Gulf Kingfish (IMAGE) Terry Collins Assoc Caption Found through DNA left behind off the coast New Jersey shore, the perch-like Gulf kingfish has never before been recorded north of Chesapeake Bay, Virginia, about 250 miles (400 km) to the south. With changes in the oceans owing to climate, chemical pollution, debris, noise, night-time illumination, and other factors, "this study further establishes aquatic environmental DNA (eDNA) as an innovative, inexpensive, low-impact way to monitor marine life migrations, changing ranges, diversity and distribution," says Jesse Ausubel Credit SEFSC Pascagoula Laboratory; Collection of Brandi Noble, NOAA/NMFS/SEFSC Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
