While still feeding in tidal waters, the chinook has a dark back, with a greenish blue sheen. As they approach fresh water to spawn, the body colour darkens and a reddish hue around the fins and belly develops. The teeth of adult spawning males become enlarged and the snout develops into a hook.

Although ocean-going sockeye are silver in colour, with small black speckles along the body, the recollection many people have of this fish is that of the sockeye returning to freshwater to spawn.
