Molecular Ecology 19(12):2562-2573. Coho salmon have a relatively complex life history that includes spawning and juvenile rearing in rivers followed by migrating to saltwater to feed, grow, and mature before returning to freshwater to spawn.

Currently there is one Endangered population segment of coho salmon, three Threatened population units of... Migration Behavior. Learn more about protected coho salmon. Anderson, J.H., P.M. Kiffney, G.R. Some evolutionarily significant units (ESUs) of coho salmon are listed as endangered or threatened under the Endangered Species Act. U.S. wild-caught coho salmon is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Coho salmon Natural History. Finding the depth where the silvers are schooled is another important element for success. Most Coho Salmon migrate only a short distance in the fall to spawn.

The Interior Fraser River population is genetically distinct from coho salmon that live in the lower Fraser River watershed. These runs generally extended from March through October, though steelhead runs extended through the winter. After spawning, all Pacific salmon and most Atlantic salmon die, and the salmon life cycle starts over again. As a population, Interior Fraser River coho salmon are descended from now-extinct populations of coho that survived the ice age by migrating to the upper Columbia River. Coho salmon are typically thought to favor small tributaries for spawning and juvenile rearing, however, substantial coho spawning and rearing has been observed in the mainstem Cedar River. 2008. ... Young coho typically rear for approximately 1 year in the Cedar system prior to migrating … Life history traits examined for naturally spawning coho salmon populations included smolt size and outmigration timing, age and size at spawning, river entry timing, spawn timing, fecundity, and ocean migration patterns based on marine code-wire-tag (CWT) recoveries.
