King salmon are native to the North Pacific Ocean and the river systems of western North America. They are quick travelers, constantly swimming long distances to new bodies of water. For example, you can find them from California to Alaska. Other than North America, king salmon also swim through Asian rivers, including Japan and Siberia. While they have been introduced to other parts of the world, like New Zealand, they aren’t native.

Size and Appearance

King salmon are colorful and shiny fish. Some of these fish have blue-green, red, or purple coloration on the back and top of the head. They also have black spots and markings on their tail. King salmon are unique because they have black and silvery marks also on the upper half of their bodies. Interestingly, the meat inside their bodies ranges in color depending on what they eat. Some king salmon are pink, while others are white.

Although these fish are very beautiful and shiny, what’s most impressive about them is their large size. King salmon are about 24 to 36 inches long. Not only are they long, but they can also weigh up to 126 pounds. However, the average weight for a wild-caught king salmon is 10 to 50 pounds.

Diet

King salmon are carnivorous fish, but their diet depends on where they live. Some king salmon spend most of their lives in the ocean, while others prefer freshwater rivers. King salmon are born in freshwater but migrate to the ocean as they mature. Adult king salmon consume shrimp, small squids, pilchards, herring, and other small fish. Young king salmon consume plankton, insect larvae, insects, and crabs.

Predators

King salmon have many predators. The most common predators that also live in water include seals, sea lions, whales, and sharks. However, some large mammals that live outside of water, like grizzly bears, also hunt for king salmon when available. This is more common in North American rivers. Young king salmon is a lot smaller. The biggest predator that hunts for juvenile king salmon is bass.

Fun fact, the largest king salmon ever caught in Alaska is also the largest king salmon caught in the world! This large and impressive fish was caught in a fish trap near Petersburg, Alaska, in 1949, weighing a whopping 126 pounds! While this is the largest king salmon ever caught, other impressive records exist. For example, California Department of Fish and Game biologists found a Chinook carcass in Battle Creek. The carcass was 51 inches long and weighed 88 pounds dead, which means it could have easily been 100 pounds alive!

The current IGFA all-tackle record, Chinook, is another impressive catch. In the Kenai River in May 1985, Les Anderson caught this massive 97 pounds, 4-ounce king salmon. It wasn’t weighed for hours after it was caught, which could mean this catch was over 100 pounds.
