In Salisbury NH huge striped bass reside along the restaurant porches to eat fried clams, french fries, steamers, etc. They are literally no less tame than the ducks at the local pond, like the cuda stories you hear in the tropics.
It's funny, if you throw all three in they will eat the steamer first, then the fried clam, finally the fry gets it too.
A long foam fry imitation? I would do it for a gag, but the restaurant staff would chase me with a kitchen knife for hooking their #1 tourist draw!
I can see how this would be just the ticket in the situation you pointed out.
