OCEAN BEACH, Australia: Almost 200 whales have perished at an exposed, surf-swept beach on the rugged west coast of Tasmania, where Australian rescuers were only able to save a few dozen survivors Thursday (Sep 22).
After an arduous, day-long effort in difficult conditions, state wildlife services said just 32 of the 226 beached long-finned pilot whales were strong enough to be rescued.
“We’ve been refloating those whales that have been deemed suitable for release back to sea,” Sam Thalmann, a marine biologist, told AFP.
“Every whale that has been released has been tagged,” he said. “There may be a few that re-strand unfortunately, but we expect that by far the majority will head out to sea.”
Locals had covered some of the mammals with blankets and doused them with buckets of seawater to keep them alive until more help arrived.
But many of the whales were too far gone.
By nightfall, scores of the glossy black whales were strewn along Ocean Beach, their carcasses pockmarking the waterline where the frigid southern ocean meets the sand.
“Unfortunately we do have a high mortality rate on this particular stranding,” said state wildlife operations manager Brendon Clark.
“The environmental conditions, the surf out there on the exposed west coast, Ocean Beach, is certainly taking its toll on the animals.”
Efforts will now turn to the considerable task of disposing of the whale bodies safely.
If left in shallow waters or on the beach, they could attract sharks and can carry disease.
“There is a lot more work to be done with the carcass disposal,” said Thalmann, who added that “valuable biological samples” would need to be collected from the animals.
Those could help scientists understand how and why “the animals strand at this location”.
“There (are) certainly some local characteristics that lead to this spot being repeatedly a site for mass whale stranding.”
Two years ago, Macquarie Harbour was the scene of the country’s largest-ever mass stranding, involving almost 500 pilot whales.
More than 300 pilot whales died during that event, despite the efforts of dozens of volunteers who toiled for days in Tasmania’s freezing waters to free them.
Clark said the conditions of the latest stranding were tougher for the whales than two years ago when the animals were in “much more sheltered waters”.
