Both grizzly bears and black bears are known to eat Chinook salmon. These bears often fish for salmon during the spawning season, when the fish travel upstream to lay their eggs. Grizzly bears, in particular, are more commonly associated with salmon fishing due to their larger size and greater need for high-calorie foods. Black bears also partake in this food source, especially in areas where salmon runs occur.
Bears in general, need to put on enough body fat during Autumn, so as to survive the winter hibernation.
