The fish kill in Manila Bay this week might have been due to an “oceanographic phenomenon called the upwelling or overturn caused by the depletion of dissolved oxygen among fish,” the Department of Agriculture’s Bureau of Fisheries and Aquatic Resources (DA-BFAR) said on Saturday. The DA-BFAR statement comes after an estimated 10 kilograms of fish turned up dead in the Baseco area on Sept. 15, 2020, which environmental groups blamed on the “white sand” dolomite nourishment project by the Department of Environment and Natural Resources (DENR) as part of the Manila Bay rehabilitation.
