RE: I just stocked my Pond with Bass.
The channel cats will probably nab a few, but most will survive them. As a general rule, you can stock bass in a catfish pond, but you can't do the reverse because the bass will eat all the catfish. You can also stock them at the same time, but the catfish need to be as long or longer than the bass.
If there is a bigger bass in there, he will probably make a bigger dent than the catfish. Since the bass you are stocking aren't very big, be prepared for them to suffer a bit of predation. Even if there were no other fish, other predators, such as birds will still claim some. The key is to stock enough that the predators can't eat them all. Good cover helps, as does having plenty of other forage for the predators.
At 2", expect a pretty high mortality rate.
