Abstract: A fish-activated hook setting assembly for holding a strung fishing pole and automatically setting the hook when a fish strikes the bait affixed thereto. The device is rugged and simple to operate. The device allows the fisherman to cast his line in a normal fashion and thereafter reeve his baited fishing line into an anchoring slot and through a hook in the trigger mechanism and then rest the fishing pole on the device if desired. Upon a strike by a fish, the device in response to the thrust of a fish automatically releases a spring-biased setting arm which pulls the hook into the fish's jaw and secures the catch. The device is readily adaptable to lake fishing from the shore or a boat and to ice fishing.
