Author	Research Cooperation Division	Date	2025-04-21	Read	688
Annual Scapharca subcrenata yields: 8,995 tons in 2019, 6,177 tons in 2022, and 4,456 tons in 2024 -2.1℃ in 2024 compared to 2010, and was 2.0℃-2.1℃ higher in 2024 compared to the 15-year average bottom water temperature. The Chemical Oxygen Demand (COD) also increased 1.6-2.5 fold in 2024 compared to 2010. *COD helps determine the level of pollution in water by indicating the amount of organic and inorganic substances present. Higher COD indicates greater pollution of severe eutrophication and organic accumulation.
