Whale “Mugging”?

This information is being provided as a result of recent Humpback Whale / boat interactions having received attention in the media.

As much as it is true that Humpbacks can be astoundingly oblivious of boats,  there are some Humpbacks that occasionally  interact with boats. Both cases have the potential for extreme risk to the whales, and to boaters (see www.SeeABlowGoSlow.org).


Why are there interactions like this? And, what are the best practices for boaters / tour operators when this happens?

We strive to document these interactions and which individuals are involved. While we know of a small number of individual Humpbacks who interact with boats, it appears such interactions may be more likely when the whales are socializing with one another. Not surprisingly, these interactions are more likely when the whales are not directed at feeding.

Is habituation a factor? It may be that some Humpbacks have had previous encounters with boats which perpetuates these interactions. For some Grey Whales, it is believed that they have become accustomed to the interactive whale watching practices in Mexico and thereby approach boats when off the coast of British Columbia.

It certainly is a concern that with each boat interaction, the behaviour may be reinforced and that this increases the risk of collision.

But human behaviour is of course also a concern. Many boaters do not know about the increase of Humpbacks we are so fortunate to have off the coast of British Columbia and just how unpredictable this large whale species can be.

Risk of collision is increased if boaters believe that Humpbacks always know where vessels are.

Baleen whales like Humpbacks do not have the biosonar that toothed whales have. They can surface suddenly after long dives, are often travelling in random patterns, and can be oblivious of boats.

Risk of collision (and habituation) is also increased if the promotion of such interactions leads to increased demand/expectation for close encounters with whales. 

It is a best practices policy of the North Island Marine Mammal Stewardship Association not to promote imagery of whales in close association with vessels. (See the end of this blog for more detail on the NIMMSA Code of Conduct).

The sampling below gives a sense of the human injuries and material damage resulting from collisions. Note that it is now law that collisions and entanglements must be reported to DFO (1-800-465-4336) which will allow for better potential to reduce the risks.

How often do the whales die as a result of collision? Dead whales most often sink to the ocean bottom so this is not known.

What to do if Humpbacks choose to interact with a boat, despite all attempts not to put the whales at risk and contribute to their habituation? Put engines in neutral and ideally turn them off and lift them till the whale(s) are beyond 200m and no longer appear to be advancing toward the boat.

In light of the information above, there is then the moral dilemma for boat operators (and media) about whether to promote such interactions and how they are promoted. The NIMMSA guidelines below and the information at www.SeeABlowGoSlow.org may be of use in this regard.


NIMMSA Marketing and Social Media Guidelines: 

“As stewards, it is important NIMMSA members set realistic marine mammal viewing expectations and educate others on best marine mammal viewing practices. To help achieve this NIMMSA members are expected to follow the below marketing and social media guidelines.

1. Only use images or video in marketing material and on social media that reflects responsible marine mammal viewing in line with this Code of Conduct.

2. Educate clients on the importance of responsible marine mammal viewing and encourage them to only post images or video to social media that reflect operations in line with this Code of Conduct.”

Ocular and Slash – ambassadors of the realities of risk

Another whale has recently been documented with scarring from entanglement. We’ve identified the whale as Ocular, born in 2016 to Slash (BCY0177). Slash has her nickname because, from the first time we saw her in 2008, she had extreme scarring from a large boat propellor. Ocular’s entanglement scarring was first documented last week.

Ocular and Slash – ambassadors of the realities of the risk to whales of vessel strike and entanglement.

They are not exceptional cases. Our research, done in collaboration with DFO, shows that ~1 in 2 Humpback Whales off BC’s coast have scarring from entanglement. This data provides an indication of how serious the risk of entanglement is but does not reveal how many Humpbacks die after becoming entangled.


How many are hit by boats? We don’t know. We see scarring on some survivors but here too, it is not possible to know how many are hit and die as a result of their injuries. There are whales like KC (BCY0291) that we know have been both hit by a boat and been entangled (twice that we know of in KC’s case).

Thankfully, with the new Marine Mammal Regulations it is now law that such interactions with marine mammals must be reported (all incidents of concern to 1-800-465-4336). But increased public awareness is also very much needed. Please see www.HowToSaveAWhale.org.

Content about what to do if you find an entangled whale is summarized below:

  • With great urgency, report the entanglement with location to the DFO Incident Line / VHF 16. 1-800-465-4336.
  • Do NOT attempt to remove any fishing gear or rope from the whale as it risks human and whale safety (has led to human death).
  • If at all possible, remain with the whale at a distance until trained help arrives or another boat takes over tracking, otherwise the chances of relocating the whale are greatly diminished
  • Take whatever video/photos are possible but maintain a distance that doesn’t stress the whale.

Professional training and equipment are needed to assess the entanglement and proceed safely with the greatest chance of success. Often, much of the fishing gear in which the whale is entangled is not visible at the surface. If well-intentioned members of the public remove the gear at the surface, it is made much more difficult to:
1. recognize that the whale is entangled and;
2. disentangle the whale even if it is relocated.

