An adult salmon is now in the ocean free from its spawning ground. Adult salmon spend 1 to 4 years in the ocean swimming and feeding throughout the Gulf of Alaska and the Bering Sea. They grow up to there adult size and develop unique adult markings that are different for all five species of Alaska salmon. The upriver salmon run is one of nature’s great migrations. Each year mature salmon make the long journey back to their natal river to reproduce, just once. For the five species of Pacific salmon (Chinook, chum, coho, pink, and sockeye), this arduous journey is a race against the clock that ends in a fleeting romance and ultimately death.
In the final stage of the salmon’s life cycle, the adults re-enter their home river and swim back to the stream or lakeshore in which they grew as fry. Salmon from inland rivers may travel many hundreds or thousands of kilometres, swimming from 30 to 50 km a day against the current. When the salmon reach the ocean they are considered to be adult salmon. They will stay in the ocean from six months to five years. They will feed mostly on shrimp, squid, and small fish. Adult salmon may travel thousands of miles from the stream they were born in. When they are fully mature they return to their home stream to spawn.
Many of us have grown up watching nature shows that present dramatic footage of large salmon swimming and leaping heroically upstream to spawn. For many, that image is a last act of the salmon -- and not just because a bear got to the leaping fish. A few species can spawn more than once in a Author: Chris Marlowe. In fall and winter (September-January), adult salmon can be seen returning to the river to spawn. There are several good salmon viewing spots along the Duwamish River. Codiga Park, 50th Place South, Tukwila, WA 98178. See Chinook, pink, Coho, chum, and steelhead salmon migrate up the river.
Spawning. Salmon reach sexual maturity at 2 to 8 years old. Different species mature at different rates. See below for information on the spawning of each of the five salmon species on Togiak Refuge. Adult Salmon The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning.Author: Ningthoujam Sandhyarani.
