The Amia calva bowfin fish has been recently introduced to the Connecticut River drainage of Massachusetts. In the 1980âs, bowfin fish was found in the Lower Mill Pond and the Nashawannuck Pond in Easthampton, Massachusetts.Most scientists agree that some of these bowfin fishes later migrated down the Mahan River until they reached the Oxbow in the Connecticut River.ike many other fish species that live in low-oxygen waters, the bowfin fish have adapted to these conditions and can breathe oxygen directly from the air by swimming up to the surface. Unlike land living animals, the bowfin fish gulps air into the swim bladder.
