Sturgeon & Mussels

[TubeDude]

First two pictures are golden clam (corbicula fluminea)  widespread invasive species. Third picture looks a lot like a marine species. Interesting catch, thanks for sharing

 Thanks for the information. Sure is strange to have such a small clam to be so aggressive.

I doubt it is a matter of aggression.  The clams/mussels lay on the bottom in "beds" of multiple individuals.  Each keeps it's shell partially open while "filter feeding" microorganisms out of the water.  But if a hook drags into the open shell it will quickly close on it.  Just can't picture mussels rising to take a dry fly.
