Stop making something out of nothing. Most guide are are Stewards of the river - sure there are some that are questionable - people are not perfect.
I really don't see anything there that is cause for alarm. Catch the fish, quick hero shot and into the drink it goes.
Next we'll start saying we can't fish for Steelhead out of a boat because you net them and then they thrash around while you try get the hook out.
Or we can't fish for them from shore because too many people are bringing them to shore to get the hook out. Sand might get into their gills or they are giving themselves a concussion as the whack their heads on the rocks.
Someone saw dead Pinks in a deep pool during their spawn season. Yes - the salmon die after they do their business. Yes - some fish die after they are stressed by poor handling.
You will never educate everyone and even if you do, people get greedy and anxious and stupid and ...
We can only do our best to try inform someone of the right way to handle fish if you see they are having difficulty or obviously don't know what they are doing.
Even despite our best efforts, sometimes a fish is going to die.
It's okay that we're not perfect as long as we try do what's right.
I'm certainly not going to try thrash a local guiding business for a picture that some might think isn't perfect. Unless you were there on the boat or witnessed the activity first hand, how can you say something was done wrong? Nice fish and nice hero shots.
