Shoot,,,I learned what they were when I lived down there on the gulf coast. A finger mullet is a small mullet the length of your finger. Mullet are a fish compared to what carp are here that swims in salt water, Mullet don’t even come close to tasteing good. Those and small crabs, especially softsheels are bait that alot of fish look for to eat. Put eigther of those under a popping cork (a cork thats designed to pop when you pull it quick, it has a recession in the front that looks like a popper here) and throw out as far as you can. If fish are inshore feeding and they see eigther of these baits they will hit it. Red fish and sea trout hit finger mullet all day long.
