    Abundance, distribution, and composition of macrobenthos in Banate Bay, Iloilo, Philippines
    Bernasol, Mylin M. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
    In order to characterize the macrobenthic community in Banate Bay, quarterly sampling was done from December 2012 to December 2013 in nine (9) stations of the study area. Samples were collected using a hand-held mud corer measuring 0.15m in diameter. Samples were sieved in the field using a 0.5mm mesh, preserving all retained organisms in a plastic container containing 10% buffered formalin with Rose Bengal dye. Two (2) replicate samples per station in June and September 2013 were processed in the laboratory. A total of 38 taxa were sorted and identified with overall mean density of 821 ind/m2. Cluster Analysis using the program COMM grouped species according to their abundances and stations based on their relative location from the shore. T-test for 2 sample means showed that densities in June and September did not differ significantly (p=0.42). ANOVA showed that densities per station did differ significantly (p=0.05). Correlations identified salinity, dissolved oxygen, turbidity, and organic matter content to have negative effects on macrobenthos density in the Bay. In spite of low density, diversity particularly of polychaetes appeared to be relatively high. This can be attributed to the intensity and fluctuations of the harsh environment in the Bay still being within limits.

    Implementation of marine-protected area in San Jose, Antique: A social analysis
    Azucena, Jessa Veeh B.; Moreno, Rosano Carlo P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)
    This study was designed to evaluate the marine protected area (MPA) implementation in San Jose, Antique using socio-economic and governance indicators. Data were gathered through personal interview of fishers using an interview schedule and focus group discussion (FGD) with selected participants from the municipal government and barangays. A total of 125 fishers were chosen from the four barangays affected by the MPA, namely: Brgy. 3, Brgy. 4, Brgy. Madrangca and Brgy. Funda Dalipe through systematic random sampling. The results showed that the presence of the MPA have not made a significant change in the income of the fishers. Fishers believed that fish abundance and fish catch is relatively higher in 2003 compared to the present. Marine resources are highly valuable to the fishers since it is their source of income (64%) and food (33%). They also believed that the resources are already depleted (51%) due to uncontrolled fishing (28%). In addition, the management plan was not followed. There was no specific budget intended for MPA. There was a low degree of participation and stakeholder empowerment. Also, it was observed that though most (91%) of the fishers were aware of the MPA, there was less involvement in MPA activities, particularly of the fishers from Brgy Madrangca, Brgy 3, and Brgy. 4. To improve the MPA management in the area, there should be provision of income diversification program in the coastal barangays, proper information dissemination, a specific budget intended for the MPA and involvement of all the affected barangays.

    Spatial variations of Benthic meiofauna communities from Palompon Bay, Northern Leyte
    Balasa, Melvy June (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    Meiofauna play a significant role in maintaining ecological balance in marine ecosystems especially in the dynamics of the seagrass meadows. The meiofauna links the upper trophic level with detritus-feeding organisms. Only few studies have been conducted in the Philippines, while no studies have been. This study was conducted in Palompon, northern Leyte in November 2011, to determine the spatial distribution of meiobenthic fauna in the area and to compare community structure in terms of species composition, species density, and species diversity among five stations included in the survey. Twenty taxa were identified with nematodes being numerically dominant, followed by harpacticoid copepods. It also showed the highest mean abundance for the entire habitat type. The overall mean density was 194585.1528 ind. m2, with the highest population at station 4. And the lowest population was recorded at station 2. Soft bottom habitat showed the highest recorded mean density among the 5 stations, Harpacticoids mostly dominated sandy substrate while nematodes were widely distributed.
