History of Chum salmon

In the north they range east in the arctic ocean to the mackenzie river in canada and west to the lena river in siberia. chum salmon are the most abundant commercially harvested salmon species in arctic, orthwestern, and Interior alaska, but are of relatively less importance in other areas of the state. There are known locally as “dog salmon” and are a traditional source of dried fish for winter use.

The chum salmon is a species of anadromous fish in the salmon family. it is a Pacific salmon, and may also be known as dog salmon or keta salmon, and is often marketed under the name silverbrite salmon. The name chum salmon comes from the chinook jargon term tzum, meaning “spotted” or “marked”, while keta in the scientific name comes from the Evenki language of eastern siberia via Russian.

Chum salmon also known as dog salmon, calico salmon or keta salmon, is one of the seven species of Pacific (“true”) salmon (genus Oncorhynchus). Of all the Pacific salmon, O. keta has the largest native range, inhabiting the Northern pacific ocean, Bering Sea, and further into the arctic ocean than its congenitors.

As anadromous (migrating between fresh and marine waters) fish, chum salmon spawn in fresh waterways, usually in the lowest parts of streams within 100 km from shore, in rivers from korea across Russia and alaska and as historically as far south as central california, although populations no longer spawn south of Northern oregon.

Distribution and habitat

Chum salmon fish photoChum salmon have the widest distribution of any of the Pacific salmon, and undergo the longest migrations within the genus Oncorhynchus, far up the yukon river and deep into the amur river basin in Asia. In lesser numbers they migrate thousands of kilometres up the mackenzie river. chum are found around the north pacific, in the waters of korea, Japan, and the Okhotsk and bering seas, british columbia in canada, and from alaska to california in the united states.

After hatching, the fry begin an immediate downstream migration and will remain in estuaries and near-shore areas for days or months before entering the ocean. Once adapted to marine waters, populations in the northwest pacific ocean will move into the bering sea and the Gulf of alaska. they will spawn in small side channels and other areas of large rivers where upwelling provides ideal conditions for egg survival. they will also spawn in small streams and intertidal zones.

Lifecycle of Chum salmon

Chum Salmon Temperament / Behavior

Chum salmon photoMigrate from a marine environment into the freshwater streams and rivers of their birth. they spawn only once and then die. Enters freshwater during advanced stage of sexual development and spawning occurs almost immediately. Spawning occurs at depths of ~3 meters, current speeds of ~20cm/sec. near the head waters over sand and pebbles at 4-11° C water temperature.

At spawning time the female excavates a hole of around 1 meter diameter and 50 cm depth before spawning can occur. A fish spawns 700-7,000 eggs in two to three egg releases. Eggs are ~300-3,500 per spawn. Egg size is ~6.7 mm, water temp. is 8-10°C at 60 days before hatching. larva size is around 16 mm. come springtime the juveniles go to the ocean and come back 3-4 years later to their exact birthplace.

Feeding for Chum salmon

Chum Salmon feed on pretty much the same things as other fish. They eat insects and marine invertebrates while in rivers. when they mature, their diet changes as they are larger and in the ocean. Here, they eat copepods, which are tiny crustaceans and small fish including herring, mollusks, squid and tunicates. Tunicates are sea worms.

However, other salmon species will eat many {more|more} insects as they spend more of their life in river habitats. chum Salmon are either in the river when they are born or when they spawn at which point they will also die soon after.
