Fish can be caught and sold or turned into bait for larger fish. While they are in the water, unless a specific type of Lure is attached, pieces of a fish can be stripped off and eaten by larger fish, leaving bare bones after 3 bites. Normally, bones are worthless, but if you are wearing the Bones Hat, they are worth twice as much as an intact fish. Below is a list of available fish.
