Summary

Salmon, trout and steelhead are all members of the taxonomic family Salmonidae or Salmonids (plural noun). Many species of salmonids are strictly anadromous, however, there are species which do not express an anadromous life history. Furthermore, sibling rainbow trout (Onchorhynchus mykiss) which come from the same parents can exhibit different life histories where one shows anadromy and the other remains in the stream as a resident trout.

The California Central Coast (CCC) Region supports two species of salmonids: rainbow trout and Coho salmon. While they are known to reproduce in similar habitats, only a limited number of coastal watersheds in the region still support both species.

Rainbow Trout & Steelhead

Central California Coast Steelhead DPS
South-Central California Coast Steelhead DPS
Southern California Steelhead DPS

The Steelhead found in the CCC region are divided into three Distinct Population Segments (DPS): Central California Coast Steelhead[1] (STCCC), South-Central California Coast steelhead [2] (STSCC), and Southern California Coast Steelhead [3](STSCA). South-Central steelhead are the most prominent DPS here, with their biogeographical range spanning from Santa Cruz to a few coastal streams just south of San Luis Obispo (i.e. Pismo and Arroyo Grande Creek). Central California Coast steelhead inhabit streams in the Santa Cruz mountains and regions further north into Marina and Sonoma County. Because their range overlaps with the Coho salmon populations in the region, there are seven streams in Santa Cruz County where both species are regularly observed to spawn in during their respective migration periods.


Protection Status of Steelhead Distinct Population Segments (DPS)
DPS CESA Status ESA Status
Central California Coast Steelhead (STCCC) [1] NONE Threatened [4]
South-Central California Coast Steelhead (STSCC) [2] NONE Threatened [4]
Southern California Coast Steelhead (STSCA) [3] NONE Endangered [4]

Coho Salmon

Extant populations of Coho salmon in the CCC region are found in coastal streams of San Mateo and Santa Cruz counties.[5] 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.[4] At this time they were also listed as endangered in the California Endangered Species Act in a join effort to preserve these populations from further decline.[6] The COCCC DPS is the only extant population segment of Coho salmon in the CCC Region.[4]
