If you had a lake without LMB standard stocking rates would be between 100-250 RES/Acre. You don't want to be stocking 1000-2500 RES if they are only going to become LMB forage, though. I'd explore feasibility of blocking net FIRST, or cages, then determining stocking qty. As for where to source these fish, I don't know, but I bet Scott [Essup] can help you there and could probably arrange delivery - he's in the pond/fisheries management business and is pretty resourceful. If he can't help you need to probably consider driving for them - which is worth the trip for good fish, anytime IMO.
