Greg, I can't be mad at your input; my experience is based only on my one pond that I've had for a whopping seven years; and I've certainly threw a wrench in the eco-system that was in existence prior to my arrival.

While my 6-7 acre fishery is very diverse, I've also had the benefit of having some large adult fish stockings. It does not seem like others have had this option. I think I'll start another thread on that topic.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
