April 3, 2017 — New England’s iconic cod fishery has hit an all-time low. Scientists point the finger at a combination of fishing and climate change. Many fishermen reject that assessment and blame their woes on regulators. A new documentary film, Sacred Cod, tells the story of two populations in crisis – the cod, and the fishermen who’ve built a way of life around them.
Cod fishing is what brought the first Europeans to New England, and the commercial fishery is the oldest in the nation. Hundreds of years of fishing pressure has brought cod populations in southern New England and the Gulf of Maine to record low levels. Federal fishery biologists have estimated that the reproductively active population is just 3-4 percent of what would be needed for a healthy, sustainable fishery.
That hasn’t improved in the past few years, despite fishing restrictions that amount to a virtual closure of the fishery. Scientists say climate change is a likely culprit. Rising water temperatures affect reproductive success, reducing the number of eggs a female produces and also reducing survival of young codfish. Scientists are also seeing changes in the base of the food chain that may be linked to climate change.
Many fishermen reject this assessment, though, and say fishing restrictions are unnecessary. They contend that there are plenty of cod to be caught, if you just know where to look.
