Experts seek clues in death of 8th whale
MISCOU ISLAND, N.B.• Marine mammal experts began carving up the remains of another endangered North Atlantic right whale on Friday in a bid to determine what caused the death of the latest whale to be found floating in the Gulf of St. Lawrence.
Matthew Hardy of the Fisheries Department said around 30 people were assisting in the necropsy — or animal autopsy — being conducted near a lighthouse on the northern tip of Miscou Island, N.B. The animal is the eighth North Atlantic right whale to have died in the Gulf over the last six weeks.
Hardy said the whale was first spotted Wednesday afternoon east of Shippigan, N.B., while another right whale was found entangled in fishing gear in the in the Gulf.
“We’re responding to this in a very ... proactive manner to try and get to the bottom of this,” Hardy said.
A full-sized excavator was on site, peeling back layers of blubber so scientists can look at the animal’s internal organs. Hardy described the smell as “unforgettable,” but said the 14-metre carcass is in fresher condition than the rotting remains that were examined in the previous five necropsies.
The Fisheries Department closed a snow crab fishing area encompassing most of the southern Gulf to protect right whales from the dangers posed by fishing gear.
“This is sort of a first for the department, to make an emergency closure like this,” Hardy said. “It’s that serious when we have eight confirmed mortalities of a population of about 500 (right whales).”
Prime Minister Justin Trudeau said he has asked Fisheries to keep a close watch on the issue.
Sean Brilliant of the Canadian Wildlife Federation applauded the effort, but said the government will have to go further.
“It’s never too little, too late,” Brilliant said. “We need to look after this whale. It is a part of who we are (as) Canadians.”
Brilliant said the North Atlantic right whale was hunted to near extinction before the practice was banned in the 1930s. Today, he said, other kinds of human activity in the ocean threaten the species’ survival.
Last week, the wildlife co-operative said a necropsy performed in the Magdalen Islands on one of the dead right whales in the Gulf of St. Lawrence showed it had marks of blunt trauma, suggesting it may have collided with a vessel.
Tests performed earlier on two other North Atlantic right whales in Prince Edward Island also showed signs of blunt trauma. Another died as a result of an entanglement in fishing line.
Scott Kraus, vice-president and senior science adviser at the Anderson Cabot Center for Ocean Life at the New England Aquarium in Boston, said another death may be imminent after an entangled right whale was spotted in the Gulf.
Disentanglements of right whales were recently put on hold by Ottawa following the death of a whale rescuer in New Brunswick.
Kraus said Canadian fisheries officials are trying to tag the entangled animal with a satellite tracker so they can monitor its movements, but absent human intervention, the whale may not be able to free itself. “(Its) prospects are probably not that good,” said Kraus.
He said the vast majority of North Atlantic right whales have at some point experienced an entanglement.
