SFI Member Update - 2023 SRKW PROPOSALS
In yet another round of consultation regarding SRKW recovery, the SFI and SFAB are at the table discussing new proposals for the 2023 season. What is evidently an annual review process results in uncertainty, instability, and anxiety for each of the small coastal communities that depend on predictable fishing related tourism. Implementation of an annual process that does not seem to bring any new or relevant information yet proposes additional restrictions undermines the social, cultural, and economic fabric of communities that are reliant on the recreational fishery for their wellbeing. Entire communities like Port Renfrew, or in areas that have already been severely restricted or had fishing closures imposed like that in and around Vancouver, continue to suffer the compounding effects of stacking layers of unproven fishery management measures. These new proposals ignore the fact that the SRKW population is currently stable, and that prey availability has been proven not to be the issue it was once thought to be. In both US and Canadian waters studies* show that the abundance of Chinook during the periods that SRKW are present are between 11 and 22 times necessary to satisfy nutritional requirements of the whales. Rather than continue to experiment at the expense of predictability, now would be a time to ensure that relevant assessment of the existing measures takes place and that the effectiveness of the measures in aiding in SRKW recovery is determined. A pause in adjustments, changes, or additions to SRKW measures will also reduce the cycle of uncertainty and anxiety created in coastal communities on what is now an annual basis. Focus should turn to determining what is effective, or not, here and what is working, or not, in adjacent Washington state waters to benefit SRKW recovery.
Or, BC would do well to follow the lead of Washington state, who have addressed the challenges of improving the environment around a mobile species like SRKW and their equally mobile prey. Rather than implement static sanctuary areas they focus instead on applying consistent, effective avoidance zones for ALL small vessels that may disrupt foraging and other important activities for SRKW. BC’s spatial measures may look good on a map but on the water and observing whales along our coast it is clear that SRKW and all whale movement is challenging to predict. The BC areas set aside for the SRKW are rarely used. It is our hope that sufficient, consistently enforced, and effective mobile sanctuaries or dynamic avoidance zones, are implemented to allow whales room to feed, socialize and reproduce wherever and whenever they are in BC waters.
The flawed process that is now unfolding annually regardless of the quality, applicability or quantity of new information available, has unfortunately included announcement of another potentially biased survey. This survey, like the one released in 2018, is leading and offers participants only a choice of support rather than options to object or raise concerns. And, the approach to establish avoidance zones or an “avoidance bubble” strategy is nowhere to be seen. We encourage anglers to participate in the DFO survey and to comment, where possible, with support for an avoidance zone of at least 400 m for all small vessels as an effective strategy and alternative to fixed spatial closures.
The SFAB is currently engaged in focussed discussions with DFO Marine Mammal staff to ensure that the voices of local communities and anglers are heard. It is our ongoing hope that this feedback will be properly considered and acted upon.

Provide Input on Recovery of Southern Resident Killer Whale Management Measures for 2023 through an Online Survey
The Government of Canada would like to hear from you. On January 19th, 2023, an online survey was launched to seek feedback on the potential management measures to help the recovery of the of Southern Resident Killer Whales.
Since 2019, the Government of Canada has implemented a suite of measures each year to protect and further support the recovery of this iconic Pacific whale population. These measures address key threats to the recovery of this population, including reduced quantity and access to their prey, and increased noise and disturbance in their habitat.
Your ideas and feedback will help us refine the potential management measures and help us understand potential implications of the options being considered. As such, we invite you to review the potential management measure options for 2023, and submit your comments to help inform this year’s approach. The public survey is available on the Fisheries and Oceans Canada website until February 19, 2023. Please use this link: https://www.pac.dfo-mpo.gc.ca/consultation/fm-gp/srkw-eprs/2023-srkw-management-gestion-ers-eng.html to access the survey.
If there are any questions about the Southern Resident Killer Whale management measures, please contact DFO.SRKW-ERS.MPO@dfo-mpo.gc.ca

