July 26, 2021 — This month, two right whales in the Gulf of St Lawrence were found entangled in fishing gear. One, a female, was first spotted entangled off Cape Cod last year, but rescuers were not able to fully free her; the other, a male, is believed to have become entangled in the Gulf.
Hunted to near extinction before a partial whaling ban in 1935, North Atlantic right whales are once more critically endangered, with only 356 left. The main threat remains human contact: entanglement in fishing gear, and ship strikes. Fatal encounters, caused in part by the whales’ migratory shift into Canada’s snow crab grounds, have soared: more than a tenth of the population died or were seriously injured between 2017 and 2021, mostly in Canada and New England.
One of the threats they face is from the growing crab and lobster fisheries. The whales migrate from their calving grounds in Florida to feed in Canada – putting them on a collision course with the pots and traps.
“We’re talking millions of lines, placed in the water every year,” says Kate O’Connell, a marine wildlife consultant for the Animal Welfare Institute. “These animals are running the gauntlet – and it’s getting harder and harder for them to survive.”
When a whale gets entangled, ropes from buoys on the surface to the seabed traps can become embedded in its skin, weighing it down and leaving it unable to swim or feed properly, leading to a “really traumatising death”, O’Connell says.
But what makes it even more concerning to conservationists is that some of the fisheries they say threaten the right whale were certified as “sustainable” by the world’s largest fisheries certification programme: the Marine Stewardship Council.
The MSC, which grants the right to use its well-known “blue tick” label on products, has grown from 315 certified fisheries in 2017 to 421, representing 14% of all global fish landings. In the last year its labelled products were worth $12bn (£9.5bn). In the absence of governments looking after our oceans, “the MSC is definitely the best we’ve got” in terms of consumer labels, according to Ruth Westcott of the environmental alliance Sustain.
