Boston Globe: A science institute wants New England college students to know if the seafood in their school cafeterias is from the region’s waters. The Gulf of Maine Research Institute is asking colleges and universities to carry its label that promises seafood products were harvested locally and sustainably. The institute offers its ‘‘responsibly harvested’’ label to vendors that can show their products are from the Gulf of Maine. So far, supermarkets, including Shaw’s and Hannaford, have been the primary vendors to carry the stamp. Wellesley College and the University of New Hampshire are the first schools to sign up, said the institute’s seafood brand manager, Kyle Foley.
