fish and bait
- Water left in bilges, ballast tanks, and live wells
These invasive species can take many forms, including aquatic plants, mussels, snails, fish, and other animals.
Examples of Invasive Species in Michigan
* Starry stonewort and European frog-bit are two examples of invasive aquatic plants that can choke out habitat and limit fishing access. * New Zealand mudsnails and Didymo (rock snot) are examples of invasive animals that can alter natural food webs in lakes, rivers, and streams. * Zebra mussel larvae and hard-to-see zebra mussel larvae are examples of invasive species that can attach to boats, waders, and gear.
Preventing the Spread of Invasive Species
By taking preventive measures and planning ahead, anglers can help prevent the spread of invasive species.
- Catch and release fishing
- Bait and baitfish
- Boat cleaning and disinfection
- Drain and dry equipment
Effective Decontamination Practices
The Michigan Department of Natural Resources recommends the following effective decontamination practices for trout fishing:
*
| Formula 409 Antibacterial All-Purpose Cleaner | Apply to waders and gear |
| Bleach (1/2 cup to 5 gallons of water) | Rinse with clean water after 20 minutes |
| Virkon Aquatic (20 grams per liter of water) | Rinse with clean water after 20 minutes (see manufacturer’s label for additional guidance) |
Additional Measures for Trout Fishing
For trout fishing, extra measures are needed to prevent the spread of harmful species.
- Remove debris and mud
- Use a chemical disinfectant on waders and gear
- Dry surfaces with a towel
Conclusion
By taking preventive measures and following regulations, anglers can help protect Michigan’s waters and prevent the spread of invasive species. Remember to clean, drain, and dry your boat, trailer, and equipment after each use, and always follow local regulations and guidelines. By working together, we can preserve the tradition of fishing in Michigan while protecting our natural resources for future generations.
“Fishing is not just about catching fish, it’s about preserving the tradition and protecting the environment.”
