FishingDoc -
Remember that the ocean fisheries are mixed stock areas. The differences between the options are how much of the allowable impacts are being allocated to ocean fisheries versus a more terminal fishery.

In theory it would be possible to catch all the allowable impacts on say an upper Columbia/Sanke river chinook stock in the ocean fishery. Therefore there would not be any fishing that might catch those stocks anywhere else (say mouth of Columbia or up river). To put it simply option 3 would have 1/2 the chinook imapcts of option 1 thus "reserving" those impacts for other "inside" fisheries.

Whether that is a good deal or not really depends on where you fish - which is what the North of Falcon and PFMC processes are all about.
