I'm almost 2 years into establishing a blue catfishery. I don't have much advice for forage fish selection, but mine seem to be thriving on young crappie, carp and channel cats. On top of that I go thru as much feed as I feel comfortable with financially. Another thing that has come along lately is I've begun throwing in cleanings from a commercial trout farm down the road. I'm hoping the blues take to eating that. I also have an ability to seine to cull out my over population of channel cats. Keep me informed on how your Blue Catfishery goes as it doesn't seem like many people have tried it.
