A mass fish die-off occurred in the waters of Laguna de Bay near Pililla town in Rizal province on July 21, 2026. The Philippine Coast Guard (PCG), in collaboration with the Bureau of Fisheries and Aquatic Resources (BFAR), conducted an on-site investigation and identified potential causes such as algal blooms, high water temperatures, and poor water circulation. These factors may have led to low dissolved oxygen levels, harming aquatic life. The affected area included bighead carp and milkfish, and local fishermen reported visible changes in the water's condition. The PCG informed the Laguna Lake Development Authority (LLDA) about the incident for further monitoring and action.
