I know the GShad population can explode initially, but isn't it fair to assume that large lakes such as these will have decent numbers of mature LMB? Especially in the south where LMB approach double digits much sooner than up north, isn't it a matter of time before the LMB (or other predators) bounce back and keep the GShad in check?
We (unintentionally) have GShad in our LMB pond. The pond is only about 3.5 years old, which means we don't have an established fishery with lots of mature LMB. But so far the predators (largest bass) have kept them under control. The electrofishing survey produced good numbers of GShad, but nothing alarming. The largest bass also had the highest Wrs. I would predict the same thing in a larger lake with a moderate to high population of GShad.
