A Guide to Freshwater Fishes of Oregon

Markle mentions 138 species and subspecies of freshwater fish, 50 nonnative and 88 native, in 25 families, but does not describe them all. Nonnative fish include all that have been seen alive in Oregon fresh water, whether or not there is evidence of self-sustaining populations. Among the families he describes are lampreys, sturgeons, catfish, pikes, smelts, salmon and trouts, freshwater cods, silversides, sticklebacks, seabasses, perches, and flounders. He includes an identification key to Oregon fish as a whole, and identification keys for each family, with color illustrations--mostly photographs but some drawings--of each species as it comes up.
