thanks for that info ewest--will read those threads tonight. i wouldn't mind following along your type guidelines on fertilization if it works on my pond---certainly i'm sure all ponds are different. theo--i was teasing greg about the gambusia --i would think even a 3lb fish with a belly full of 1 inch fish would still be full and growing--i'm pretty big myself and several plates of small all you can eat catfish does the job on me. ha.
Off topic: i would really like to thank the moderators of this site and the people who have responded to my questions---i have read and learned much over the past 6 months. i am reminded of an old friend who has passed on now that i used to fish with--he had a degree in ichthyology (also raised catfish)and he had 8 ponds on his property--- there wasn't much he couldn't tell you about fish and ponds. i regret i didn't ask and learn more from him while he was alive and also regret he didn't have the opportunity to enjoy and contribute to this web site as he could have been much help to many people and i'm sure he would have loved debating some of the topics here with you folks. this is a truly great site with much to learn from. thank you all.
