Bought a pound of fat head minnows and went fishing for crappie that I haven’t seen in a while. Didn’t catch any crappie but started catching LMB 8-9” and removed them . Several were 2-4# removed them also. Think I’m overloaded with LMB causing the decline of BCP. The larger LMB are fat but the 8” are thin for the most part. Any ideas how many LMB to remove to change the dynamics of a six acre pond?
