Abstract During 1963 and 1964 collections were made in tributaries of
the lower Columbia River and literature was reviewed to compile a
list of fishes from that area.
Based on available sources and collections in this study, a
total of 28 families and 77 species are known from the lower Columbia
River. Most of the fishes are marine or have marine affinities.
Freshwater fishes include eight families and 29 species, but only
three families and eight species are primary.
In the Columbia River the peripheral family Cottidae reaches
great development in the absence of a more extensive primary fauna.
Seven of the 12 species of Cottus known from the basin occur in the
lower tributaries and were found to be the most widespread species
there. LocaI distribution of 25 selected species is discussed, and used
to gain an understanding of the relationship of the fauna of the Columbia
River with the fauna of the Puget Sound drainage and coastal
streams of Oregon and Washington. These 25 selected species included
17 species which are recorded from the lower Columbia River, and eight other species which are possibly present there.
A number of species occur throughout the Columbia River basin
and may have interchanged with other drainages at several points.
The absence of several species from the Puget Sound drainage was
associated with their absence from tributaries of the lower Columbia
River. Because these species were absent from the lower tributaries,
they were apparently unable to take advantage of the dispersal route
north of the lower Columbia River. Several species had unexplainable
distributions.
