FRESH-WATER DRUM (Aplodinotus grunniens) This large fish of the Great Lakes and the Mississippi Valley is of considerable importance in the market fisheries, but oflittle interest toanglers except in the South. It is related to the Sea Drum and makes the same drumming sounds. It has heavy grinding teeth like the sea variety and feeds chiefly on Mollusks and Crayfish. Anglers take it best with Crayfish bait.
