I'm also a big fan of clamming and seining crayfish. Naturally, the crayfish could end up smallmouth bait or dinner. The clams go nice with drawn butter or on the hook of a striper rig. If you head to China Town here in New York City, you'll find all kinds of bait species, like spearing, ballyhoo, and butterfish, for sale in the fish market. I can get my head around a lot of these creatures as food. Sometimes bait is downright delicious (think calamari). But I can't fathom eating deep-fried leeches, which according to the clip below from "Dirty Jobs" is not terribly uncommon in the Upper Midwest.