Trailing gear at the surface provides the opportunity for trained responders to attach a tag to track the whale and/or to attach floatation to maintain contact with and slow down an entangled whale. Loss of this gear can significantly reduce rescuers’ ability to save the whale.

Three Generations of Humpbacks Documented!

Three generations of Humpback Whales have now been documented!

This is such an indication of the great collaborative effort in studying the fortunate return of Humpback Whales off British Columbia’s coast, and its importance.
Calf:
Alethea Leddy was the first to document Apollo with a calf, now nicknamed Nova. Alethea’s photos from June 18th near Race Rocks even allowed us to determine that the calf is male. The calf had been lying on his back tail-lobbing whereby the pelvic area could be seen. See Aletha’s photo at the end of this blog that allowed determination of Nova’s gender. For detail on gender determination in Humpbacks, click here for our blog on the subject. 

Mother:
We know that Apollo was born in 2010 to Horizon but did not know her gender before now.

Grandmother:
We first documented Horizon in 2004 when she was already at least subadult. Apollo is her first known calf. We documented a second calf in 2013 and have not had re-sightings of this whale.

Importance:
Calves only stay with their mothers for a year. Having these solid ID photos allows us to ID them in future. Because the calves often lose a lot of the white pigmentation in their tails as they age, It is particularly helpful to also have photos showing both sides of the dorsal fin and the trailing edge of the tail. Being able to study whales as individuals allows us to have data informing everything from age of first calving (varies per population), to life expectancy, to social associations, to how the whales use the coast.

The nicknames:
Humpbacks are nicknamed for distinctive features so that it is easier to recognize them as individuals. Horizon has horizontal lines on her tail. The markings on Apollo’s tail suggest planets. And, while some of the white will likely disappear on the calf’s tail, there is a distinctive line and a moon-shaped bump that will likely stay. Thereby, Alethea suggested Nova, also keeping with the celestial theme of these 3 generations of whales.

To make the point again that it takes a dedicated community to study giants, below are the names of all those who have contributed sightings of these 3 whales (outside of our direct MERS team). This includes naturalists, captains and guest of at least 9 ecotourism companies as well as our research colleagues:
Jarret Morton, Alexandra Morton, Marilia Olio, Tasli Shaw, Mark Malleson, Gary Sutton, Jos Krynen, Amber Stroeder, Kaitlin Paquette, Johanna Ferrie, Eiko Jones, Peter Hamilton, Leif Nordman, Shea Majbroda, Michelle Mercer, Chloé Warren, Jennie Leaver, Jeff Aoki, Carmen Pen, Alison Ogilvie, Geoff Dunstan, Roger McDonell, Franz Plangger, April Macleod, Jim Borrowman, Jess Fargher, Maureen Towers, Dave Towers, Sophia Merritt, Kyle Kermode, Inge van der Wulp, Shea Majbroda, Jan Kees, Humpbacks of the Salish Sea, Keta Coastal Conservation.

How to Save a Whale (video)

“How to Save a Whale” is an essential resource on the risks of collision and entanglement. It was made possible by the Sitka Foundation. Please see below for the video and share widely.

With the fortunate increase in the number of Humpback Whales off our coast, it is essential that boaters know more about the risks of collision and entanglement (for the sake of whale AND boater safety).

Our preliminary results, conducted in collaboration with Fisheries and Oceans Canada (DFO), show that over 47% of Humpbacks in British Columbia have scarring that shows they have been entangled (>1,000 Humpbacks). This data provides an indication of how very serious the risk of entanglement is. It does not reveal how many Humpbacks have died as a result of entanglement.


For Canada’s Marine Mammal Regulations and key points on how to avoid collision, please see our page www.SeeABlowGoSlow.org. 


Summary of key points on what to do in case you find an entangled whale:

  1. With great urgency, report the entanglement with location. In British Columbia call the DFO Incident Line at  1-800-465-4336. If you do not have cell service, use VHF Channel 16 (Coast Guard).
  2. If at all possible, remain with the whale at a distance until trained help arrives or another boat takes over tracking, otherwise the chances of relocating the whale are greatly diminished
  3. Take whatever video/photos are possible but maintain a distance that doesn’t stress the whale.

Why it is so important NOT to attempt to remove any fishing gear or rope from the whale:

  1. It risks human and whale safety (has led to human death). Professional training and equipment are needed to assess the entanglement and proceed safely with the greatest chance of success.
  2.  Often, much of the fishing gear in which the whale is entangled is not visible at the surface. If members of the public put themselves at risk and remove gear at the surface, they would not help the whale because now it is more difficult to:
    – Recognize that the whale is entangled; and
    – Disentangle the whale even if it is relocated.
    Trailing gear at the surface provides the opportunity for trained responders to attach a tag to track the whale and/or to attach floatation to maintain contact with and slow down an entangled whale. Loss of this gear can significantly reduce rescuers’ ability to save the whale.
