From TCW economics 2008 final report "Economic Analysis of the non-treaty Commercial and Recreational Fisheries in Washington State" I found the following 2006 estimates.

For steelhead some 113,000 anglers fished 1.1 million days

For salmon 294,000 anglers (both fresh and salt and I expect that included some cross over) fished 2.5 million days.

All other marine fish 44,000 anglers fished 187,000 days

To put those values in context there were 337,000 trout anglers fishing 3.6 million days

Total value of the recreational fishery was $462 million (with 9 million angler days). I would expect the number of anglers fishing salmon have increased since 2006; if for no other reason than larger pink runs, more mark selective opportunities in Puget Sound and increased Columbia river runs. As the value of the angler day has increased substantially; the latest WDFW report that I saw (Columbia endorsement report) used a value of $82/day. That would put the value of 9 million angler days at approximately $738 million.
