    Abstract
    Coho Salmon (Oncorhynchus kisutch) are a species of great social and economic importance for commercial, sport, personal-use, and traditional harvest. We explored factors influencing Auke Creek Coho Salmon smolt production, growth, and marine survival. We analyzed 35 years (1980-2014) of data collected at the Auke Creek Research Station weir in Juneau, Alaska. This extensive data series allowed for an analysis of Auke Creek Coho Salmon growth and survival that is not possible elsewhere. Creek flow best explained variation in smolt-per-adult production. Analysis of freshwater and saltwater scale growth zones failed to identify a specific growth zone with a significant influence on marine survival. Marine survival had a positive relationship with the magnitude of regional hatchery releases and the Pacific Decadal Oscillation. Changes in climate and hatchery production could have negative effects on survival of Auke Creek Coho Salmon, as evidenced by low returns in recent years associated with anomalously high temperatures in the Gulf of Alaska. The impact of climate change and increased hatchery production should be considered in future management decisions.
