MANILA, Philippines - Oxygen depletion in the waters near the Manila Yacht Club may have caused a fish kill yesterday morning, according to the Bureau of Fisheries and Acquatic Resources (BFAR).
Dozens of dead mullet fish were seen floating in Manila Bay near the breakwater at dawn, the Philippine Coast Guard (PCG) said.
Dissolved oxygen levels from three sampling stations were at 1.2, “way below the normal oxygen level of five (and above)… to be able to sustain marine life,” according to the BFAR’s initial report.
“Apparently, the water quality in the Manila Yacht Club breakwater is polluted due to stagnation, hence the cause of the fish kill,” the PCG added.
The PCG said there had been no chemical or oil spills that could cause the fish kill.
