The Bureau of Fisheries and Aquatic Resources (BFAR) on Thursday warned of another possible fish kill after their monitoring revealed “poor water quality” believed caused by the ashfall from the phreatic eruption of Mt. Bulusan on June 5. Nonie Enolva, spokesperson for the BFAR Bicol, said laboratory results of water tests that the agency conducted showed high levels of ammonia and hydrogen sulfide, which meant “water quality is not suitable for aquaculture purposes.” Water samples were taken from a tilapia pond at Sitio Caladgao in Barangay Buraburan, Juban town, and six stations in Sorsogon Bay.
