North Pacific Ocean, Oncorhynchus spp., Pacific salmon, run estimates Estimates of Annual Salmon Runs from the North Pacific, 1951–2001
The annual runs of adult salmon (Oncorhynchus spp.) to North America and Asia have been estimated from num-bers of fish in catches and escapements, or catches and estimated rates of exploitation (Rogers 1987). Russian catches reported in metric tons were converted to num-bers by applying average wei...

| Summary: | The annual runs of adult salmon (Oncorhynchus spp.) to North America and Asia have been estimated from num-bers of fish in catches and escapements, or catches and estimated rates of exploitation (Rogers 1987). Russian catches reported in metric tons were converted to num-bers by applying average weights reported in INPFC Sec-retariat (1979). This may result in underestimation of the larger Asian pink and chum salmon runs if competition resulted in smaller body size. Since 1992, Russia has pro-vided salmon escapements from surveys. Russian and Canadian runs for 1992–2000 are from North Pacific Anadromous Fish Commission documents, and very pre-liminary 2001 statistics are from agencies. Pink salmon escapements in Southeast Alaska have been revised (aerial index increased by 2.5) to agree with recent ADF&G sta- |
