- Baseline assessement of Dauins Marine Protected Areas, PhilippinesPublication . FERRANDIS, Ella; Paulo, DiogoNo-take Marine Protected Areas (MPAs) have been established as a management strategy to conserve biodiversity and sustain fisheries. When properly managed, such areas can maintain or increase reef productivity. A total of seven Marine Protected Areas have been established on the coastline of Dauin, Negros Oriental, Philippines. These seem to have been successful in reducing fish stock exploitation by local and international fishermen. Each MPA, however, covers an average of 6.69Ha, far smaller than is recommended for effective MPAs. This is compounded by the common practice of fishers placing longlines at the MPA boundaries. This thesis project would compare fish diversity, size, and biomass in addition to coral diversity and coral cover within and outside the MPA systems. In parallel, an assessment of the external risks and impacts that reefs within these MPAs are exposed to will be performed during the study. In total, one dry season (February to July 2019) and one wet season (August 2019 to January 2020) of data were analyzed. Coral Point Count with Excel extensions (CPCe) were used to investigate substrate composition. Diver Operated Stereo Video System (SVS) and EventMeasure measured fish biomass, diversity, and abundance. 3-Dimensional reef modeling, using AgiSoft were applied to obtain values of rugosity and slope. SCUBA helped search to identify the root causes of coral mortality (coral bleaching, coral disease, trash, corallivorous invertebrates). The data collection was carried out by researchers from the Institute for Marine Research (IMR) located in Dauin, Negros Oriental, and by myself, under their supervision. A high variability between the study sites have been noted. Added to the underrepresentation of the unprotected sites (three vs fourteen MPAs), this report constitute therefore a descriptive overview more than a proper significant comparison between Dauin’s MPAs and non-MPAs. The results obtained underline the need to continue studies on the Dauin coast in order to assess the effectiveness of MPAs and to guide the stakeholders towards better enforcement measures and respect for the protection status of MPAs already implemented. Indeed, make a case for the unification of MPAs to create a much larger area seems to be an option that would benefit not only marine biodiversity, but also the local population who depend heavily on the reef for their livelihood.
