    An assessment of the fishery ordinances of the different coastal municipalities in the Province of Iloilo, 1992-1998
    Almero, Flora B.; Gerona, Ma. Leda G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-12)
    This research project is an assessment of the fishery ordinances of the different coastal municipalities in the Province of Iloilo. The study covers the fourteen (14) coastal municipalities of the Province namely; the Municipality of Anilao, Banate, Barotac Nuevo, Barotac Viejo, Batad, Carles, Concepcion, Dumangas, Estancia, Miag- ao, Oton, San Dionisio, San Joaquin and Tigbauan. The primary data were taken from the various municipal fishery ordinances of the different coastal municipalities under study, and the national fishery policies (RA 7160, PD 704, RA 8550). The researchers also employed field interviews with selected fisherfolk leaders as a source of first hand information concerning the recent situation of the fishery industry in their respective municipalities. It was found that: (1) the fishery industry in the Province of Iloilo is facing problems on overexploitation, overfishing, pollution, and habitat destruction; (2) the primary concern of the over-all policy mosaic for the fishery industry is the rehabilitation and protection of the coastal environment, the limitation of access to fishery resources comes as the secondary concern, while the protection of the rights of municipal fisherfolk appears in a very limited number of promulgations only; (3) generally the provisions in the over-all policy mosaic is consistent and complimentary, both vis-a-vis the national fishery policies and within their respective municipal fishery ordinances where the provisions belongs. Assessing the municipal fishery ordinances of the different coastal municipalities in the Province of Iloilo, it was found that the goal of the over-all policy mosaic is the promotion of sustainable development for the fishery industry so as to achieve food security in terms of fish.

    Comparison between commercial pellets and golden apple snail pellets as food for Tilapia nilotica fingerlings
    Arboleda, Daphne A. (Dision of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1997-04)
    The viability of Golden apple snail as food for Tilapia nilotica was determined by comparing it with commercial pellets. The experiment was conducted on February 3, 1997. The two treatments had three replicates each with a stocking density of 15 fingerlings each. Comparison of growth curves showed that fingerlings fed with commercial pellets grew significantly (P< 0.01) faster than those fed with golden apple snail pellets. The computed FCR was also greater for commercial pellets. The results suggest that golden apple snail alone does not promote efficient growth in Tilapia nilotica fingerlings. Thus it is recommended that golden apple snail be combined with other food ingredients to enable its efficient utilization as a protein source.

    Fish farming and the fish community: The case of Victorias, Negros Occidental
    Apawan, Maylanie D. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2001-04)
    The rapid expansion of aquaculture in the past decades has brought about some economic benefits, but it has also resulted in various social and environmental problems. This observation points to the need to look at aquaculture development beyond conventional measures emphasizing economic benefits; there is a need to focus on the interplay of social, economic, and environmental factors in looking at aquaculture development. This study looks at the social, economic, and environmental impacts of aquaculture on small fishers in three coastal villages in Victorias, Negros Occidental and examines the responses of small and subsistence fisherfolk to the growth and proliferation of fish farming. The study points out the social and environmental issues usually arise as a consequence of conflicts between fish farmers and small fishers in the use of land and water and also because of the effluent charge and chemical residues coming from fishpond operations. When contextualized within a larger set of social and ecological issues, these conflicts have wider implications, especially when these involve unequal distribution of costs and benefits among different stakeholders.

    A survey of the catch composition of fyke nets in the Iloilo river
    Andrada, Kristina Abelaine D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-04)
    A survey of the catch composition of fyke nets in the Iloilo River Estuary during the months of August 1999 and February 2000 show that catches are dominated by Metapenaens crisis and ilossygobius sp. The 18 species caught are : 9 fish species, 5 shrimp species, and 4 crab species. The index of similarity 0.3 between the monthly samples is low which means that there is minimal degree of similarity between the species composition of the catches. There is no significant difference between the total catch volumes per day for the months of August 1999 and February 2000 which means that the seasons do not affect the volume of the catch.
