Oregon chub

The Oregon chub (Oregonichthys crameri) is a species of ray-finned fish in the family Cyprinidae.

From 1993 to 2015 it was a federally listed threatened species.Their scales are relatively large, with less than 40 on their lateral line.

This chub is native to the drainage of the Willamette River in Oregon.

Dams and channels were constructed and non-native species of fish were introduced to the area.

Fish and Wildlife Service said that the small, silver-speckled minnow would become the first fish to be taken off the endangered species list when its numbers returned from fewer than 1,000 individuals to an estimated 160,000.
