CAN - New ropeless fishing technology, which can help save whales, tested off Newfoundland
ST. JOHN’S, Newfoundland - A test deployment of ropeless fishing gear last month off the coast of Newfoundland brought to life a more than four-decades-old dream of biologist Michael Moore — and in a way, the test brought those dreams home.
Moore is the director of the Marine Mammal Center at the U.S.-based Woods Hole Oceanographic Institution, and he said his career has been deeply influenced by the late Newfoundland marine biologist Jon Lien. Lien is known for developing techniques to free whales caught in fishing ropes, and he released hundreds of the animals over the course of his career.
Moore said Lien first told him about the whale-saving potential of ropeless fishing gear four decades ago during a road trip across Newfoundland.
“Forty-three years later, his hope and his prophecy is coming true,” Moore said in a recent interview about Lien. “It’s very special.”
Ropeless fishing technology is still in its infancy, but there are high hopes among scientists and fishers that it will result in fewer whales getting trapped in fishing ropes and help fishers. Efforts to deploy the new fishing methods are focused on the endangered North Atlantic right whale, of which there are only about 336 remaining in the world.

Moore authored a study in 2020 suggesting 85 per cent of right whale deaths between 2010 and 2015 were caused by entanglements with fishing gear. Scientists like Moore hope the widespread adoption of ropeless gear will curb those entanglements and allow the species to recover.
Last month, acoustic technology developed by Jasco Applied Sciences was outfitted on crab and lobster traps that were deployed off the coast of Harbour Breton, N.L., and just outside the St. John’s, N.L., harbour. The test run was launched through a partnership between Jasco, the Washington-based non-profit Sea Mammal Education Learning Technology Society, and the commercial fishing arm of the Miawpukek First Nation in Newfoundland.
Fishers can release the traps into the water and find them again through an acoustic signal, Jasco engineering manager John Moloney said in an interview Tuesday. The traps are equipped with inflatable bladders that fishers can trigger when it’s time to bring them up to the surface.
