"For whatever reasons, during the past few years, the population of white perch in Lake Norman has mushroomed. Huge numbers of perch are propagating. In a few short years, the previously significant population of white bass in the lake has been decimated, probably by white perch. White perch may have simply eaten the white bass fry and eggs and competed directly with them for the limited forage. Perch are excellent table fare and anglers are encouraged to catch and keep as many as possible. However, angling alone cannot keep the population of white perch in check. Currently, white perch offer an excellent opportunity for those anglers seeking large numbers of fish for table fare. The question now is whether the current populations can be controlled to maintain a quality new fishery. If white perch overpopulate Lake Norman in the future, they will inevitably become stunted."
