This is the case of a lazy fishing grizzly. This bear is in a reasonably deep hole compared to the water just 30 meters (90 feet) up stream. The grizzlies up stream often wound salmon which die and drift down to this lower pool where this bear waits to scoop up the salmon without wasting any energy chasing the salmon. From the first picture is yesterdays post you can see the fish is not moving and it is just a matter of getting the salmon in the right position to eat or it could be considered playing with ones food. Either way the final photo seems to depict a satisfied grizzly.
