Grizzly Bears Fighting Over Salmon 

That"s his momma...she is sending a clear message that she is not feeding them anymore...that they are on their own.

Bears want three things in particular from a salmon: the brains, the eggs, and the fat. If there is plenty of salmon, they will discard the rest. The rest, of course, is free for anyone to grab.

Lazy? He is hunting too. Fishing is mostly about luck

It momma...she is not providing for them anymore...they'll soon get the message.

They aren’t food for the bears

Eaten alive lol the fish is obviously dead. What the hell do you think fish are, one swipe or bite from the bear and the fish was instantly dead
