In this study, we tested the hypothesis that North American pink (Oncorhynchus
gorbuscha) and chum (O. keta) salmon stocks have experienced recent declines
in productivity (i.e., the number of adult recruits returning per spawner) by
investigating temporal and spatial trends in productivity of 99 wild North
American pink and chum salmon stocks.
In this study, we investigated how multiple ecological pathways potentially link
climate and oceanographic processes to wild Oregon coho salmon (Oncorhynchus
We analyzed the effects of the spring bloom timing on pink salmon productivity
(adults produced per spawner) in the Northeast Pacific Ocean to better
understand the mechanisms linking biological oceanographic conditions to Pacific
salmon population dynamics.
