I have fished Neah Bay off and on the past 40 years, but regularly the past 8 years and the recent regs. always require release of wild coho. The regs. usually allow retention of 2 kings, then 2 hatchery coho (or you can retain 2 more hatchery coho if you don't retain kings).
Based on my experience, the drill is to catch and release 8-10 wild coho for every hatchery coho you find. So, why the heck isn't retention of wild coho allowed? There seems to be emormous abundance!
Also, despite careful handlling you will likely catch every 5th coho in the gill or somewhere causing a terminal wound, so this dumb policy often results in 4-5 dead wild coho to catch 2 hatchery coho.
In sum, what is justification for continued nonretention of wild coho? And, current policy probably results in more damage to wild coho than if retention was allowed.
