Marty ... I'll have to disagree with you on several points, and add several that you forgot:
1) The glove ... a glove is probably alright IF it is non-absorbant. That means get whatever you have sopping wet before you ever touch a fish with it, and no cotton or wool. Personally, I don't use a glove ... never seen a reason to, I don't have any trouble most fish. The fish is always held over the water and if it squirms and gets free, it's in the water and no big deal.
2)The gill rakers ... don't touch period! Do not use a net that has large enough mesh to allow it to entangle in a gill.
Do not use bait divers!!! Spawners will gargle them and die, as will a number of the fresh fish!!!! Marty, the guide you defend uses these nearly exclusively! I discontinued 99% of my use of these during wild steelhead season years ago. Tactics must be changed in order to protect the fish.
3) Well said ... more technically, you're going to lose slime in the dry rocks and sand, causing infection.
4) If done properly, shouldn't be a problem. That means: have all cameras ready before EVER taking the fish out of the water; don't keep out of the water for 10 seconds MAX (find an old copy of STS for study reports on this one). Never bring the fish into the boat or hold above dry ground that the fish could fall onto if dropped. Again, always hold the fish over the water.
5) Huh??? Marty, the whole river is spawning ground! Did you know that lots of fish spawn in the Quillayute itself?? That's many miles from the C&R water on these systems! Ever had those little white glass boats float down over the water you're fishing in the lower end of the river?? There're counting redds. Instead, anglers need to recognize what is spawning water and what isn't. From top to bottom in a river system, you have both all the way through. If it's spawning grounds, don't fish it PERIOD, whether you're keeping a fish or letting it go, let the fish be on their beds!
6) Sounds good to me.
