The 1m lines from pots used to catch the crustaceans are one of the two main threats to the whales, of which fewer than 340 remain
Lobster nets and pots have become such a threat to the survival of critically endangered North Atlantic right whales that the crustaceans have beenover the past decade.
Entanglement in the fishing gear used to catch lobster, crab and other species is one of the two leading threats to right whales . The whales’ migration route – from their calving grounds in Florida to feed in Canada – is littered withWhen a whale is entangled in fishing gear, the ropes can become embedded in its skin, weighing it down and leaving it unable to swim or feed properly. More than 80% of right whales have been entangled in fishing gear at least once.
Other fisheries added to the “red list” include all fishing for Jonah crab, and other trap, pot and gillnet fisheries. Gillnets are a wall of netting that hangs vertically in the water, while traps and pots also have vertical lines from the surface. Brogan said for the whale population to recover, the average number killed or injured by human activities must be fewer than one a year. “Every vertical fishing line and gillnet is a threat to the remaining whales, which face the risk of entanglement every day,” he said.
