Description:

Increasing evidence for relationships between Pacific salmon (Oncorhynchus spp.) production and shifts in climate conditions has renewed interest in processes governing yearclass strength in salmon (Beamish 1995). However, actual links tying salmon production to climate variability are understood poorly due to a lack of adequate time-series data (Pearcy 1997). In addition, mixed stocks with different life history characteristics confound attempts to accurately assess growth, survival, distribution, and migratory rates of specific stocks. Synoptic time series of ocean conditions and stock-specific life history characteristics of salmon are needed to adequately identify mechanisms linking salmon production to climate change. Until recently, stock-specific information relied on labor-intensive methods such as coded-wire tagging (CWT; Jefferts 1963). However, advances in mass-marking methods using otolith thermal marks (Hagen and Munk 1996) now offer an opportunity to examine growth, survival, distribution, and migratory rates of specific stocks.
