This was a very experienced boar. He was very still, just moving his head around to focus in the water, then he’d pounce. Bears down have thumbs so they have to maneuver the wriggling fish by stepping onto it then using their claws/paws to lift it to their mouths.
The sockeye turn BIRGHT RED (these photos are not enhanced) when spawning.
This bear never took any chance of loosing his fish in the water and always carried it to shore and hid in the trees to eat it.
