Maybe I could take out all bass i catch and try to make the Blue cats the primary predator. Eventually I'd think the blues would start using the bass as forage.
If I keep the bass numbers down and forage high for long enough to get some big Blues then they would take care of the bass population a little by themself.
Here is a good article about blue catfish in the James River in Virginia.
Blue Catfish Now James River's Biggest Predator I don't know much about blue catfish, but I would think you could grow some pretty big ones in your pond. I don't think you would have to remove the bass. My guess is that in a few years the growth of the blue catfish would be at the expense of all the other fish in the pond. Depending on your desires, that could be real good.
Until the big catfish have eaten themselves out of forage, you'd sure have some pretty impressive bragging rights. Then, you could start all over again with whatever fish you wanted, and it would have been a lot more fun than putting rotenone in the pond.
If I had an extra pond or two, I would consider it as a fun adventure.
