    Determination of heavy metal (Cu, Cd, and Pb) concentration in musclemeat of fish from different areas in Batan Bay, Aklan
    Bagarinao, Cathrina F. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)
    Food safety is of utmost importance but it is usually compromised by the presence of pollutants in the environment such as heavy metals. This study was conducted to investigate heavy metals concentrations in fish musclemeat collected from different areas of Batan Bay, Aklan. A total of 22 fish species were analyzed for Cu, Cd and Pb using Flame Atomic Absorbance Spectroscopy. Pb concentration in the musclemeat of fish ranged from 0.0292 ± 0.2070- 2.09 ±1.15 mg/kg wet weight and was found to be highest in Mugil cephalus (flathead grey mullet), while Cd concentration ranged from 0.0075 ± 0.0016-0.157 ± 0.209 mg/kg wet weight with highest value in Megalops cyprinoides (Indo-pacific tarpon), and Cu concentration ranged from 0.0605 ± 0.0667-2.76 ± 0.05 mg/kg wet weight, with highest concentration in Leiognathus equulus (common ponyfish). Among the metals, only Pb concentration in flathead grey mullet exceeded the maximum permissible concentration in food as indicated by the Joint FAO/WHO Codex Alimentarius (1984). Assessment of Noncarcinogenic Hazard Quotient (NHQ) gave NHQ values less than 1, indicating that the risk of developing adverse effects due to fish intake is low.

    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.

    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.
