Willamette Valley Nonnative Fish

Willamette Valley is home to a variety of nonnative fish from around the world. People from around the world have introduced nonnative fish which threaten indigenous fish populations who compete for the same food, and threaten the overall ecology of the willamette basin. Many of these fish have become over populated and widely fished in Willamette Valley.
