  • Geomorphological and sedimentological records of recent storms on a volcaniclastic coast in Bicol, Philippines
    Soria, Janneli Lea A.; Switzer, Adam D.; Pile, Jeremy; Siringan, Fernando P.; Brill, Dominik; Daag, Arturo (Elsevier, 2021-08-01)
    Typhoon Durian in November 2006 was most notable for a series of devastating lahars that buried communities at the base of Mayon volcano in Bicol, Philippines. Typhoon Durian delivered extreme rainfall that remobilized volcanic debris that caused more than ~1200 deaths and extensive property damage. Although not as deadly as the lahar, Typhoon Durian also generated a storm surge that caused localized dune breaching on Malinao barrier sand spit in Lagonoy Gulf. In the absence of instrumental data of the storm surge, we used the geomorphical and sedimentary imprints including erosion scarps, washover fans and terraces to infer the inundation heights on the barrier spit. The surface elevations of washover fans, terraces and relic dunes indicate inundation heights above 1.5 m but not exceeding 3 m. Typhoon Durian's overwash deposit is characterized by typical washover fan stratigraphy, and exhibits horizontal to sub-horizontal lamination on the front to mid-fan and foreset stratification near the fan terminus. Subsurface stratigraphy using shore-normal ground penetrating radar (GPR) imaging reveals at least two buried erosional surfaces farther inland from the erosional surface of Typhoon Durian. Similar to Durian, the older erosional surfaces were probably sustained from previous typhoons. We infer that episodic erosional events most likely have repeatedly disrupted the prograding development of the Malinao barrier spit. Typhoon Durian highlights the exposure of volcanic landscapes to multiple hazards from cyclone landfall.

  • Bulk-buying of sardines mulled
    Romero, Maria (Concept & Information Group, Inc., 2022-09-19)
    Cannery owners are mulling bulk-buying sardines from municipal fishers to sustain their livelihood and keep the cheap prices of the canned goods, a social product that has helped keep Filipino families afloat, especially during disasters and calamities. At a press conference on Monday, Francisco Buencamino, executive director of the Sardines Canners Association of the Philippines, said his group would need the support of the Bureau of Fisheries and Aquatic Resources to support the proposed initiative. “We want to discuss this matter with the BFAR but they are not responsive to our letters. I would love the privilege of having discussions with them. We need to directly agree to craft an agreement, which will also help us avert any crisis,” Buencamino told reporters.
  • Karding aftermath: Veggie, fish, rice prices to go up 20%
    Campos, Othel; Araja, Rio (Philippine Manila Standard Publishing, Inc., 2022-09-30)
    Prices for vegetables, fish and even rice could shoot up by as much as 20 percent as a result of the damage wrought by super typhoon Karding, the Department of Agriculture (DA) warned Thursday. Agriculture Undersecretary Domingo Panganiban said in an interview that the country’s rice granary, Central Luzon, sustained severe damage during the typhoon, resulting in the loss of 20 percent of the standing crop.
  • Quinta' aftermath: Deaths, fishkill
    Locus, 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.
  • Leatherback turtle fished out from Ragay
    Barcia, Rhaydz (The Manila Times Publishing Corporation, 2018-11-23)
    A big leatherback sea turtle weighing 500 kilograms was fished out by local fisherman from the waters of Ragay Gulf in Bicol on Thursday. Nonie Enolva, regional spokesman for Bureau of Fisheries and Aquatic Resources, said the 1.75-meter long sea turtle was found by Alberto Pasamba. Enolva said this was the second time that a leatherback sea turtle was found in the same area of Ragay Gulf.
  • 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.
  • What lies beneath: exploring Benham Rise's unknown treasures
    Cinco, Maricar (Philippine Daily Inquirer, Inc., 2017-03-18)
    Benham Rise, the underwater landmass northeast of Luzon that the United Nations declared part of the Philippines’ continental shelf, has been grabbing headlines because of the presence of Chinese ships that may or may not have been given permission to do research in the area, according to conflicting claims by President Duterte, Defense chief Delfin Lorenzana, as well as Foreign Affairs officials. What remains undisputed, however, are the possible trove of mineral and gas deposits about 3,000 meters below the water’s surface that have yet to be discovered. Sometimes referred to as the Benham Plateau, the landmass, described to have a craggy or rough surface, is bigger than Luzon or almost half the size of the Philippine’s total land area. It extends eastward off the provinces of Aurora and Isabel, and the Bicol region, but has always been connected to Luzon’s landmass through the Bicol and Palanan saddles.
  • Protest staged vs new fisheries policy
    Galvez, James Konstantin; Badilla, Nelson (The Manila Times Publishing Corporation, 2015-09-03)
    Fisherfolk from different provinces trooped to Manila on Wednesday to hold one of several expected “fish holidays” as part of protest actions against the decision of the Bureau of Fisheries and Aquatic Resources (BFAR) to implement the amended Republic Act 8550 or the Philippine Fisheries Code of 1998. More than a thousand fishermen trooped to the Quirino Grandstand in Manila. The protesters came from Navotas, Malabon and the provinces of Bicol region, Masbate, Quezon, Marinduque, Pangasinan, and Cavite. BFAR Director lawyer Asis Perez said in an interview that the agency expects to finalize the Implementing rules and Regulations (IRR) of the Fisheries Code or Republic Act 8550 as amended by RA 10654 next week.
