    Phosphorus as a driver of nitrogen limitation and sustained eutrophic conditions in Bolinao and Anda, Philippines, a mariculture-impacted tropical coastal area
    Ferrera, Charissa M.; Watanabe, Atsushi; Miyajima, Toshihiro; San Diego-McGlone, Maria Lourdes; Morimoto, Naoko; Umezawa, Yu; Herrera, Eugene; Tsuchiya, Takumi; Yoshikai, Masaya; Nadaoka, Kazuo (Elsevier, 2016)
    The dynamics of nitrogen (N) and phosphorus (P) was studied in mariculture areas around Bolinao and Anda, Philippines to examine its possible link to recurring algal blooms, hypoxia and fish kills. They occur despite regulation on number of fish farm structures in Bolinao to improve water quality after 2002, following a massive fish kill in the area. Based on spatiotemporal surveys, coastal waters remained eutrophic a decade after imposing regulation, primarily due to decomposition of uneaten and undigested feeds, and fish excretions. Relative to Redfield ratio (16), these materials are enriched in P, resulting in low N/P ratios (~ 6.6) of regenerated nutrients. Dissolved inorganic P (DIP) in the water reached 4 μM during the dry season, likely exacerbated by increase in fish farm structures in Anda. DIP enrichment created an N-limited condition that is highly susceptible to sporadic algal blooms whenever N is supplied from freshwater during the wet season.

    Who killed the milkfish?
    Cardinoza, Gabriel (Philippine Daily Inquirer, Inc., 2011-06-08)
    They're stubborn. These are the words of Nestor Domenden, regional director of the Bureau of Fisheries and Aquatic Resources (BFAR) when asked why fishkills have been a recurring nightmare in Bolinao and Anda towns in western Pangasinan in the last 10 years. “They (milkfish growers) know where their fishing structures should be built, but they continued to disregard it,” Domenden says. A report from the office of the provincial agriculturist in Lingayen shows that 72 of the 75 fishkill-hit cages were built in the waters off Catubig Point in Barangay Tara up to Barangay Culang in Bolinao, while the rest, mostly bamboo pens, dotted the fishing area from Barangay Mal-ong to Barangay Awag and across the Kakiputan Channel to the island village of Siapar in Anda.

    BFAR assures enough supply of bangus amid Pangasinan fishkill
    (Manila Bulletin Publishing Corporation, 2018-06-08)
    The Bureau of Fisheries and Aquatic Resources (BFAR) in the Ilocos region has assured that there is an ample supply of milkfish (bangus) for the region and other regions, despite the recent fishkill in the towns of Anda and Bolinao. BFAR Regional Director Nestor Domenden, in an interview during a fisheries forum on Wednesday, revealed that less than 1 percent of the region's total production for the year was lost due the fishkill. Domenden said the region is self-sufficient in bangus production and can continue supplying the needs of other areas, including Metro Manila, as the region is 127 percent sufficiency.
