A new analysis of New England’s shrimp population doesn’t bode well for the future of the long-shuttered fishery for the crustaceans. The Maine-based shrimp fishery has been shut down since 2013 because of concerns such as warming ocean temperatures and poor survival of young. Scientists working with the Atlantic States Marine Fisheries Commission are assessing the shrimp stock, and so far it looks like little has changed. Results of the stock assessment “look fairly similar to what we’ve seen in previous years,” said Megan Ware, a fishery management plan coordinator with the Atlantic States. That means reopening the fishery any time soon could be a tough sell when regulators meet to discuss and vote on the subject this fall. The shrimp were a popular winter seafood item in New England and around the country before regulators shuttered the fishery. Fishermen sought them with trawler boats and traps in Maine, New Hampshire and Massachusetts, sometimes catching more than 10 million pounds in a single year.
