They allow the shark to swim. A shark with no fins would be unable to swim. Any individual fin provides steering and propulsion depending on exactly which fin you're talking about. The dorsal fin (the one on top of the shark that sticks up above the water in any cartoon about a shark) is mainly for steering.
