Chum can live 3 to 5 years and weigh 3 to 8 pounds (1.5 to 3.5 kg.) On average, they are about 2 1/2 feet long (75 cm.)
Their flesh, which can be white or a pale yellow, is mild and the firmest of all salmon; they also have a lower fat content than many other salmon.
Chum are considered less desirable because their flesh doesn’t have the colour that consumers associate with salmon.
Called “sake” in Japanese, just like the drink, but pronounced differently.
