Chum salmon

About Chum salmon

• It is a species of anadromous salmonid fish, which means they hatch in freshwater streams and rivers and then migrate out to the saltwater environment of the ocean to feed and grow.
• They do not reside in fresh water for an extended period.
• They are also known as dog salmon.
• Distribution
  • They are the most widely distributed of all the Pacific salmon.
  • They are found throughout the North Pacific Ocean and range from the Arctic coast of Canada and throughout the northern coastal regions of North America and Asia.
• Habitat
  • They spend their early life growing and feeding in freshwater streams, estuaries, and associated wetlands.
  • They spend the remainder of their life foraging in the ocean before returning to the streams and tributaries where they were born to spawn.

Q1) What is Salmonid?

Salmonids are carnivorous predators of the middle food chain, feeding on smaller fish, crustaceans, aquatic insects and larvae, tadpoles and sometimes fish eggs. They have a relatively primitive appearance among teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back.
