One of the two critical areas where New England fishermen search for cod may be in even worse shape than suspected. The Northeast Fisheries Science Center says research boats caught less cod this past spring in 2015 than in all but one spring season dating back to 1968. (AP Photo/Robert F. Bukaty, File)
