Dale says"I think I will just have to stock LMB right away instead of waiting for my forage fish to multiply then just try and harvest the bullheads."
I agree. If it were my pond and since you already have bullheads I would try to find some fish farm with larger bass of 5"-8". Get them stocked soon before the bullheads spawn. This way the bass will help a lot to control this year's new crop of bullheads. Then in the next few years, work to remove the current resident population of several sizes of bullheads. Bullheads enter baited fish traps pretty well. Build yourself one or two larger fish traps. So a conscious effort to trap and fish for bullheads will help a lot to thin the BH. If you don't have a bass spawn this spring, then also stock some fingerling bass now or this fall. This provides several year class of bass to prey on various sizes of BH. With pellet feeding you can have a pretty good general fishing and fish food pond with bass, BH and a panfish such as RES or HBG. RES and or HBG (4"-6" or 3"-5") could be stocked anytime this year.
One style of larger fish trap. Various sizes can be made. Other styles are also good to use.
