Biological characteristics and population status of anadromous salmon in south- east Alaska. Gen. Tech. Rep. PNW-GTR-468. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 255 p. Populations of Pacific salmon (Oncorhynchus spp.) in southeast Alaska and adjacent areas of British Columbia and the Yukon Territory show great variation in biological characteristics. An introduction presents goals and methods common to the series of reviews of regional salmon diversity presented in the five subsequent chapters. Our primary goals were to (1) describe patterns of intraspecific variation and identify specific populations that were outliers from prevailing patterns, and (2) evaluate escapement trends and identify potential risk factors confronting salmon populations. We compiled stock-specific information primarily from management research con- ducted by the Alaska Department of Fish and Game.
