Southern Resident Killer Whales:  Is their Time Running Out?

A Population Viability Analysis published in 2017 found that prey limitation was the most important factor affecting population growth in Southern Resident killer whales, but reduced foraging efficiency due to vessel traffic and contaminant burden all combine to inhibit recovery. To meet SRKW recovery targets through prey management alone, Chinook abundance would have to be sustained near the highest levels since the 1970s, but combining more realistic prey management goals with other initiatives could also lead to recovery. This presentation examines immediate and long-term Chinook fisheries management issues that affect Southern Residents and Chinook salmon in the Salish Sea, including the status of Canadian Chinook stocks and the reasons for this status. Work is currently underway in Canada to examine sanctuaries, fisheries impacts, and reduce vessel noise and disturbance. These and other initiatives to recover Southern Residents will be discussed.

 

The Winter, 2019 Huxley Speaker Series is co-sponsored by Huxley College of the Environment and WWU's Salish Sea Institute, presenting a 10-week series on issues facing the Salish Sea.
