Thanks Curtis,Etranch,and Gander for the replies.
Curtis: Most fish need just about perfect conditions to achieve their maximum age. The areas where these two fish were caught provided them the chance for a long life. Clear fresh water,good current,plenty of grass/reed beds,(cover),plenty of food,deep pockets,and good spawning areas. Not to mention a nice mix of predators and little to none fishing pressure. These fish had a great life for sure.
