Last of lingering North Atlantic right whales heading out of Bay of Fundy

HALIFAX (CP) – Dozens of rare North Atlantic right whales that were lingering in the Bay of Fundy are finally heading out of the area, amid fears that some could become ensnared in dangerous fishing lines as they move south.
Officials said Friday that there were as few as three of the massive mammals in the bay, after more than 40 of them had delayed their departure by six weeks because of an abundance of plankton.
Jerry Conway of the Department of Fisheries said the endangered whales were trekking south on their annual migration and were spotted in the Gulf of Maine as they venture toward waters off Georgia and Florida.
But, he said he’s received unsubstantiated reports of whales becoming entangled in lengths of lobster line that create a hazard for the slow-moving creatures as they pass through the bay. Conway said fishermen have found some of their gear is missing, raising the possibility that it may be wrapped around some whales.
“There may be two or three whales entangled in gear,” he said. “It has been suggested that there is gear missing that may be showing up in the near future on whales.”
One whale was apparently freed from lobster gear by a fisherman who spotted it and managed to disentangle it. The move came after the start of the lobster fishery was delayed slightly by the whales’ presence in the bay.

Lobster fishermen agreed not to set traps within two kilometres of a whale in a bid to prevent entanglements, while the Fisheries Department conducted aerial surveillance flights to track their movements.
Officials and conservation groups say the whale’s eventual departure caps a bleak season that saw the loss of two females and the deaths of a calf and adult that were hit by ships in the summer feeding grounds.
Both females were killed in Canadian waters, with one found to have 17 vertebrae in her back crushed in a ship collision.
“The loss of even one female right whale could have a significant impact on the ability of the species to survive,” said Conway. “The loss of two is a really serious impact.”
Conway said the two whales could have produced in excess of 20 calves over their lifetimes – a vital contribution to a population that has dwindled to about 320 worldwide after years of being slaughtered, dying in gear or being struck by ships.
About 19 right whales were born this year, but one calf was killed and a pregnant female died in U.S. waters.
Scientists and ecologists are hoping to reduce the risk of ship strikes by pressing the International Maritime Organization to make the Roseway Basin an area to be avoided by large vessels.
Whales migrate to the basin, a diverse ecosystem rich in marine life off the southwest coast of Nova Scotia, every year to feed on plankton and other food sources.
Lori Murrison of the Grand Manan Whale and Seaboard Research Station said Transport Canada has approved the initiative to issue an advisory to seafarers and is optimistic the international group will approve it, possibly next year.
“There can be a substantial number of right whales in that area in the summer time,” she said from Grand Manan, N.B. “So it is important to have that designated.”
If accepted, vessels would be asked to steer clear of the area from June through September while the whales are in the area, but Conway said the measure would be voluntary not binding.
The IMO altered shipping lanes in the Bay of Fundy in 2003 to create a buffer between passing vessels and right whales in the area.
Boat strikes and entanglement in fishing gear pose the greatest risks to the right whales.
