November 7, 2019 — The probable cause of the death of a North Atlantic right whale found in September off Long Island is entanglement in fishing gear, according to the National Oceanic and Atmospheric Administration.
The 40-year-old male whale, known as No. 1226 and named “Snake Eyes,” died after being seen alive in July and August in the Gulf of St. Lawrence. In September, researchers performed a necropsy at Jones Beach State Park to determine the cause of death.
Critically endangered right whales — which spend late winter and early spring in Cape Cod Bay and nearby waters — are experiencing what is called an unusual mortality event along the Atlantic coast, given the high number of deaths since 2017, which currently stand at 30, according to NOAA.
There are currently about 400 right whales remaining.
“His death is testament to a couple of important issues,” said Regina Asmutis-Silvia, who directs Whale and Dolphin Conservation in Plymouth. First, the habitats of right whales have shifted both in the United States and Canada and government managers who protect the animals must also shift the areas being managed, Asmutis-Silvia said. Second, fixed gear fisheries, such as commercial lobstering, are an unintentional but lethal threat to the species’ survival, and the faster gear modifications can be implemented the more likely it is that the species and fisheries can both thrive, she said.
