Abstract: A fish dimension recording towel and a method of using the fish dimension recording towel are disclosed which are for use in recording the non-weight measurement of a live trophy fish in a catch, photograph, and release fishing program. The fish dimension-recording towel includes a water absorbent fabric having a top side having a non-smooth top surface with a grid portion with grid units having known dimensions thereon. The towel is wetted and placed onto a flat surface with the grid portion exposed. The trophy fish is positioned on the grid portion and two view photographs are taken of the fish on the grid portion of the fish dimension recording towel, one with the fish on its side and the other with the fish rotated about ninety degrees, after which the fish is released. From the printed photographs, the grid units covered by the fish in each of the areas where measurement data is needed may be counted.
