1-2 minutes of being hoisted into the air could potentially be detrimental to a salmonid's well-being, because these fish aren't adapted to take in raw air. There is a reason they have gills. I'm sure that if you have been at a lake or tiny stream in the heat of summer, you may have seen trout poking their heads out of the water to gulp down air. However, this is not normal behavior and usually happens when water temperatures are at uncomfortably high levels. For the most part, fish don't surface for air, they open their mouths to breathe.