May 5, 2022 - Southern Resident Killer Whale 2022 Management Measures Announced
News Release and DFO document regarding the 2022 SRKW measures.
SFI Member Update - May 6, 2022
2022 SRKW MANAGEMENT MEASURES ANNOUNCED
The 2022 SRKW management measures were announced Friday of last week and can be found at this link. These measures represent significant gains, maintenance of, or moderate losses in fishing opportunity dependent on the area on the south coast.
While static closures continue to be a component of DFO measures, the SFI does not support the approach as a means to protect a highly migratory and fast moving species like Killer Whales or their access to an equally migratory prey, salmon. The use of static closures or sanctuaries\no go zones will not provide any measurable protection to SRKW and limits the scope and area that protections are provided to the whales when they are in our waters. Although static closures and sancturaries continue to be implemented it would be more effective if there were presence or no presence triggers that could be applied to close and open areas so that activities in and around these zones could take place at times when whales are not present. In addition to the highly moveable and migratory habits of thier prey, there is increasing evidence that the habits of SRKW and other whales are changing and adapting. To have rigid parameters on confined area closures is ineffective for the whales.
The idea that prey availability is a limiting factor in the ability for SRKW to increase their population levels has been debunked by many recent studies released by UBC, Washington Department of Fish and Wildlife and DFO scientists. These studies indicate that the abundance of Chinook when and where the SRKW are feeding in the Salish Sea, which includes the Straits of Juan de Fuca and Georgia, is significantly more than enough to support SRKW while they are in the area. Rather than prey availability restrictions by area or activity, we hope to see prey accessibility aided through use of mobile avoidance zones at the appropriate distances, currently 400m, to minimize distractions due to noise or proximity. The mobile avoidance zones are an effective tool that provides protection from competition for prey (aka prey accessibility) and physical disturbance wherever the whales are. It is the use of this strategy and changing habits of the whales that is likely responsible for any gains towards recovery and growth.
LOCAL AND TRADITIONAL KNOWLEDGE HELPING WHALES AND COMMUNITIES
In the south western portion of BC's SRKW habitat, notably Juan de Fuca Strait and the Port Renfrew area, the 2022 measures reflect the value and efficacy of the SFAB in bringing together community voices and interests, including collaboration with local indigenous communities, to provide a local perspective at well attended and organized public meetings. We offer our thanks to DFO for respecting the local SFAB process and considering the advice provided at those sessions, to the SFAB representatives who advocated for those local processes to occur with senior levels in DFO, and to those who co-chaired the sessions.
Southern Gulf Islands and the mouth of the Fraser River are locations where more research is needed to identify both how much and when the SRKW use these areas for foraging and before new management measures are added or created that may or may not have a positive effect. As example, large portions of Pacifc Fishery Management Areas (PFMA) 20-3 and 20-4 were closed on the basis that it was believed that they were important foraging areas only to find that those beliefs did not stand up to scientific scrutiny. It is frustrating and damaging to perception and sustainable opportunity that DFO continues to implement optical solutions that are designed to placate vocal interests. These window dressing solutions have the potential to harm local residents and businesses unecessarily yet do not benefit the whales.
We look forward to continuing to participate in consultation regarding SRKW in the hopes that good science, common sense and respect for local input can prevail over optics in efforts to effectively and meaningfully improve the circumstances for whales on our coast.
February 28, 2022 - SRKW FISHERY MANAGEMENT MEASURES UPDATE AND SURVEY
SFAB participants in DFO and Transport Canada Technical Working Groups formed to discuss development of SRKW managemenent measures explained that it was critically important that communities and stakeholders in each of the areas where changes or proposals are being considered were properly consulted. As a result and in response to that request a series of meetings coordinated by the DFO SRKW team have taken place in recent weeks.
DFO has also made a survey available for anyone interested in the subject to learn more and to provide feedback. If you choose to participate in this SRKW survey we encourage you to review the materials below, gathered feedback from SFAB and local community representatives regarding each of the area proposals.
SRKW Fishery Management Proposal Survey - 2022
Deadline for respondents to complete the survey is March 2, 2022.
You will note:
There are 24 questions covering several areas of interest under consideration for management measures.
Many questions allow drop down comment boxes for respondents to provide additional comments – you can offer more detailed responses or if a question is unclear, you can provide comment based on your understanding of the question. Please provide written comments in the drop-down boxes, rather than simply selecting a yes or no answer. This is your opportunity to share your knowledge.
If you prefer to note in the comment section that you support the alternative SFAB options noted in the attached maps, you can do so.
For some locations, there is more than one option under consideration. Please comment on each, and if there are options not captured in those offered, you can provide alternatives and rationale. Be advised, the SFAB developed alternatives which include updated maps.
