- Phosphorus as a driver of nitrogen limitation and sustained eutrophic conditions in Bolinao and Anda, Philippines, a mariculture-impacted tropical coastal areaFerrera, 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.
- Lake Sebu fish kill destroys ₱20M worth of tilapiaSarmiento, Bong S. (Philippine Daily Inquirer, Inc., 2021-01-13)At least 1,000 fish cages containing about 200,000 kilograms of tilapia were ravaged by the latest fish kill in Lake Sebu town, South Cotabato province, last week, an official said on Monday. Lake Sebu Mayor Floro Gandam said at least 250 tilapia growers would get aid from the local government to recover their losses estimated at P20 million.But officials who joined an emergency meeting which Gandam convened on Monday did not think the damage was extensive enough to place the town under a state of calamity. Christopher Ofong, the municipal information officer, said the disaster risk reduction and management office decided against recommending the declaration of state of calamity because some criteria were not met, such as the condition that the fish kill should affect at least 20 percent of the population.
- Quinta' aftermath: Deaths, fishkillLocus, Sundy Mae T.; Romero, Maria; Wakefield, Francis T. (Concept & Information Group, Inc., 2020-10-29)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.
- Pollution lang ang dolomiteValmonte, Ric (Manila Bulletin Publishing Corporation, 2020-09-21)Nakakuha kamakailan ng mga patay na isda na tinatayang 10 kilo ng Bureau of Fisheries and Aquatic Resources (BFAR) sa tubig ng Manila Bay sa lugar malapit sa Baseco, Maynila. Nangyari ito sa gitna ng kontrobersiya hinggil sa ginagawa ng Department of Environment and Natural Resources (DENR) na pagpapapaputi ng baybayin ng Manila Bay sa pamamagitan ng pagtatambak ng dinurog na dolomite malapit sa Baywalk, sa kahabaan ng Roxas Boulevard. Ayon kay DENR Undersecretary Benny Antiporda, walang kaugnayan ang kanilang proyekto sa naganap na fish kill.
- ₱12.3-M tilapia lost in Taal Lake fish kill: BFAR monitoring waters off 3 lakeshore townsCinco, Maricar (Philippine Daily Inquirer, Inc., 2019-06-01)At least 150 tons or P12.3 million worth of cultured tilapia turned belly-up in fish cages in Taal Lake in Batangas province due to a low level of dissolved oxygen in the water. The Department of Environment and Natural Resources and the local government of Laurel town in Batangas continued to closely monitor the remaining fish cages after the fish kill occurred in the villages of Gulod and Buso-buso in the last two days. As of Friday, provincial environment officer, Jose Elmer Bascos, said they had yet to dispose all of the dead fish as they needed a larger area to bury them.
- 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.
- Fishkill hits cages in Taal LakeCinco, Maricar (Philippine Daily Inquirer, Inc., 2018-11-06)The local government of Agoncillo town in Batangas province will distribute tilapia fingerlings to local cage operators affected by the recent fishkill in Taal Lake. The incidence of “fish mortality,” a term preferred by local officials in referring to a smaller area where fish turn belly up, occurred at Barangay Subic Ilaya, said Agoncillo Mayor Daniel Reyes. He said 105 cages, out of 1,555 operating in the town, were affected, with about P5 million worth of mature and juvenile tilapia killed in a phenomenon called “sulfur upwelling.”
- 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.
- Fisheries boom hinges on sustainable use of resourcesGalvez, James Konstantin (The Manila Times Publishing Corporation, 2015-07-24)The Department of Agriculture (DA) expects a boom in the country’s fisheries sector as it continues to engage with stakeholders to craft and implement policies and programs for sustainable utilization and management of aquatic resources. With modernization steps to gain momentum for sustainable and inclusive growth, Agriculture Secretary Proceso Alcala is positive that efforts of the government will enable the sector to continue providing a stable supply of food, livelihood, and ecological services. Alcala said the DA, through the Bureau of Fisheries and Aquatic Resources (BFAR), has been instituting measures to ensure that fishing in the country’s waters becomes sustainable and that all forms of fishery resource use provide equitable benefits to stakeholders.
- Cavite takes action against water pollutionGiron, Anthony (Manila Bulletin Publishing Corporation, 2017-02-16)Local government authorities in this city have started efforts to clean rivers in the lowland and upland districts of the province following reports that some tributaries are contaminated by waste and toxic chemicals. River dredging and clearing operations were relaunched in Bacoor District in January as a course of action against floods and pollution in the area. During the launch, waste traps were installed along waterways bounding several barangays (villages) in the district.
