CORVALLIS, Ore. - The first comprehensive guide to Oregon's freshwater fishes has been published by the Oregon State University Press.
Written by Professor Emeritus Douglas Markle in the Department of Fisheries and Wildlife at Oregon State, the guide includes tips on identifying the state's 137 known species and subspecies, along with photos and illustrations of native and non-native fish.
"A Guide to Freshwater Fishes of Oregon" is available in bookstores, by calling 1-800-621-2736, or by ordering online at osupress.oregonstate.edu
The guide includes information about Oregon's most iconic fishes - including Chinook and coho salmon - as well as those species not as well-known, such as sculpins and minnows. Markle notes that the number of introduced, non-native fishes continues to increase and "they often are responsible in part for the decline of native fishes."
"The book is a great guide for anglers and others who may encounter a fish that they cannot easily recognize," said Marty Brown, marketing coordinator for the OSU Press. "Many groups of Oregon fishes are difficult to identify because of their size, diversity of forms, or lack of study, and there are ongoing debates about the actual number of species and subspecies of fish in the state."
The guide covers fish both large and small. The white sturgeon is Oregon's largest freshwater fish, reaching sizes of up to 19 feet and 1,800 pounds, and it is the most long-lived reaching estimated ages of close to 100 years. Among the smaller fish are minnows, which are the largest family of fishes in Oregon, and include such species as the Oregon chub and Umpqua chub - species only found in this state.
Markle is a long-time faculty member at Oregon State who parlayed a childhood interest in aquarium fish into a career teaching and conducting research on deep-sea fishes, coral reef fish, and a variety of freshwater fishes.
In addition to the many color photographs in "A Guide to Freshwater Fishes of Oregon" are numerous illustrations by well-known fish artist Joseph R. Tomelleri.
