Transient Killer Whales

Michael Colahan, Island Adventures Whale Watching and Pangea Pictures

• More fluid social organization; smaller temporary pods

• Diet is mostly marine mammals, especially harbor seals

• Cover larger distances than residents

5

Offshore Killer Whales

Craig Matkin

Major Threats for Salmon

• Habitat

• Hatchery

• Hydropower

• Harvest

• Predation

5

Habitat• Degraded conditions

• Diminished forage fish pops

• Fish passage barriers

Hatchery• Reduced production for

hatchery reform and/or due to funding

6

Hydropower

• Reservoir effects/travel time

• Concentrate (funnel) fish

• Survival improvements

Harvest

• Declined significantly

Predation

• Some predators shown to be consuming large proportion of fish runs in some places

• Harbor seals, sea lions, seabirds, predatory fish

Overview: Vessels Working Group

Todd Hass, PhD

Chair, Vessels Working Group

Puget Sound Partnership

May 1 2018

• Salish Sea is ‘critical habitat’ for SRKWs

• Vessels—from small craft to ships—

produce underwater noise, masking

echolocation & communication

• Presence of vessels may displace from preferred areas, induce switches to energetically costly behaviors

• BC shipping traffic has been on the rise and likely to grow

• Recreational/commercial whale watching has expanded

Categorizing threats

Mechanical

• Ships: lower frequencies interfering with communication and compensation with louder calls• Boats: higher frequencies masking echolocation, impairing prey-finding and capture

Electronic/sonar• Common 50 kHz frequency of echo-sounders overlaps with orca echolocation

Categorizing vessel noise and effects on SRKWsTypical sources and acoustic frequencies of underwater masking noises

• SRKW recovery far better with 15% > prey and 50% less noise, than 30% > prey (Lacy et al. 2017)• Models suggest SRKWs lose foraging time due to vessel/noise avoidance behavior to ships and boats—3hr and 15min per day—respectively (ECHO-Tollit et al. 2017)• By vessel class: 15% of ships produce about half the low frequency noise (Veirs et al. 2018 in press)• Transport Canada noise mitigation model available in 2 wks

Scientific “currencies” for targeting and measuring success of vessel mitigation

Regional experts from shipping, boating and specialist groups from US/Canada

Composition of Vessels Working Group

Large vessels Small vessels Specialists

Ports Recreational Acoustics

Shipping Whale watchers Vessel design

Ferries Safety/education Vessel traffic management

Pilots Enforcement SRKW behavior

Vessels Working Group not starting from scratch: stage set to ‘form, storm, norm and perform’

• (and…) solid foundation of scientific understanding

• (but…) shared discussions of pros, cons and other considerations of options between groups—limited to date

• (so…) opportunity to ‘identify, research and analyze potential actions and formulate draft recommendations for the Task Force’ is ripe and timely

RECOVERY PLAN- 2008

Species in the Spotlight- most at risk for extinction• Contaminants and health• Protect whales from harmful

vessel impacts• Target recovery of critical prey• Protect important habitats• Raise awareness and inspire

stewardship

Other ongoing actions include• Oil spill response planning• Transboundary coordination

ACTION PLAN 2016-2020

CONTAMINANTS AND HEALTH

• Health workshops 2015, 2016, 2017

• Discuss needs, strategies and priorities related to:

• What is causing decreased reproduction?

• What is causing increased mortality?

NOAA- J16

CONTAMINANTS AND HEALTH

• Health database

• Photogrammetry and links to

biomarkers and prey

• Track and sample animals of

interest (fecal, breath)

• Contaminants trends

• Body condition and blubber

thickness/content

• Stranding investigations-

causes of death, disease and

pathogens

• Puget Sound Partnership Action Agenda to restore Puget Sound

• Series of workgroups in 2013 with EPA- PBDE removal in wastewater, transport/fate, need to establish threshold

• Report and recommendations from PBDEs working group with EPA and WA state agencies

CONTAMINANTS AND HEALTH

•Prohibits vessels from approaching killer whales within 200 yards

•Prohibits vessels from parking in the path within 400 yards

In 2011, NOAA Fisheries issued federal vessel regulation to reduce disturbance from vessels to SRKWs:

NOAA committed to assessing effectiveness and impact

PROTECT FROM HARMFUL VESSEL IMPACT

Recommendations from NOAA Tech Memo:

• Continued and expanded enforcement,

Soundwatch/Straitwatch monitoring, and

education/outreach

• Compare the behavioral and acoustic effects

of different boat activity patterns to determine

the vessel behaviors with the highest impact

• Improve estimates of the energetic cost of

reduced foraging opportunities

• Support Canada establishing similar vessel

regulations to improve protection and

compliance
