Skeena Sockeye In-River Run Reconstruction Analysis Model and Analysis Results for 1982-2009

This report provides a brief outline of a Skeena Sockeye In-River (SSIR) run reconstruction model built to combine information on run timing and escapements for Skeena sockeye sub-stocks with catch estimates for each sockeye fishery within the Skeena watershed. The model is similar to those developed for the Fraser River sockeye fisheries within the Fraser watershed except that the Skeena model moves fish forward (upstream) through the fisheries and subtracts sockeye catches from estimates of the number of sockeye entering the Skeena River each day. The Fraser Chinook and sockeye models reconstruct the runs entering the Fraser River by adding catches to daily estimates of escapement for each sub-stock.
