The Chinook salmon / ... The Klamath tribe had a similar legend that has illustrated the importance of not messing up the Chinook salmon migration. [57]
A grizzly bear ambushing a jumping salmon during an annual salmon run. A salmon run is an annual fish migration event where many salmonid species, which are typically hatched in fresh water and live most of their adult life downstream in the ocean, swim back against the stream to the upper reaches of rivers to spawn on the gravel beds of small creeks.
The lower Klamath River experienced a mass die-off of at least 34,000 adult Chinook salmon in September 2002, which was attributed to atypically low flows that delayed salmon migration and high water temperatures that allowed massive spread of ich and columnaris among the waiting fish. [146]
With low juvenile fish passage counts at Fall Creek Dam in recent years, as few as 10,000 salmon have headed to sea. Army Corps' Fall Creek Dam drawdown helps 50,000 salmon migrate to open ocean ...
Many species of salmon are anadromous and can migrate long distances up rivers to spawn Allowing fish and other migratory animals to travel the rivers can help maintain healthy fish populations. Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ...
The fishing industry depends on fall-run Chinook, which migrate upstream to spawn from July through December. Other salmon runs have declined to a point that they are at risk of extinction.
As salmon do not eat during their spawning migration, Yukon River salmon must have great reserves of fat and energy to fuel their thousands-mile-long journey. The Chinook, which arrive at the mouth of the Yukon River in early June, have the longest journey – as many as 2,000 miles against the current, with an estimated 35–50% bound for Canada.
[6] [8] In 2013, a genetics study of Napa River chinook salmon revealed that two adults migrated from the Klamath River and successfully spawned in the Napa River, since four juvenile chinook collected from the Napa River in 2010 were proved to be siblings from the close similarity of their DNA and that the latter was characteristic of Klamath ...
