South Korea: Research using biologging technology in the habitat of bluefin trout

The National Academy of Fisheries Science (President Dong-shik Woo) announced on the 3rd that it will investigate the habitat of bluefin trout in the West Sea by using ‘Bio-logging’ technology, which precisely investigates the ecology by attaching a small recorder to marine life. Last month, the West Sea Fisheries Research Institute of the Agricultural Institute released 10 bluefin redfish with electronic labels from the waters near Heuksan Island, Sinan-gun, Jeollanam-do. The electronic marker has a built-in sensor, so the water depth and water temperature of the sea area where the red skate moves are stored at regular intervals. From 2007 to last year, the West Sea Fisheries Research Institute of the Agricultural Institute released 1,068 trout with conventional markers to the waters near Heuksan Island to recover their resources. A total of 47 have been recaptured so far. However, the conventional markers can confirm the size and weight of the trout, but there is a limit to ...
