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.
Lagunitas Creek is a 24-mile-long (39 km) [2] northward-flowing stream in Marin County, California. It is critically important to the largest spawning runs of endangered coho salmon (Oncorhynchus kisutch) in the Central California Coast Coho salmon Evolutionary Significant Unit (CCC ESU). [3]
Reclamation asked the California Department of Water Resources Fish Passage Improvement Program for potential improvements for redirecting salmon to the hatchery. The DWR suggested for the fish ladder to be extended to the stilling basin downstream of Nimbus Dam, with the dam becoming the barrier for the salmon.
In some recent sleuthing by salmon scientists, more than 3.4 California hatchery salmon of all runs were marked beginning last spring by coded wire tags to follow their whereabouts.
Biologists have begun collecting California's spring-run Chinook salmon to raise them in captivity in an effort to prevent extinction.
The Yurok Tribe said salmon will not be served at its annual festival because the Klamath River's forecasted fish run is one of the lowest on record. California Salmon Festival will be missing ...
In its natural state, it was the third-largest salmon- and steelhead-producing river system in California, with over a million fish spawning annually, after the Sacramento and Klamath rivers. The annual chinook salmon run was estimated at 100,000–800,000, coho at 50,000–100,000, and steelhead may have numbered as high as 100,000–150,000. [16]
