I was watching a movie the other day with flathead guide Denny Halgren on catching flatheads. They caught around a 35-40 pound flathead and was talking about the age being around 30-40 years old. I was wondering if anybody knew a good site with these big fishes ages compared to their weight or if you had some personal knowledge on it your self. I was just wondering how old say a 60 pound flathead would be. My guess would be over 50 years. I thought this might inform people of how old these big butes are and the reason I release all big cats.
