Keep a sharp eye on your largemouth population. Keep that strong and the bullheads, green sunfish and crappie populations should be ok. Still remove any you catch though. I�d be more concerned about the carp than any of the others, primarily because they can be difficult to catch and can obviously outgrow the prey size of your largemouth. What size largemouth were stocked? I might consider stocking a few larger bass to keep those unwanted species from getting ahead.
