If you could get a free electrofishing survey that would be spectacular. Especially since your pond would be one of the few ponds that have only small numbers of BCP. Maybe you could figure out what ratio of the other fish and predators you have that allow for the control of BCP numbers and others could learn from that.

You also would have to wonder about tilapia survival when CC and LMB are in place. Probably depends on stocking size of the 40 pounds of tilapia and the gape size of your LMB.
