Recent events have interesting parallels.

The pilots of the Asiana plane goiung to SFO flew the plane by the (pre-season) models-all the various automatic controls. Even after taking them off they apparently ignored the Real-World data. They were too low and too slow (run not materializing as expected). They took action at the last moment (closed the in-river sport fishery) and still broke off the tail (missed escapement).

In fish management, as in flying a plane, real world data and hands-on management seem to be needed. Unfortunately, this is expensive, time consuming, and may result in "aborting the landing"-closing a bunch of fisheries.

Or, keep flying on autopilot; it works most of the time.
