Currently Entangled Whales off the Coast of BC

The following will be updated as information becomes available. Last update: September 11, 2020. 

Whales known to be entangled of the coast of BC:
1. Checkmate – no longer entangled.  DFO got drone footage on September 10th that shows that Checkmate no longer is entangled. The rope that was through Checkmate’s mouth with a trap under the right pectoral fin, has fallen off. 
2. X-Ray – entangled near Campbell River, has not be found
3. Unknown whale #1 on Central Coast, has not been found, photo now available
4. Unknown whale #2  on the Central Coast, has not been found

See this link for our schedule for free webinars on our research and how to reduce threats to whales. 

There are currently 4 Humpback Whales known to be entangled off the coast of British Columbia. They may not be the only ones. These are just the whales who have been seen and reported. Note that it is the law that entanglements must be reported.

With the very fortunate increase in the number of Humpback Whales off our coast, comes this reality that there is a greater overlap between fishing gear and these giants feeding off our coast.

This page is to serve as: 
(1) The go-to for information on currently entangled whales so that there is a greater chance that they may be found so that rescue attempts can be undertaken / resumed;

(2) A resource for media and coastal British  Columbians regarding the severity / frequency of this threat and knowing what to do (and not to do).

(3) Increasing knowledge of why identifying whales as individuals is so important. Not only is it the foundation of all our research, if you want to find a whale in trouble, you need to be able to recognize the whale and know where it most often can be found.

How big a threat is entanglement to Humpbacks?
The preliminary results of our research, conducted in collaboration with DFO, shows that approximately half the Humpbacks off the coast of British Columbia have scarring that shows they have been entangled. This provides an indication of how much the following are needed: boater education, resources for disentanglement, and understanding of how to reduce the threat. But please know, that entangled whales so often escape detection and most dead whales sink.

How you can help:
You can help by being alert for the possibility of entangled whales and educating yourself about what to do with the information we have provided at This includes insight into how disentanglement are conducted and why it is not only extraordinarily dangerous to attempt disentanglement but were one to do so, you might be dooming the whale by removing the ability to see the the whale is entangled (because what is visible at the surface has been removed) and by removing the ability to attach a geo-tag to the gear so that the whale can be  found and the expertise and equipment can be used to attempt rescue.

Know that the whales are most often not in immediately danger of dying from entanglement. It is the longterm impacts of infection and not being able to feed and/or move properly that will kill them.

The biggest limiting factor in rescuing the whales is finding them back as the realities of the following four whales will make very clear. But know too we can never detect or find back all the entangled whales off our coast. The problem of entanglement must ultimately be dealt with at the source for the sake of the whales, the fishing community re. impacts due to lost gear; and for the sake of fisheries trade with the United States (see end fo the page for the court ruling in that regard). .

Entangled Humpback #1

Checkmate was documented as entangled on July 25th due to the vigilance of a member of the whale watching community around Campbell River. It was immediately called in to the Incident Reporting Line at 1-800-465-4336. Expertise was dispatched to Campbell River with Straitwatch maintaining watch on the whale.

It is known that a member of the public removed rope at the surface. This was a terrible mistake, and also illegal. The gear at the surface would have allowed ease of recognizing this whale as entangled. It would have allowed for a tracking tag to be attached so that the whale could be relocated. And, it would have allowed far better possibility of being able to remove the entangling gear below the surface. The prognosis for Checkmate is very poor. Rope from a trap is through Checkmate’s mouth, trailing over the right pectoral fin. 

Because there is nothing at the surface, it was also not possible to attach a tracking tag to the rope so that Checkmate could be found whereby disentanglement attempts by DFO could continue.

Checkmate was relocated by Straitwatch on the afternoon of August 19th in the Campbell River area and again on the late afternoon August 22nd. DFO got drone footage on September 10th that shows that Checkmate is no longer entangled. So fortuitously, the rope that was through Checkmate’s mouth with a trap under the right pectoral fin, has fallen off. 

Entangled Humpback #2

X-Ray was last seen near Kelsey Bay with an adult whale, Slits on July 26. May no longer be traveling together. DFO has been able to remove some of the entangling gear. Whale needs to be found back  in the hopes of removing the remaining gear. 

Rope from a trap is through X-Ray’s mouth and trailing  under the right pectoral fin. 

Entangled Humpback #3

The photo below was taken on the late afternoon of July 29th near Ashdown Island. This Humpback has netting over its head which is unlikely to be evident at the surface. Colleague Humpback researchers have also reviewed this photo and we do not know this individual. This suggests the whale is more often in an area where we do not get ID photos. The whale has not been relocated since July 29th. It is know that there were multiple interactions between Humpbacks and netting during this seine fishery. These entanglements are of course also a problem for the human fishers striving to make their living. 

It is the law that entanglements must be reported. Exact language from Canada’s Marine Mammal Regulations is included below.  Click to enlarge. 

Entangled Humpback #4 

There are currently no photos known to us that would allow confirmation of the identities of this whales. The entanglement was not reported until well after it happened whereby it will be far more challenging to find the whale. If there are no photos to aid the identification of the whales, this further confounds chances of finding them, especially if there is not evidence of entanglement at the surface.

With regard to entanglement of whales impacting the economics of fisheries trade with the USA:

The Marine Mammal Import Provisions Rule, went into effect on January 1st, 2017 (with a 5-year grace period). To comply with this regulation by January 1st, 2022, countries importing seafood into the United States must be able to prove their fisheries monitor and limit marine mammal bycatch with the same standards as U.S. fisheries are required to do under the Marine Mammal Protection Act.
