• December 29, 2012 update – Second endangered southern resident tagged K25. 

February 20, 2012 – Endangered southern resident J26 tagged and the tag only stayed on for 3 days.

January 22, 2012 update to the December 10, 2010 blog item below:  Approval granted to limpet tag the endangered southern resident killer whales. See news items at the end of the blog. 

The American “Northwest Fisheries Science  Center” (NWFSC) has applied for expansion of their permit to satellite tag endangered and threatened whales with airguns, including the endangered Southern Resident killer whale population and the threatened Northern Residents and Transient populations (the range of all these whales very much includes British Columbian waters).

It is the opinion of many involved in whale research and conservation that the impact of the airgun tagging far out weighs any benefit to the whales. There are other ways to get data on the movement of killer whales e.g. acoustic tracking and collaboration with researchers who have been studying these whales more extensively than NWFSC.


It is my opinion that the tagging cannot provide data that will help reduce the threats of toxin accumulation, prey availability, disturbance or noise so – why do it?  The photos here indicate just how invasive these types of tags are.

Below, I also include a letter from the North Island Marine Mammal Stewardship Association (NIMMSA) in which they powerfully express their concerns about the tagging.

If you too are concerned about the merit of this tagging program, please help in creating awareness. Share this blog on Facebook; do what you want with the images (help them go viral) and provide coment via this link before December 23rd, 2010.

Close up of the tag.
