George the reason you don't see small CNBG in your pond is with its fertility the CNBG only stay that small about 2 weeks. ;\)

Crappie are different. See Crappie Pond http://www.pondboss.com/ubb/ultimatebb.php?ubb=get_topic;f=5;t=000461

In that series of threads it is discussed in great detail. Not only do they have unpredictable population swings they exhibit cyclical growth. In terms of them being a forage base that means in some years there will be little for LMB or HSB to eat absent feeding.

David I would suggest if you try a HSB and crappie pond you will have to feed and track the crappie growth cycle with the idea on some years you will have to add forage (FH , tilapia, minnows , TShad). In fact a standing crop of TShad would be great for both crappie and HSB. I would like to see what happens and if I can help in the planning let me know. Like Rad says - If you are not living on the edge you are taking up to much room. \:D
