Chum salmon
Chum Salmon (Oncorhynchus keta)
Chum Salmon (pronunciation: /ʧʌm ˈsæmən/), also known as Dog Salmon or Keta Salmon, is a species of anadromous fish in the Salmonidae family. It is native to the Pacific and Arctic oceans and is one of the most widely distributed and abundant salmon species.
Etymology
The term "Chum" is believed to have originated from the Chinook Jargon, a trade language used by various indigenous peoples of the Pacific Northwest. The word "Keta" comes from the Evenki language of Eastern Siberia and translates to "fish".
Description
Chum Salmon are known for their large size, with adults typically reaching lengths of 60-90 cm and weights of 4.5-6.5 kg. They are characterized by their silvery-blue coloration and distinctively marked sides, which become more pronounced during the spawning season.
Life Cycle
Chum Salmon have a complex life cycle that includes freshwater and marine phases. They hatch in freshwater streams and rivers, where they spend the early part of their lives. They then migrate to the ocean, where they grow and mature before returning to their natal streams to spawn and die.
