Hello Quillback,
I would absolutely be interested in any mussels you found in the lakes you fish. I would be very interested to see any shells you might find in lakes, rivers, resevoirs, ponds, you name it... If its a native freshwater mussel I'm interested. Thanks so much for the offer to help! I hope you drag a few lake mussel shells up (in between big fish catches that is!) when you're out. I look forward to hearing from you.
-Thanks again, Kevin
