I ditto what RIc said. I think most folks understand carrying capacity is not an exact number, and realize it changes as population dynamics change. However, you hit on the more important point of competetion. It is all about your goals. If you want to maximize bass growth for trophy bass you should not stock, channel catfish, hybrid stripers, small mouth bass, etc. However if you don't mind giving up some bass growth to enjoy hybird bass action then stock them, just realize you are definently lowering the potential bass growth by lowering forage base.
