History of the Fishery and Summary Statistics of the Sockeye Salmon, 'Oncorhynchus nerka', Runs to the Chignik Lakes, Alaska, 1888-1966

摘要

Annual runs of sockeye salmon to the Chignik Lakes, Alaska, decreased from an average of 1.9 million during the period 1922-39 to an average of 0.9 million during the period 1949-1966. In order to study the dynamics of the runs' historic catch, escapement and age, structure data were compiled by spawning stock and brood year. The history of fishing and management of the runs from inception of the fishery until 1966 is described. Results of the study were used to construct parent-progency relationships that formed the basis for a management strategy to restore the runs to their former level of abundance.
