"Oxygen-deficient water masses" 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 concentration due to heavy rains, which prevent the upper and lower layers of seawater from mixing. This phenomenon leads to the death of shellfish and other marine life, causing fishery disasters. This year, it was first observed in Jinhae Bay on June 11. From September 3, reports of damage to scallops, oysters, and other shellfish due to oxygen-deficient water masses began in Changwon City ...
