If i don't intend to keep it i don't take it out of the water... Pics like that piss me off. I fish the washougal and have for 25 years, there used to be a ton of fish like that, now not so much.
I have caught 20 pound steelhead and they are awesome but i don't need to show it off to the world to feel good about myself. If that is what fishing is to you maybe you need to rethink the reason you fish.
And the reason they have the rule about removing native fish from the water is to reduce the stress on them because the more they are handled and the longer they are out of the water the less chance they have for survival.
