Chum salmon

Chum Salmon (Oncorhynchus keta), also known as dog salmon or keta salmon, is a species of anadromous fish in the salmon family. It is a Pacific salmon, and is distributed in the North Pacific Ocean, including the Arctic Ocean.

Description

Chum salmon are the largest of the Pacific salmon species. They can grow up to 1 meter in length and weigh up to 16 kilograms. The body of the chum salmon is deeper than most salmonid species. In common with other species found in the Pacific, chum salmon are semelparous, dying after they spawn.

Life Cycle

Chum salmon have a complex life cycle that includes freshwater and marine phases. They hatch in freshwater streams and rivers, then migrate to the ocean as juveniles. They spend several years at sea, where they grow and mature before returning to their natal streams to spawn and die.

Distribution and Habitat

Chum salmon are widely distributed in the North Pacific, from the west coast of the United States and Canada, across to Russia and Japan. They are also found in the Arctic Ocean. They prefer cooler waters and are often found in coastal waters and estuaries.

Conservation Status

Chum salmon populations are currently stable, but they face threats from habitat loss, pollution, and overfishing. Conservation efforts are focused on protecting their spawning habitats and managing fishing to ensure sustainable populations.

Economic Importance

Chum salmon are commercially important and are harvested for their meat and eggs. They are also popular with recreational anglers.
