Wow! Hybrid striped bass reproducing in a pond... Now that is pretty much unheard of! What are the details of this pond? Size, substrate, is there a feeder creek? Rainbows reproducing in a pond as well... There has to be a creek or you have a miracle!
I think you could expect 8-10 years as a average life span. White bass are the shorter lived of the two parent species with a 6 year old fish being old. Striped bass the other parent species and are rather long lived with a rare fish reaching 20 plus years of age.
