The way most updates work is that you need to do them either where you clearly know the stock (terminal area/bay-river) or invest in genetics or scale reading to separate mixed stocks. With pink there used to be Fraser Panel genetics work that would at least give a heads-up as to what US (read Puget Sound) pinks were doing on the approach routes. It would money and commitment to rapid turn around to get mixed-stock updates for pinks.

Pinks are probably not worth the effort in WDFW's mind. Heck, since they don't many (if any) updates anymore maybe noe of it is worth the effort.
