csullivan,
I'm not familiar with "feeder bass". I have Florida bass in one pond, native bass (northern) in another, and a cross called F1 in a third pond. The F1 is possibly what your fish supplier is talking about. I would ask him/her for specifics.
I don't think you need 100 pounds of feeder base. You need to do two things as quickly as possible.
1) remove every one of those blue catfish, and any other kind of catfish in that pond. They compete directly with LMB, and blues even outcompete LMB.
2) remove every LMB 12 inches and under...as soon as you can and as many before next spring as possible. There is only so much forage to go around, and from your description, you do not need more bass, you need less small bass and no catfish.
If you really want to get into this, then consider a couple of more options (both of these are somewhat controversial but I have done both myself with great results).
1) stock Tilapia next spring at a rate of 5 to 15 pounds per acre...on the high side if you also want algae control. Todd Overton carries them but get your order in early.
2) stock gizzard shad. They provide great forage and are suitable for stocking with mature bass, Gizzard shad can grow fairly large and make a very tasty meal for the large LMB.
