Development of Habitat Preference Criteria for Holding Adult Spring Chinook Salmon

摘要

Fish habitat criteria, in the form of suitability curves, have been unavailable or inappropriate for certain anadromous salmonid life history stages in Pacific Northwest streams. Among the unavailable criteria were suitability curves for the adult holding stage of spring chinook salmon. The U.S. Fish and Wildlife Service (USFWS) and the Washington Department of Fisheries recognized this information gap and felt that it hindered their ability to protect spring chinook runs from manmade habitat alterations.
