| Comments | "Flathead catfish were probably introduced into the Snake River in 1943 as a misidentified shipment of blue catfish; other species of catfishes were more than likely introduced at the same time, including the tadpoles madtom; both species were in the lower Snake and Columbia Rivers by the mid 1970s." |
