Forecasting Southeast Alaska pink salmon harvest from juvenile salmon data: extension of models

The Southeast Coastal Monitoring project has conducted monthly sampling surveys to collect data associated with juvenile salmon as they pass through migration corridors to the Gulf of Alaska. These surveys are conducted from May to August after the high-mortality periods of both freshwater incubation and early marine nearshore residency, and provide information on year-class strength that can be used with associated environmental data to forecast abundance of the returning adult salmon in subsequent years. Pink salmon catch data from these annual surveys have been used to develop models that predicted SEAK pink salmon harvests.
