Sturgeon & Mussels

[Kent]

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

That third picture is a common catch up there.  They have always been the empty shells.  I have caught many on my anchor and also snagged a bunch on my sturgeon hooks.  The ones I have snagged the hook has gone through the shell.
