Deaths of two beluga whales at Vancouver Aquarium remains a mystery
All possible explanations — from food sickness to intentional poisoning — are being investigated for the deaths of two of the Vancouver Aquarium's beluga whales after examinations failed to pinpoint why they died, an official said Monday.
Aquarium CEO John Nightingale described the deaths of the two animals in such quick succession as unprecedented, not only at the aquarium, which has operated for six decades, but also at other such institutions.
"I don't have to tell you it's perplexing," Nightingale told a room of reporters, three days after Aurora the beluga died.
Fewer than two weeks ago, Aurora was put under round-the-clock supervision and veterinary care after she began to exhibit the same symptoms that preceded the recent death of her 21-year-old calf, Qila. Aurora died on Friday, nine days after Qila.
"The pledge from myself, from our board, from our entire staff and volunteers, is: we're going to get to the bottom of it," Nightingale added. "The guiding principle is: absolutely no stone unturned."
None of the aquarium's five other belugas housed at facilities across the United States will return to Vancouver, nor will construction begin on the tank enlargement, until the belugas' deaths are understood, Nightingale said.
"We will not make any decisions about going forward until we know what happened," he said. "To do otherwise would be irresponsible."
Martin Haulena, chief veterinarian at the aquarium, said the similarities in behaviour and symptoms suggest Qila and Aurora's illnesses were linked. The most likely culprit is either a virus or a toxin, and tissue samples have been sent to various universities for analysis, he added.
"This does not happen on my watch," Haulena said. "This is not what I do.
"I will not rest until we find some answers. That's a promise. And neither will anyone else around here. We loved those whales."
Sara Dubois of the British Columbia SPCA extended condolences to the aquarium but emphasized her society's opposition to keeping whales in artificial enclosures.
"Any time you care for an animal for so long you can imagine how heartbreaking it is to lose them, especially in such an unexpected way," Dubois said. "At the same time, I think it's a really good time to take a reflection on what the future will be."
This is a real leadership opportunity for the aquarium to envision the future of marine facilities and to invest in the idea of whale sanctuaries, she said.
In 2010, park commissioners rejected a motion for a plebiscite asking if the whale and dolphin exhibits should be phased out at the aquarium. But the deaths of the belugas has renewed a call from critics.
