Depends on the fish. The tails of many fish are great fried. It's just another crunchy item. Salmon skin is also tasty as long as you get it crisp when cooking.

Mahi skin is kind of thick and chewy so I usually throw that away (or into the marsh for the local critters to eat). Most of the bass type fish skins are also tasty. Heads are harder to deal with unless you want to make your own stock. I grew up on the coast, catching, cleaning, and cooking my own fish all the time. I know not everyone has those experiences.
