A fishing tool is provided to enable retrieval of fish from a mineral extraction system. The fishing tool includes a frustoconical member, an outer tubular member, and an inner tubular member. The inner tubular member includes a plurality of receptacles configured to receive a plurality of jaws. Each of the jaws may include teeth on an inward facing surface of the jaw. The outer tubular member may be hydraulically actuated to cause the jaws to move radially inward and engage the fish, enabling removal of the tool and the fish. Systems and methods that include the fishing tool are also provided.
