Declining salmon productivity trends

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.

Phytoplankton phenology as a driver of salmon dynamics

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.
