I have asked some of the game wardens about the hybrids that were stocked in Sardis, I think they were also stocked at Enid or maybe even all of the Big 4 Reservoirs up here, they said that first off hybrids are generally sterile and since they weren't reproducing they all either got caught, floated down the spillway or died of natural causes eventually. As for not restocking them, I think they say that they are expensive(having to restock them on a yearly basis), harder to get them to survive(especially in the Summer, and that there is a lack of angler interest in catching them. I have to personally disagree with that, I for one would love the chance to catch some hybrid bass while I am in school up here at Ole Miss. I think there would be plenty of others that would like to target them as well, they can put up quite a fight and are very sporting. They should survive quite well in the reservoirs up here (at least Enid, Grenada and Sardis) because there is enough deep water for them to cool off in the hotter months. If they can thrive at Ross Barnett, the sea runs, then hybrids ought to be able to make it up here.
