The sad story of an orca carrying her dead calf for 17 days off the Washington coast this month has garnered global attention to the plight of killer whales in the region. It has also highlighted the steep decline in the region’s salmon stocks, the resident orcas’ sole food source.
Malnutrition is thought to have led to declining fertility and low survival rates in juveniles in the pod to which the orca belongs. That is because the availability of Pacific Ocean salmon has been trending low for the past decade.
The total pounds of chinook salmon caught off the Oregon coast in 2017 fell 40% compared with the year before, according to Oregon Department Fish & Wildlife (ODFW) data. Between 2014 and 2017, total pounds caught dropped 80% and the value of the catch dropped 72% to $5 million.
