A device for measuring the length of a fish that includes fastener and a measuring tape, the fastener including a distal end and a proximal end, opposite to the distal end, and that is attached to a proximal end of the fish, the measuring tape being coupled to the fastener and having a proximal end, a distal end, and a length separating the proximal and distal ends, with the distal end of the measuring tape being located at least at a distal end of the fish to expose a fish length, the measuring tape also having distance indicators along the measuring tape length and extends downward and away from the distal end of the fastener.
