Socio-economic profile of the Philippine National Aquasilviculture Program (PNAP) beneficiaries in Jiabong, Samar, Philippines

A total of 37 beneficiaries under the Philippine National Aquasilviculture Program (PNAP) was interviewed using the structured survey questionnaire of Socioeconomic Monitoring Guidelines for Coastal Managers in Southeast Asia (SocMon SEA). Most of the members of the households are young and in-school. Household heads’ primary occupation is fishing, a shift from mussel farming- the town’s major industry in the past decades. Perceived threat by the beneficiaries is related to the environment specifically typhoon and the problems on waste disposal. It also identified law enforcement as weak leading to dwindling fish catch, mass mortality of mussel, red tide and other problems affecting their primary sources of income. However, they could not relate these phenomena to the most likely causes. The current occupation does not provide sufficient income for the family as they seek for alternative jobs. Garbage and poor implementation of laws are among the identified problems of the beneficiaries.

Crabbing into an uncertain future: the blue swimming crab fisher in coastal town of Eastern Philippines

This research project sought to find out the socio-economic status of the small-scale fishers of the blue swimming crab (Portunuspelagicus) in Samar, considering the diminishing volume of catch of the species in the recent years. Using a blend of quantitative and qualitative methods, the study employed an interview schedule, focus group discussion (FGD) and observation in collecting data not only from the fishers but also from other sectors directly involved in the blue swimming crab industry.

Sur les ondes T des séismes des Philippines enregistrées à Nhatrang

According to the authors, T waves recorded at Nhatrang from Philippine Islands earthquakes may present 3 important phases: F and G, T. and M. If h is the depth of the earthquake, a and b the land paths of T waves respectively near the epicenter and the station, these phases may be noted as: ph-Sofar-SV sub(b) for F and G; P sub(a)-Sofar-SV sub(b) for T sub(2) and problably S in sediments, for M. Sofar waves velocity in China sea, between Philippine and Vietnam, has been determined as to be: 1.48 ± 0.03km
