Legend has it that cod, haddock, perch and other North Atlantic fish were once so plentiful off the coast of New England that fisherman could almost literally scoop them from the water. Today, that bounty is almost gone, due mainly to many decades of severe-over-fishing. Innovative research into the area fish decline is helping scientists and fishermen understand what makes the marine ecosystem and how fish populations might be restored – for humans and the untold numbers of other living things that depend on them.
