Are you out on the water enjoying Lake Superior’s legendary fishing? What if your next catch could do even more — not just be a great fight, but help scientists unlock the secrets of one of the lake’s most iconic fish? Trout Unlimited is inviting anglers like you to volunteer for a Coaster Brook Trout genetics project that could shape the future of this special fish.
What Are Coaster Brook Trout — and Why Do They Matter?
Coaster brook trout are a remarkable life-history form of brook trout that spend part of their lives in the vast waters of Lake Superior, growing large and powerful before returning to coastal tributaries to spawn. Once abundant throughout the lakeshore, they declined sharply over the last century due to overharvest and habitat degradation. Now, they’re considered a conservation priority across the Upper Great Lakes.
Conservation partners — including Trout Unlimited — are working hard to restore coaster populations, but there’s still much we don’t know about where they live, how they move, and which tributaries support spawning fish. That’s where you as an angler can make a difference.
How You Can Help with Genetic Research
Trout Unlimited and fisheries agencies are launching a volunteer angler program to collect non-lethal fin clips from brook trout you catch while fishing Lake Superior and its tributaries. These tiny tissue samples are incredibly valuable: genetic analysis can reveal which streams fish were born in and whether fish you catch in the lake are truly coasters or stream-resident brookies.
Why is this important? Genetic data helps researchers:
- Connect individual fish to specific tributaries, revealing where coaster brook trout are spawning.
- Expand our understanding of coaster distribution, especially outside areas regularly sampled by agency crews.
- Provide baseline science that informs recovery strategies and habitat protection actions.
No Special Skills Needed — Just a Love of Fishing
You don’t need to be a biologist to participate. Anglers of all skill levels can volunteer:
- Trout Unlimited will provide simple training and materials.
- You’ll be taught how to take a small, non-harmful fin clip and record basic catch information — training that’s easy to follow and designed with anglers in mind.
- You don’t need to target coasters specifically — just submit samples from brook trout you catch while fishing for any species.
This kind of citizen science helps fill gaps in data where traditional sampling methods struggle, particularly in open water or river mouths where coaster densities are low.
Together We Can Reach a Goal of Hundreds of Samples
Trout Unlimited hopes to collect hundreds of fin clip samples over the coming seasons — a dataset big enough to start answering key questions about coaster ecology and recovery. That goal is only possible with your help out on the water.
Ready to Get Involved?
If you fish Lake Superior or its coastal streams and want to contribute, here’s how to begin:
📧 Contact Jake Lemon, Trout Unlimited Field & Research Manager
— Email: jacob.lemon@tu.org
You’ll receive training details, sampling kits, and support throughout the process. It’s a small time commitment with big impact — both for science and for the future of coaster brook trout in the Great Lakes.
Make your next catch count. Fish. Clip. Contribute. — Join the Coaster Genetics Project and help secure a future for one of Lake Superior’s most legendary native trout.
