Research finds some Pacific salmon migration out of sync with food supply
VANCOUVER — Climate change is knocking some Pacific salmon out of alignment with the growth of the ocean plankton they eat to survive, new research says.
In the largest data set ever gathered on the timing of juvenile salmon migration, research found the changing climate is causing some salmonpopulations to migrate earlier out of step with plankton blooms that are also affected by changing weather patterns.
Lead author Sam Wilson said that as climate change continues the two will match less and less, putting salmon survival at risk.
“The coastal ocean is changing in one way and Pacific salmon are changing in a myriad of other ways and those ways don’t always align,” said Wilson, a post-doctoral researcher in the salmon watersheds lab at Simon Fraser University.
