Reconstruction of British Columbia sockeye salmon (Oncorhynchus nerka) stocks : 1970-1982 / P.J. Starr, A.T. Charles, and M.A. Henderson.: Fs97-4/1780E-PDF
"A coastwide assessment of all British Columbia sockeye (Oncorhynchus nerka) stocks for the period 1970-1982 is made in this report. Data inputs used include escapement (number and timing) by stock, catch by area, and known migratory routes for each stock. Separation of catch into component stocks is made proportionate to the escapement of each stock following a procedure known as run reconstruction. In general, all major B.C. sockeye stocks show no discernible trend or are increasing in the period covered by the report. Some minor stocks, particularly in the Queen Charlotte Islands, the Central Coast and Johnstone Strait, appear to be decreasing. Limitations in the quality of the data, particularly in escapement counts, make the assessment of stocks in remote areas uncertain"--Abstract, page v.
