This page has become an archive of relevant and important documents on the subject of Southern Resident Killer Whales (SRKW). We update this page periodically, add as new details become available and will retain a chronological order for additions.

West Coast salmon fisheries catch a small share, leaving prey for Southern Residents.
Mobile avoidance sanctuaries, chinook enhancement, specific predator control and habitat rehabilitation can help both SRKW recover and for coastal communities to thrive. Watch the Coastal Alliance and SFI clip above and visit SRKW.org for more information.
WHALES INITIATIVE: PROTECTING SOUTHERN RESIDENT KILLER WHALES – INFORMATION BROCHURE
May 2019 – The Government of Canada (GOC) has taken steps to protect and recover the SRKW population. There is recognition that SRKW face imminent threats to their survival and recovery and that immediate action is required.
On May 10, the GOC announced 2019 SRKW recovery measures. New measures for vessels to follow include:
Effective June 1 – October 31, 2019:
Effective August 1 – October 31, 2019:
Other actions to take while SRKW are present in BC waters in greater numbers:
The GOC is seeking help to get information on these measures out to those who are operating vessels in the area.
For more information on the 2019 measures please follow these links:
Protecting species at risk is a responsibility shared by all Canadians and the federal government is committed to working with Indigenous people, provincial and territorial governments, and relevant industry stakeholders to achieve this goal.
SOUTHERN AND NORTHERN RESIDENT KILLER WHALES
Discussion and research continues on the subject of Southern Resident Killer Whales. Of note and interest, Washington Department of Fish and Wildlife recently published findings regarding prey availability for SRKW in Juan De Fuca Strait. Findings are relevant to our waters and can be read here: Fishery Effects on SRKW – Jan28, 2019
The Standing Committee on Fisheries and Oceans Canada was tasked to study the Situation of Endangered Whales and provide a report – December 2018.
The Standing committee heard from many witness over the fall of 2018 regarding whales, SRKW, Beluga and Right Whales, in Canadian waters. Owen Bird and Martin Paish, SFI, appeared in Ottawa on October 30 and provided comments about SRKW and consultation to date. The linked report provides recommendations including ensuring that socio-economic information is gathered and properly considered, that local and traditional knowledge is incorporated in findings, that enhancement of Chinook stocks be initiated and specific predator control plans be developed and implemented.

And, find some relevant links and documents about Southern and Northern Killer Whales at the bottom of the page and as follows:
There has been discussion about the health of Southern Resident Killer Whales over many years, a symposium in the fall of 2017 and associated comments by the Fisheries Minister at the time, the Honourable Dominic Leblanc, signaled an interest and a call to action by government to make changes to the circumstances and environment that SRKW currently find themselves.
While the approach to Southern Resident Killer Whale recovery efforts will likely be multi-faceted there would seem little doubt that the recreational sector needs to be aware of the issue and prepared to modify activities so that we can be a part of the recovery of these magnificent animals. While scientific studies agree that ceasing harvest will not provide the desired increase in abundance of Chinook salmon for SRKW, there is evidence that increasing production of chinook salmon and addressing marine noise and disturbances should help. Reduction of marine noise can be affected immediately by reducing speeds and agreeing to leave a wide corridor around moving Killer Whales. Increasing numbers of Chinook salmon, Killer Whales preferred food, can take place relatively quickly and can be augmented and enhanced through use of ocean pens to temporarily hold and feed juvenile Chinook. The survival rates of juvenile salmon held even for a month in an ocean pen is as much as 10 times higher, from 3% to as high as 30%, than that of fry or smolt entering the ocean directly from estuarine or river environments. A combination of reduced interaction or interference with the whales as they try to feed and forage and a concerted effort to increase production of Chinook salmon generally and particularly using ocean net pens to briefly hold and feed juveniles would by, many accounts, go a long way to aiding in the recovery of these fantastic animals.
We will dedicate this space to provide updates and links to important and relevant information on the subject.
