Abstract Excerpt:
Yukon River Chinook salmon (Oncorhynchus tshawytscha) returns have declined dramatically since the late 1990s, leading to severely restricted subsistence harvests and closures of commercial and sport fisheries in attempts to meet spawning escapement needs (Estensen et al. 2015). Despite extraordinary harvest reductions, pervasive failures to meet escapement objectives in the Yukon River and other Alaskan systems have occurred throughout recent years (Munro and Volk 2014). Although causes of this production decline are unclear, concurrent declines throughout Alaska (ADF&G 2013) have placed emphasis on ocean conditions and the marine life history stage of Chinook salmon.
