MrH, I lost most if not all of these fish in a fish kill.
The following link will document pure immature CNBG stocked following the fish kill and caught February 2009.
http://www.pondboss.com/forums/ubbthreads.php?ubb=showflat&Number=207020&page=1I will document further growth this fall.
I feed about 6lbs/acre Purina Aquamax 500/600 except coldest and hottest months - twice a day.
Currently about 150lbs/month at a cost of ~ $100/month
BG are raised on fish food and will go on feed as soon as consistant schedule established
No catfish - they are a problem if population in not controlled.Good luck on your program.
