Description
Summary:indicators of climatic and oceanic shifts in the North Pacific Ocean, 1922–2000 N. Pac. Anadr. Fish Comm. Bull. 5: 177–182. Abstract: Climate regime shifts can alter the community structure of marine species in the North Pacific Ocean. In this study, we use a regime shift detection algorithm to determine whether regime shifts are recorded as shifts in the mean fish length indices at the smolt, juvenile, immature, and mature life stages based on measurements of increments on scales of adult age-2.2 sockeye salmon (Oncorhynchus nerka) that returned to the Karluk River, Kodiak Island over a 77-year time period (1924–2000). Fish length was expected to increase with cool-to-warm
