An environmental summary created by the ENVS 560/L Watershed Systems class at CSUMB.

Anadromy

Fish that are anadromous migrate into rivers an streams to spawn.

Salmonids

There are three species of salmonids found in the CCC Region: Steelhead, 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.

Steelhead

Coho Salmon

Extant populations of Coho salmon are found in coastal streams of San Mateo and Santa Cruz counties. Originally listed as threatened on the ESA in 1996, the Central California Coast Coho Salmon (COCCC) DPS protection status was reclassified to endangered in 2005. The Central California Coast Coho Salmon ^[2] (COCCC) DPS is the only extant population segment of Coho salmon in the Central California Coast Region, Coho Salmon in the Central Coast.

Central California Coast Coho Salmon DPS

Conservation and management objectives for the COCCC DPS are listed under the Recovery Plan for the Evolutionarily Significant Unit of Central California Coast Coho Salmon of 2012.^[2]

Describe significance of these populations, their threats here in the region, and reference the recovery plan.

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

Pacific Lamprey

Armored Threespine Stickleback

Striped Bass
