Abstract: A fish hook remover for humanely removing a hook from a fish is particularly useful for catch-and-release fishing. The fish hook remover has a handle for a user to manipulate, a hook engagement member, and two rods which connect the handle and the hook engagement member. These connections are located such that the hook remover acts similar to a four-bar linkage. When the handle, forming one side of the four-bar linkage, is rotated one direction, the hook engagement member, forming the opposing side of the four-bar linkage, is rotated the same direction, thereby allowing the user to remotely control the motion of the hook engagement member. The hook engagement member has a channel running through it. An opening in the hook engagement member allows the user to insert the fishing line which is then used as a guide to properly place the fish hook remover. The hook engagement member is slid downward until the fish hook slides into a notch located in the bottom of the hook engagement member.
