Both large and smallmouth bass will eat clams. Usually the will eat the when the clams are "on the move". The clams will expose themselves when they move and bass will bite off the exposed clam. The smallmouth bass is the only freshwater bass with an upper jaw plate designed for cracking the shell of the clam. We have studied bass since 1976 and have recorded clam in stomachs and fecies of both large and smallmouth bass quite regualarly.
bivalve
Absolutely! But cook them very well as there may be e-coli in the water and you want to make sure you kill it all off. Clam chowder is the safest way to eat them.
They eat plankton.
The creature clam is a two-shelled mollusks that is related to the oysters and scallops. The creature is found in the shallow freshwater streams and lakes and in the coastal waters.
I am not sure if they are editable or not but as of 1991 it is illegal in Indian to harvest or disturb freshwater mussels/clam. It is even illegal to pick up an empty shell.
