Hey Bob Just a thought about your blog topic from a newbie. genetics has got to be high on the priorities for fish we stock because without them then the fish never have the potential to become large. But perhaps more important based on some of your comments about the first stockings doing the best would be the conservation of energy those fish enjoyed by being the top dog there whole life. Never having to waste energy running and hiding, no stress worrying about being someone elses lunch. All they have to do is eat and get big. Perhaps that might be "the missing link". No other fish put in after the original stocking would have that care free life style. Just a thought....
