Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations How Old will Georgia Giant Hybrids Get?

Rock creek they can reproduce but you don't want the offspring. There is a bunch here on the subject just do a search for Georgia Giant.

Very little is known about the fish as it is proprietary and no science is released by the owner. Assuming they are like a HBG then in your location 6-8 years could be expected with no problem.

See this one for example http://www.pondboss.com/forums/ubbthreads.php?ubb=showflat&Number=169112&fpart=1
