Abstract: A fish cleaning device that first kills the fish instantly and humanely and then stabilizes the fish for cleaning. The piercing member used to kill the fish is vertically and horizontally movable. In addition, the piercing member is pivotally and rotatably mounted. In this way the fish can be rotated for skinning and held firmly for gutting by the same piercing member. The device is equipped with a mounting assembly by which it can be firmly and removably mounted to the trunk of a tree, to the ground, or to a worktable or other surface.
