No doubt, you see all too often folks with very poor handling skills weather it's sturgeon, steelhead, stillwater trout or salmon. Seems a lot of folks are putting themselves, (I'm not saying you are, hrenya) or the need for the hero shot ahead of the well being of the fish. And have seen ridiculous fish handling skills without them even taking a picture also.
If you keep the fishes well being and respect ahead of yourself, rarely will problems occur. Seen reputable guides keep sturgeon in 2 inches of water for 15 minutes taking dozens of pictures and have seen guys on lakes keep the fish in the boat for far too long, sometimes literally minutes, before release more often then I'd like...it is ultra frustrating to have to witness it and if you do witness someone mishandling fish, politely go over to them, respectfully voice your concern and hope they do better next time, that is about all we can do. But before everything the respect for the fish must come first above anything else including the coveted hero shot.
As some have displayed here, it is possible to get that nice shot and have the utmost respect for the fish at the same time how ever it can sometimes be a fine line as some's standards for common sense etiquette can differ greatly. Just be mindful of the fish when handling, they can't breathe out of water and doesn't take long for the damage to be irreversible.
