Atlanta Aquarium Euthanizes Beloved Beluga Whale

ATLANTA — Gasper, one of the Georgia Aquarium's five prized beluga whales, was euthanized yesterday morning after months of declining health, officials said.

Before being brought to Atlanta, Gasper and his tank mate Nico had been housed in substandard conditions in a tank located beneath a roller coaster at an amusement park in Mexico City.

The 17-year-old Gasper had been ill before arriving at the aquarium in October 2005. His health deteriorated further over the past few weeks. That led the aquarium's medical team to make "the difficult decision to humanely euthanize the animal," aquarium officials said in a statement.

Gasper's decline was believed to be the result of his weakened immune system, the aquarium said.

Gasper was in poor health with numerous skin lesions when the new owners of the amusement park agreed to move the whales to Atlanta. Aquarium veterinarians later discovered Gasper had the potentially deadly bone disease osteomyelitis, and he was taken off exhibit for treatment in April.
