[Guja-ryong Park, Reporter for the Korea Farmers and Fishermen Newspaper] It has been reported that the damage to scallop and oyster farms, including those in Jaran Bay, Goseong County, Gyeongnam, due to "oxygen-deficient water masses (hypoxia)" is expected to reach 4.5 billion won. Park Myeong-gyun, Deputy Governor of Gyeongnam Province, visited the scallop farms in Jaran Bay, Hail-myeon, Goseong County, on the 15th to inspect the damage caused by the oxygen-deficient water masses and to hear the opinions of the aquaculture farmers. "Oxygen-deficient water masses (hypoxia)" occur when the concentration of dissolved oxygen in seawater drops below 3.0 mg/L, caused by rising water temperatures in summer and differences in salinity due to heavy rainfall, which prevent the upper and lower layers of seawater from mixing.
