List of freshwater fishes of Washington

The following list of known freshwater fish species, subspecies, and hybrids occurring in Washington state is taken from Wydoski and Whitney(2003). Some scientific names have been updated or corrected. Trout nomenclature follows Behnke et al.(2002). Asterisks denote introduced fishes. The list includes several anadromous species, and two normally marine species (starry flounder and shiner perch) that are occasionally found in freshwater. Only one species (Olympic mudminnow) is a Washington endemic, however three others (Nooksack dace, Salish sucker, and margined sculpin) have very limited distributions outside the state. Sixty-seven fish species, subspecies, or hybrids are listed, 37 native, and 30 introduced.
