  • Partial mortality in Porites corals: Variation among Philippine reefs
    Wesseling, Ineke; Uychiaoco, Andre J.; Aliño, Porfirio M.; Vermaat, Jan E. (Wiley, 2001-01)
    Partial mortality or tissue necrosis was quantified in the massive scleractinian coral Porites at three sites in The Philippines (Bolinao, NW Luzon; Puerto Galera, Mindoro; and El Nido, N Palawan). Overall, 15 ± 1 (mean ± 1 standard error, 642 replicates) percent of colony area was dead, mean colony area was 1135 plusmn; 127 cm2, and lesion density was 1.7 ± 0.1 dm—2. Total live coral cover varied between 20 and 63% in belt transects, and Porites and Acropora cover were inversely correlated. ANOVA models incorporating effects of site, colony size, sedimentation rates, wave exposure and depth were highly significant but explained only a small proportion of the variation observed in lesion density and percent dead area (respectively 8 and 2%). Lesion density was found to vary significantly with site (contributed 29% to this explained variance), decrease with increasing colony area (33%), and increase with increasing sedimentation (23%) and wave exposure (14%). Colony size was significantly explained by the factor site (contributing 61% to the total 29% explained variance) and depth (34%), with the smallest colonies being observed in Bolinao and the largest in El Nido. Densities of lesions were highest in Bolinao, intermediate in Puerto Galera, and lowest in El Nido. This pattern is parallel to intensity of human reef exploitation and opposite to that in colony size, live coral cover and Acropora cover. Since only a small part of the observed variance in partial mortality estimators was explained by the ANOVAs, other factors not quantified here must have been more important (e.g. disease incidence, predation, human exploitation).
  • Oil spill reaches Verde Island Passage
    Mallari, Delfin Jr; Virola, Madonna; Mangosing, Frances (Philippine Daily Inquirer, Inc., 2023-03-21)
    Traces of oil spill from the sunken MT Princess Empress had reached Verde Island, a six-village islet in Batangas City, which is at the heart of the Verde Island Passage (VIP) where the world’s most critical marine biodiversity center is found, authorities said on Monday. In an advisory, Fr. Edwin Gariguez, lead convenor of the environmentalist group Protect the Verde Island Passage, said they were ready to assist in containing the spill in VIP after residents reported seeing oil sheen and clumps in waters off four villages of Verde Island
  • The lure of mindoro fishermen's ancient way
    Evora, Robert (Philippine Manila Standard Publishing, Inc., 2014-03-24)
    Marginal fishermen in Mindoro Strait are on a roll in the the world’s yellow fin market, attracting buyers with their ancient practice of slapping the sea with their lines and beating expensive commercial operations using modern equipment such as sonars, sensors and nets. The World Wildlife Fund (WWF) said the handline fisherman, who roam the Strait on outrigger boats, catch 70-kilo yellow fin tuna using “kawil” (hook, line and sinker), attracting pelagic fish such as tuna, marlin and mahi-mahi (dolphin fish) in their “payaw” or fish aggregating device. “Tuna buyers from European and Middle East countries as well as Japan and the United States are coming to Mamburao in droves. Mamburao is now the de facto tuna capital of the Philippines,” said Joselito Tiongson, site manager of the WWF.
  • Agri chief assures Metro food supplies ‘more than enough'
    Gomez, Eireene Jairee; Valente, Catherine S. (The Manila Times Publishing Corporation, 2020-03-14)
    The Department of Agriculture (DA) on Friday assured the public that the community quarantine had not affected food supplies for Metro Manila. “We have determined that there is enough supply of all basic goods that can be traded in Metro Manila,” Agriculture Secretary William Dar told a news briefing in Quezon City. Fish demand is at 8,000 MT per week, with supply at 10,264 MT per week. The stocks come from Ilocos, Mimaropa (Mindoro, Marinduque, Romblon and Palawan) Central Luzon, Bureau of Fisheries and Aquatic Resources and Philippine Fisheries Development Authority-Navotas.
