In Oct. 2004 I stocked 300 6"to 8" channel cats in my pond in south Louisiana. I also put in 125 lmb, 500 coppernose, and 200 red ears. I have taken about 12 channels out to eat(are now about 15"s long. Should i buy more channels to get another age class or should i wait. We will be taking all channels we catch 15" or larger out of the pond we catch from now on. Thanks for the advise in advance.
