Went fishing this morning and while walking along the very low Meramec i found what looked like to me was a Mussel or a big clam partially in the water. ( I know it was not a Zebra Mussel ) It was about 5.5 inches across, anyway i pried it open and cut it in half casted it out and within 2 minutes i caught a couple pound channel. And the other half i caught a big carp. Have any of you ever used this for bait ? And are the good to eat if u find enough of them ? It looked more like a big clam to me. I did a quick search before posting but didnt find any pics of missouri mussels and clam.
