In Newfoundland, where tens of thousands of people lost their jobs after the Canadian government banned the fishing of cod in 1992, there’s something new in the salty air of many of the island’s old, neglected fishing towns. As the iconic cod population finally rebounds after nearly a quarter century of historic decline, there’s a sense of hope, a promise of better days to come.

Craig Purchase, associate professor of biology at Memorial University of Newfoundland, uses a net to gather capelin for his research at Middle Cove Beach in Newfoundland. The silver fish spawning on the shore is the primary food source for cod.
