Salmonids

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 Central Coast 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.