In the section asking if you have recommendations for any temporal changes (Question 12) note that this refers to considerations for placing triggers on either closing a fixed sanctuary area or opening one dependent on observed sightings of SRKW. In other words, these areas would remain open when SRKW are not present but closed when they are.
The SFAB proposed adaptive management measures that would apply when whales are present but are removed when they are not. If you support adaptive management, please comment within the survey.
The 400m and 1km avoidance and awareness protocols should, wherever possible, continue to be the primary tool used, not closures.
When a fishing closure is implemented, it should be a “no salmon fishing closure” and not a “no fin fish fishing closure”.
Included in this update are the local SFAC input provided to DFO for reference, we summarize those by Area as follows:
Area 20/121 SFAC (Port Renfrew): More Info
Option 1A is preferred for Area 20-1, only if the SFAB recommendations are supported
Document 1 - provides the local SFAC Motion for Area 20 with supporting rationale for alternative options
Map of Hybrid Options noting areas open for Salmon Fishing – other sanctuary areas closed would be salmon closures and not fin fish closures, to allow for halibut fishing.
Document 2 – provides the local SFAC Motion for Area 121 hybrid alternative options
Option 2B is preferred for Area 121 Swiftsure Bank, only if the SFAB recommendations are supported
Area 19 SFAC (Victoria/Sooke): More Info
Local SFAC does not support either option 1 or 2 proposed by DFO
Document 3 – provides an alternative map outlining a box sanctuary closure around a forage hot spot identified offshore from Beachy Head. This proposal seeks to leave open for Salmon fishing the shoreline waters important to recreational fishing, while providing closure protection for the offshore forage area
The Area 20-3 and 20-4 existing SRKW closed to fishing areas from 2020 and 2021 have now been identified as low value to SRKW recovery based on the SRKW Prey Availability TWG materials presented, therefore they should not be re-implemented for 2022 and beyond.
Area 18 SFAC (Gulf Islands): More Info
Local SFAC advice was for no further expansion of existing closures, application of adaptive management measures, and supports Option 1 only;
Adaptive Opening and Closing – strongly support the adaptive timing closing the area to fishing when the SRKWs show up in the area. And, strongly support adaptive re-opening of the closed to salmon fishing area once SRKWs have left the area - recommend a 14 day no sighting (whale presence) window for the re-opening to be triggered
Increased utilization of continuous marine VHF broadcasts to alert mariners of SRKW presence in these areas to support Adaptive Management
If DFO adopts additional closure areas, local SFAC advises a 500m shoreline “open to salmon fishing corridor” as noted in attached map for areas:
(i) at Collinson Point, Galliano Island, (ii) the south shore of South Pender Island and (iii) the east shore of Moresby Island
Area 29 SFAC (Fraser River Mouth): More Info
After significant consultation with the Vancouver public, the overwhelming consensus for the Mouth of the Fraser River is for Option 1, status quo.
Option 2 or 3 would have devastating consequences to what little is left of the local fishery following years of significant Chinook Management Restrictions
These options also push recreational fishers into the commercial shipping lanes creating a safety hazard
Currently there is a long-standing closure for salmon fishing in Areas 29-6, 29-7, 29-9, 29-11, and 29-12 .
Proposed SRKW fishery measures are layering impacts on top of recent Chinook restrictions (April 1 to August 31). If SRKW are present, these significant closures are more than adequate to protect their migration in and out of the area and any foraging that may occur
Local SFAC strongly suggests adaptive measures, supported by education & awareness, plus continuous marine VHF broadcasts to advise mariners when SRKW are present. Fisheries Notices and VHF broadcasts are effective tools to implement short term adaptive measures (spot closures) when implemented and removed
Local SFAC questions what science is being utilized to guide the proposed fishery measures, as there is no focal follow study and actual recent scientific analysis of forage activity
Vancouver Island Chambers of Commerce:
A delegation of Executive Directors from various Vancouver Island Chamber of Commerce attended one of the local SFAC meetings, presenting their views on the social and economic consequences of the proposed fishery management measures. Presentation notes
The SFAB encourages participants to complete the survey particularly if they are able to share local knowledge and expertise.
October 12, 2021 - Southern resident killer whales encounter higher prey densities than northern resident killer whales during summer (cdnsciencepub.com)
UBC Press Release: No apparent shortage of prey for southern resident killer whales - October 12, 2021
Authors: Mei Sato, Andrew W. Trites, and Stéphane Gauthier
Abstract
The decline of southern resident killer whales (Orcinus orca) may be due to a shortage of prey, but there is little data to test this hypothesis. We compared the availability of prey (Chinook salmon, Oncorhynchus tshawytscha) sought by southern residents in Juan de Fuca Strait during summer with the abundance and distribution of Chinook available to the much larger and growing population of northern resident killer whales feeding in Johnstone Strait. We used ship-based multifrequency echosounders to identify differences in prey fields that may explain the dynamics of these two killer whale populations. Contrary to expectations, we found that both killer whale habitats had patchy distributions of prey that did not differ in their frequencies of occurrence, nor in the size compositions of individual fish. However, the density of fish within each patch was 4–6 times higher in the southern resident killer whale habitat. These findings do not support the hypothesis that southern resident killer whales are experiencing a prey shortage in the Salish Sea during summer and suggest a combination of other factors is affecting overall foraging success.

