Ok with a little help I finally was able to track down the info I was after. This is not an IDFG [#ff0000]edited[/#ff0000] crappy response either.
"That is a very nice fish. I hope it was a warm day in the 40's. If you take a cold blooded fish that is in 34-38 degree water and lay it on snow, the skin will rapidly assume the temperature of the snow as will the eye on the side of the fish next to the snow. The result is what we call frostbite on humans but since they warm blooded animals it happens fairly slowly. On fish, going from 34 to 30 degrees happens very quickly.
When it is colder, say below 25, the fish opens it's mouth trying to take "a breath' and the cold air hits it's gills causing them to freeze which causes hemorrhaging once the fish is put back in the water and released. In both situations above, mortality is delayed for hours or days. Some fish can live a long time with only one eye.
I am not against fish porn and have taken my fair share of pictures in the past, but if it is below 32 degrees the best choice is to not remove the fish from the water and never lay the fish on the bank in any weather unless you are going to bonk them and eat them, then no harm, no foul.
