    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.

    El Niño seen dampening seaweed, crab production
    Conserva, Louine Hope (BusinessWorld Publishing Corporation, 2015-10-06)
    Production of seaweed and mud crabs is expected to decrease due to the higher temperatures brought about by the prevailing El Niño. Production of seaweed and mud crabs is expected to decrease due to the higher temperatures brought about by the prevailing El Niño. Officials of the Southeast Asian Fisheries Development Center (SEAFDEC) said both seaweed and mud crabs cannot thrive in water temperatures higher than 32 degrees centigrade. “Normal temperature is about 30 degrees centigrade, but right now it has increased to 32. Longer exposure to higher temperature would be damaging (for seaweed),” said Maria Rovilla J. Luhan, SEAFDEC associate scientist and head of the Farming Systems and Ecology Section.
