A gripper to hold a fish upright during hook removal has a pliers-like body. This body includes a first member having an outer handle portion joined to an upper jaw portion and a second member having an inner handle portion joined to a lower jaw portion. The lower jaw portion is pivotally carried in an opening between sidewalls of the upper jaw portion. Bottom edges of outer segments of the upper jaw portion sidewalls have tooth-like abrasions. These abrasions mate with like abrasions on a top wall of a swivel element pivotally attached to the lower jaw portion. When the handle portions of the gripper are squeezed togther so that the jaw and swivel element abrasions compressively engage a lower jaw of a fish, downward movement of the swivel element is inhibited by a locking action between complementarily formed offsets on a bottom surface of the swivel element top wall and on the lower jaw portion.
