I have been working (volunteer) at a local native hatchery on the King run this year. The return to the hatchery was only a bit above what they needed to run full bore........I was told the mark rate here is 50%. I would say the majority of the fish were unmarked, so it appears some unmarked fish may be necessary to continue business as usual.........sportsmen got to fish for these same fish from the ocean all the way into the Seattle area.
