I think I can help you a bit. My freind of many years father, owns many ponds, heck we all do round here. One of his ponds is a crawfish pond where he raises them. He told us years back that his daddy used to catch numbers of drum with crawfish for bait. So the first thing that came to his mind when he built it was drum. Now I dont know how many, but I know they have some nice ones in there. I also know these were caught at ross barnett reservoir and transported. They have been in there for at least 7 years since i was like 15. Never had any problems that I can see. But then again he never lets anyone fish it, go figure.. just thought i'd add my 2 cents.
