The Vancouver Aquarium has concluded its five-month investigation into the sudden passing of two beluga whales, Qila and Aurora, in November 2016. The comprehensive investigation involved dozens of veterinary pathologists, toxicologists, genome specialists, medical doctors, and field research scientists, among others.

Results of the investigation concluded that the cause of death in both animals was a toxin. Extensive testing was unable to identify the exact substance involved, which is not uncommon due to the very limited time a toxin is traceable in the bloodstream. The investigation also determined that the toxin was likely introduced by food, water, or through human interference.

“The loss of Qila and Aurora was devastating. They were beloved members of our family and the community for more than two decades. Their loss is felt profoundly by our staff, members, supporters, and the public,” said Dr. Martin Haulena, Head Veterinarian at Vancouver Aquarium. “The investigation has helped us understand what happened and, importantly, how we can best ensure the safety and welfare of marine mammals in our care.”

Vancouver Aquarium is currently home to a false killer whale, a Pacific white-sided dolphin, and a harbour porpoise – all receiving long-term care as part of the Aquarium’s Marine Mammal Rescue Centre Program.

Since the passing of Qila and Aurora, the Aquarium has taken several measures to test, evaluate, and reduce risks in the Arctic habitat.

To reduce the risk of a toxin being introduced by food / ingestion:

  • An enhanced food-screening process, which far exceeds best practice standards
  • All vegetation adjacent to the habitat that could be considered problematic has been, or will be removed .

To reduce the risk of a toxin being introduced by water:

  • Mechanical water treatments systems are being overhauled and replaced as a precaution in all habitats that house whales, dolphins, and porpoises
  • New, real-time testing and monitoring of incoming and circulating water within the habitat and mechanical systems has been implemented.

To reduce the risk of a toxin being introduced through human interference:

  • Significant security updates have been deployed to monitor perimeter access and reduce potential threats of human interference

“We deeply appreciate the assistance of world-class experts during the investigation process, the outpouring of support from members and the local community, as well as the unwavering dedication of our staff and volunteers,” said Dr. Haulena. “The conclusion of the investigation helps bring closure to an extremely difficult situation.”

    I am so deeply sorry for the loss of two beautiful beluga whales. I was devastated to learn what happened and now to learn that a mysterious toxin took their lives. In honour of the whales, never stop doing your incredibly important marine research. At every level of your work, you are world class marine biologists, scientists, technicians, veterinarians, and managers of a highly valued facility and your volunteers and assistants are brilliant. Thank you for keeping us, the public, informed and for doing everything you can so that this tragedy can never happen again. We will always cherish the memory of Qila and Aurora.
