If Properly Managed, Atlantic Cod Stocks Could Rebound: Study

New research on Atlantic cod, led by scientists at Rutgers University, concludes that if properly managed, stocks of the popular white fish may rebound, now that commercial fishing pressure has been reduced. The study, published in the Philosophical Transactions of the Royal Society B: Biological Sciences, offers the first genomic evidence that Atlantic cod evolved new traits over only decades during a period of overfishing – evolutionary changes that scientists formerly believed could take millions of years. “The discovery was made possible by new technology that allowed us to extract and read the genetic code of cod, some caught more than 110 years ago, as well as new analytical techniques that detect subtle changes in that genetic code,” said Malin Pinsky, senior author on the stud...

Bering Sea Crabbers Partner With Alaska, Feds to Study Red King Crab

Harvesters in the Bristol Bay red king crab fishery are partnering with federal and state agencies to collect critical winter data in a month-long project that was slated to start in March to help inform management decisions. The research goal is to collect data sought by the North Pacific Fishery Management Council to help the council decide what actions might improve those stocks to a level to allow for the multi-million-dollar fishery to resume. The study’s lead, Mike Litzow of NOAA Fisheries’ Alaska Fisheries Science Center, said the collaborative effort offered an exciting chance to study these crab stocks in winter. “That’s when people really interact with the stock — the Bristol Bay red king crab fishery and many other fisheries that potentially interact with crab take place in...

Study Tracks Shifting Identities of Global Fishing Fleet

A new international research study has tracked 35,000 commercial fishing and support vessels, identifying their changing of country registration and also identified hotspots of potential unauthorized fishing and activity of foreign owned vessels. Changing the country of origin is a practice also known as “reflagging.” The study, “Tracking Elusive and Shifting Identities of the Global Fishing Fleet,” was published Jan. 18 in Science Advances, the open access multidisciplinary journal of the American Association for the Advancement of Science. Participants in the project were researchers from Global Fishing Watch, the Maine Geospatial Ecology lab at Duke University and the Stockholm Resilience Centre. The study found that close to 20% of high seas fishing is done by vessels that are eit...
