Intelligent management would balance the hatchery production with the wild runs in areas where one can fished mixed stock. In the first couple of iterations of the Puget Sound Salmon Management Plan all terminal areas were managed for either hatchery or wild. That meant surpluses at some hatcheries and blowing away the wild stocks in others. It works in terminal areas but in the big marine fisheries the controlling stocks are the weakest ones. Massive mixed stock fisheries are a thing of the past unless we, as a society, decide we don't want meaningful populations of wild fish.
