Some American businesses have stopped selling lobster because of concerns that fishing methods could harm endangered whales. Several food companies announced they had removed lobster offerings to the public. The removals came after a conservation group said it had added the American and Canadian lobster fisheries to its “red list.” It is a list of species to avoid when buying seafood. The organization that makes the list is called Seafood Watch. It is based at the Monterey Bay Aquarium in northern California. Seafood Watch said in a new report that the fishing industry is a danger to North Atlantic right whales. The whales can suffer injury or death when they become trapped in equipment that connects lobster traps to the ocean floor. The organization’s report said that “current management measures do not go far enough” to prevent such risks and to support efforts to save the whale species. Thousands of businesses use Seafood Watch's guidelines to make buying decisions. Many have already promised to avoid any products that appear on the red list. A spokesperson for Blue Apron, a New York-based food seller, said the company had already stopped offering a seasonal lobster box before the report came out. The company said all the seafood it currently uses follows Seafood Watch's guidelines.
