The utility model relates to a fish catcher, which comprises two clamping surfaces for clamping fish bodies. The two clamping surfaces can be folded oppositely and are cambered surfaces which are provided with friction surfaces for enhancing friction, and handheld pinching parts are arranged on the backs of the two cambered surfaces. Small hook surfaces with nylon hasps are attached onto the clamping surfaces, and a friction force is greatly enhanced through dense and bent small hooks, so that even catfishes which are difficult to catch cannot escape from the fish catcher.