July 21, 2020 - 2020 Management Measures to Protect Southern Resident Killer Whales
Regarding the Government of Canada’s 2020 Management Measures to Protect Southern Resident Killer Whales, several outreach and education products have been made available by joint efforts of Transport Canada, Fisheries & Oceans Canada, Parks Canada, Environment & Climate Change Canada. These materials are made available here and provide information on this 2020 management measures and are intended to increase awareness of the rules.
2020 Southern Resident Killer Whale management measure videos:
Outreach and education materials with as many individuals and groups as possible will raise public awareness and increase the number of boaters/vessel operators and fishers who understand their responsibilities on the water. Combined efforts will help increase compliance on the water and support the recovery of the endangered Southern Resident Killer Whale.
Please note, from August 1 to October 31, 2020, there will be no recreational or commercial salmon fishing allowed in Southern Resident Killer Whale key foraging (feeding) areas found in the Strait of Juan de Fuca and Gulf Islands (located within Southern Resident Killer Whale critical habitat).
Be Whale Wise is a partnership between Canadian and U.S. organizations and agencies and the material provides information on rules and guidelines for boating around marine mammals and birds in both Canadian and U.S. waters.

Whales Initiative: Protecting the Southern Resident Killer Whale
June 1, 2020
A reminder that as of June 1, 2020, Transport Canada’s Interim Order for the Protection of Killer Whale (Orcinus orca) in the Waters of Southern British Columbia, 2020 is in effect including:
Minimum 400 metre approach distance (year-round)
Vessels are prohibited from approaching any killer whale within a 400-metre distance in all southern BC coastal waters between Campbell River and just north of Ucluelet.
Certain whale watching and ecotourism companies who receive an authorization from the Minister of Transport, will be allowed to view non-Southern Resident Killer Whales from 200 metres, in recognition of their ability to distinguish between ecotypes. Authorized companies will have a purple flag with ‘AV’ denoted in the middle. This measure is in addition to the 200-metre approach distance for all killer whales in Canadian fisheries waters in the Pacific Ocean and BC, other than in the area described above.
Interim Sanctuary Zones (June 1 – November 30)
Interim Sanctuary Zones will be in effect off Pender Island, Saturna Island and at Swiftsure Bank.
No vessel traffic and no fishing will be allowed in these areas, with some exceptions including: vessels accessing local residences, business or services; vessels in distress or providing assistance to a person or vessel in distress; vessels avoiding immediate or unforeseen danger; Indigenous peoples exercising existing rights. Additionally, a 20 metre corridor along the shoreline of the Pender and Saturna Island Interim Sanctuary Zones has been created to allow those in human-powered vessels to transit safely through these areas.
Additional measures:
Fisheries Management Measure
Area-based fishing closures will be in effect in the Juan de Fuca Strait and Southern Gulf Islands for recreational and commercial salmon fisheries through the summer and fall.
More information on specific dates will be announced in June.
Fishers are also asked to stop fishing within 1,000 metres of all killer whales.
Best practices to Be Whale Wise
Reduce speed to 7 knots or less when within 1000 metres of the nearest marine mammal.
Turn off echo sounders and fish finders when safe to do so.
Place engine in neutral idle and allow animals to pass if you find yourself within 400 metres of a killer whale.
ECHO Program (http://www.portvancouver.com/echo) large commercial vessel measures
Haro Strait and Boundary Pass voluntary vessel slowdown (potential effective date June 1 – Oct 31, based on whale presence)
Large commercial vessels slow down to speed through water targets: 11.5kn (bulkers, tankers, general cargo) or 14.5kn (containers, car carriers, cruise)
Strait of Juan de Fuca voluntary inshore lateral displacement (June 1 – October 31)
Inshore vessels (tugs) move further away from shore into lateral displacement zone

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:
A mandatory 400 metre approach distance for all killer whales throughout SRKW critical habitat, with the ability of the Minister of Transport to authorize commercial whale watching companies to approach other killer whale ecotypes to 200 metres, subject to certain conditions.
Mandatory interim sanctuaries with restrictions on fishing and vessel activity in Swiftsure Bank, south Saturna Island and west of Pender Island.
Effective August 1 – October 31, 2019:
Mandatory area-based fisheries closures for recreational and commercial salmon in key foraging areas.
Other actions to take while SRKW are present in BC waters in greater numbers:
A voluntary go slow and fishery avoidance zone, asking boaters to reduce their speed to less than 7 knots and avoid fishing when within 1,000 metres of a whale in the Enhanced Management Areas that have been identified through the Gulf Islands, the Strait of Juan de Fuca and the Mouth of the Fraser River.
Voluntary measures asking vessel operators to reduce noise by turning echo sounders off when not in use and turning their engines to neutral idle when within 400 metres of a whale.
The GOC is seeking help to get information on these measures out to those who are operating vessels in the area.

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.

Habitats of Special Importance to Resident Killer Whales (Orcinus orca) off the West Coast of Canada
---
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.
