During my management years the (in my mind) best management of Pacific Salmon was the Fraser sockeye (for sure) and Pink fisheries. One of the keys was that at the weekly management meetings the staff went over current and historic data back to and before 1900 so that the decision makers had not only all the information but all the sideboards that might affect decisions.

As I remember, most of our (WDF) decisions were made based on an evaluation of the current numbers almost entirely.
