Anadromy
Fish that are anadromous migrate into rivers an streams to spawn.
Salmonids
There are three species of salmonids found in the CCC Region: Rainbow trout, Coho Salmon, and Chinook Salmon. Declines in their populations from human development, fishing pressure, and climate change has necessitated state and federal recovery plans to ensure their conservation.[1] Chinook salmon are encountered by commercial and recreational ocean fisherpeople during periods of a given year, however, there are no known naturally reproducing populations of Chinook salmon in CCC region watersheds.
Coho Salmon
Coho salmon, commonly referred to as Silver salmon, are among the most resilient of the Pacific salmon species and are observed to spawn (reproduce) in streams as far south as Aptos Creek in Santa Cruz County, CA. In the Central Coast Region there are seven populations of Coho salmon, all of which are found in the northern section of the region.
Rainbow trout
Rainbow trout (Oncorhynchus mykiss) have the greatest life histories variability of any salmonid.[2]
Species Distributions in the CCCR [3]
Chinook Salmon
Chinook salmon (Onchorhynchus tshawyatscha) are commonly called king salmon, and support substantial commercial and recreational (sport) fishing industries on the California coast. Anthropocentric factors have lead to a decrease in their abundance and diversity throughout California, with most individuals in remaining populations being of hatchery origin.
While there are no spawning populations of Chinook salmon in the CCC region, the Monterey Bay Salmon and Trout Project (MBSTP) participates in an annual stocking program with the California Department of Fish and Wildlife (CDFW) to support local fishing industries. Juvenile salmon are transported (trucked) from Central Valley (Sacramento River Watershed) fish hatcheries to Monterey Bay and released as part of a state-wide hatchery supplementation strategy to abate fishing pressures on threatened and endangered stocks, and promote economic stability in local coastal communities.
Other Anadromous Species

Armored Threespine Stickleback
