U.S. aquarium says 2nd beluga whale transferred from Marineland has died

An American aquarium says asecond beluga whale transferred there from Marineland has died.

In a statementFriday, Mystic Aquarium in Connecticut saidthefemale beluga had been in its intensive care unit and that staff and veterinarianshad beenproviding "round-the-clock medical treatment" before she died.

The cause of death won't be known until a full necropsy is carried out, it said.

"Our team provided a continuum of world-class care to this whale for many months," said Allison Tuttle, Mystic's chief zoological officer, in the statement.

"When an animal passes in the wild, it is the circle of life. When it happens at an Aquarium, with an animal you have grown to know, care for 24/7 and adore, it is devastating."

Marineland did not immediately respond to a request for comment about the whale's death.

The whale was one of five from the Niagara Falls, Ont.tourist attraction that were transported to the aquariumin May 2021 as part of a research project.

One of the five, amale whale named Havok, died in August following alengthy battle with a pre-existing gastrointestinal condition, the aquarium said at the time.

Mystic issued a statement after the most-recent deathsayingit had made changes following an inspection by the U.S. Department of Agriculturelast fall, which pointed to issues in five areas, including communication between veterinarians and animal care staff on the night of Havok's death.

Those issues also includedhandling and accommodations for animals with vision challenges, access to shade, and changes in water quality, according to the statement issued then.

Stephen Coan, CEO of Mystic, is quotedsaying that the Animal Welfare Act is meant to protect animals.

"Inspections, investigations when an animal dies, and accreditation processes are essential learning tools to advance the care and welfare of animals," he stated.

"We are constantly seeking to evolve and learn in our mission to provide the best possible care for animals."

Advocacy groups calls for investigation

Advocacy group The Animal Welfare Institute (AWI) issued a statement of its own Friday saying it was "appalled" to learn of a second death at Mystic, adding it's "disturbing" that two whales havedied less than a year after the transfer.

"These five whales were supposed to be healthy when they were imported, but it is becoming increasingly clear they were not," stated Dr. Naomi Rose, AWI's marine mammal scientist.

"These whales deserve better we demand a full government investigation into this situation. What was meant to be an uneventful import for research has become a disaster."

The transfer to Mystic happened after ananimal welfare organization sought to block the transfer of the whales in U.S. court. However,a judge declined to issue an injunction.

Both Canadian and U.S. federal governments signed off on the move.

Mystic is currently home to six other belugas, though one of them is in intensive care, the aquarium said.
