It's not every day you see someone catch a brown trout by hand, that's for sure! Pretty impressive.
Before you start worrying about the fish handling (we all know trout have sensitive organs), know that these fish were trapped in one of two pools, both of which were not going to be pools they could survive in after the waters freeze (far too shallow!). These guys were trying to move them from the worse of the two pools to the better of the two, since there was no outflow for the fish to relocate via, either. So, it might just be that this chance is their last one! Hopefully some of the fish make it.
