Coho salmon are also known as silver salmon (or "silvers") and is often sold as medium red salmon. [2] The scientific species name is based on the Russian common name kizhuch (кижуч).
The 1967 Coho Salmon Fishing Disaster [a] refers to a squall over Lake Michigan, off the coast of Michigan in the United States, which occurred on September 23, 1967. Hundreds of small fishing boats were on the lake to take advantage of a coho salmon run. More than 150 boats capsized, seven people died, and 46 people were injured.
A 2008 meta-analysis of available data shows that salmon farming reduces the survival of associated wild salmon populations. This relationship has been shown to hold for Atlantic, steelhead, pink, chum, and coho salmon. The decrease in survival or abundance often exceeds 50%. [66]
Coho salmon numbers have exploded in the Upper Willamette Basin to the delight of anglers and confusion of biologists. Coho salmon numbers smash records as 40K return to Upper Willamette Basin ...
Coho salmon mature after only one year in the sea, so two separate broodstocks (spawners) are needed, alternating each year. [dubious – discuss] Broodfish are selected from the salmon in the seasites and transferred to freshwater tanks for maturation and spawning. [14] Worldwide, in 2007, 115,376 tonnes of farmed Coho salmon were harvested ...
Parr – When a fry has grown to roughly the size of a human finger, it develops protective scales and sufficiently strong fins, and is thus colloquially known as a fingerling. Fingerlings will start moving to a more carnivorous diet and quickly gain body mass, and at the end of the summer they develop into juvenile salmon called parr.
The kokanee salmon (Oncorhynchus nerka), also known as the kokanee trout, little redfish, silver trout, kikanning, Kennerly's salmon, Kennerly's trout, or Walla, [2] is the non-anadromous form of the sockeye salmon (meaning that they do not migrate to the sea, instead living out their entire lives in freshwater). There is some debate as to ...
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).
