WDF tried in season management of the recreational salmon fishery in the late 70s, in response to Boldt. It was a complete failure for a number of reasons. Some of the reasons were:

Change on weekly basis (when updates were done) would mean that all anglers would need to be notified and there would be no "hard copy" available. How do you ensure notification for all? Commercials are easy as there were relatively few of them.

The updates would have to calculate allocations each time. A crash for a week or two in Green River Chinook could close the Straits and Ocean.

Sampling would need to extensive (all marine areas, all fw areas) and have a very short turn-around. Again, sampling the nets is a lot easier as there are fewer and you know the buyers.

If you want a marine mixed stock fishery of any modest or larger size you will need to accept fishing on forecasts.
