It depends on where they live and the species of fish. Some eat other fish. Parrot fish eat corral. Some fish eat plankton. Sometimes sharks will eat almost any trash left out by uncaring people.

Do you mean 'wild turkeys' that live free in Nature? Wild Turkeys keep eating the live bait before they can actually go catch a fish, It is also difficult for them to hold a fishing rod. If the Turkey would randomly find a fish somewhere he might eat it though if he was hungry enough. But it is not in the natural diet of the turkey to eat fish. A farm Turkey would eat fish if it is fed to him I guess.
