Menhaden were back in Cuttyhunk harbor this summer, and that was good news to Capt. Bruce Borges. Pogies, as they are called, make great bait for catching striped bass. As a lobsterman, Captain Borges, 74, hasn’t seen much good news along the waterfront in recent years. There are fish out there but it’s a different story for lobsters, and that has made this summer especially challenging for Mr. Borges, who calls himself the last lobsterman on Cuttyhunk.
