    Bureau of Fisheries and Aquatic Resources (BFAR) Region 5, meanwhile, reported an initial 20 metric tons of tilapia valued at P2.1 million were lost. BFAR-5’s Regional Fisheries Laboratory conducted water sampling in six villages — Iraya, Ibayugan, Tambo, Cabatuan, Salvacion and Sta. Elena. Results showed low dissolved oxygen (DO), ranging from 0.18 to 4.37PPM, and very high ammonia (ranging from 7.58 to 10,679 mg/L) content in Lake Buhi. Normal and tolerable ranges of DO are below 5PPM and ammonia at only 0.050 mg/L or lower.

    Simeon, Louise Maureen (Philippine Star Printing Co., Inc., 2019-02-09)
    Fish cage operators can now resume feeding their fish stocks in Taal Lake after tests showed improvements in the quality of water. Agriculture Secretary William Dar said tests conducted by the Bureau of Fisheries and Aquatic Resources (BFAR) from Jan. 14 to 30 revealed that the level of dissolved oxygen in Taal Lake, which is essential to fish growth and survival, had already improved. BFAR Calabarzon director Sammy Malvas said Taal water quality tests also showed that the sulfide level is within normal.
