    Gender analysis on the modes and extent of participation in Community-based Fishery Resource Management (CFRM) project in Malalison island, Culasi, Antique
    Benliro, Patriana Z P.; Eraste, Concepcion E. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
    A Gender Analysis on the Modes and Extent of Community Participation on CFRM in Malalison Island, Culasi, Antique was conducted in June 2002-Feruary 3003. The study aimed to determine the modes and extent of participation in Community- based Coastal Resource Management through the Community-based Fishery Resource Management (CFRM) Project using Program Monitoring with interview and focused group discussion. The difference on the modes and extent of participation of sex and membership in the association was also assessed. The study found out that male and female modes of participation in CFRM had no significant difference. The difference was in the extent of their participation, which was caused by the social roles they played. On the other hand membership in the organization was found to be a significant variable in analysing the modes and extent of participation.

    Mangrove community structure survey in Iloilo River
    Bayate, Bryna Kimberly L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-04)
    Mangroves are highly productive forests growing along tropical tidal mudflats and shallow water coastal areas where water is generally brackish. The structure of the mangrove stand in the Iloilo River was studied using the transect line plot method with 55 plots established in the 3 out of 4 stations of the river. Community Structure is described in terms of the following parameters: basal area, stems per hectare, relative density, relative frequency, relative dominance and importance value of the species and the Shannon Index of Diversity. Variations in these parameters are correlated with certain physico-chemical factors- soil and water temperature, soil and water pH, and water salinity.Nineteen(19) true mangrove species were found in the area belonging to 10 families. These include Mysinaceae family represented by Aegiceras corniculatum ; Avicenniaceae family represented by Avicennia alba, Avicennia marina, Avicennia officinalis and Avicennia rumphiana; Euphorbiaceae family represented by Excoecaria agallocha; Sterculiaceae family represented by Heritiera littoralis; Combretaceae family represented by Lumnitzera racemosa; Palmae family represented by Nypa fruticans; Rhizophoraceae family represented by Bruguiera cylindrica Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa; Sonneratiaceae family represented by Sonneratia alba, Sonneratia caseolaris, and Sonneratia ovata.Ruciaceae family represented by Scyphiphora hydrophyllacea and Meliaceae family represented by Xylocarpus granatum, and Xylocarpus meckongensis. Avicennia officinalis has the highest total basal area of 650.69m2/ha, Avicennia alba, Aegiceras corniculatum, Avicennia marina, Avicennia officinalis, Avicennia rumphiana, Exoecaria agallocha, Lumnitzera racemosa, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Sonneratia alba and Xylocarpus moluccensis have equal relative frequency of 0.074. Avicennia marina obtained the highest stems per hectare with a value of 38933.33, relative density of 0.405 relative dominance of 0.332 and importance value of 0.913. The index of diversity is 1.010, indicating that the area is diverse.

    Cost structure and profitability of oyster farming in Panay, Capiz
    Baes, Jese B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2002-03)
    The study focused on the economic analysis of oyster farming; particularly productivity, costs and returns, income, and employment aspects as they relate to different farm sites, farm sizes, and methods of culture in Panay, Capiz. A total of 27 oyster farmers were interviewed. Results revealed that the value of production per farm was estimated at P50,855, greatest in Butacal and least in Bantigue. By farm size, it appeared that the small farms were more efficient per unit area. The combination of broadcast, stake and hanging methods yields the highest crop per farm. Oysters harvested from the farm were primarily sold. About 5% were given away to friends, relatives, or paid for services, and family members consumed only 2%. Consisting mostly of boat/raft and plots, farm investment was relatively low in Agojo/Tanza Norte than in other farm sites. Butacal had the largest investment of P49,803 per farm. Investment per unit area was relatively less for the bigger farms. The hanging method required the least investment while the broadcast with stake appeared to be the most costly. Hired labor and food were the major variable inputs, depreciation accounted for fixed cost and opportunity cost primarily included opportunity cost of investment. Total expenses per farm averaged P5,623. By farm size, total costs were lower in larger oyster farms. As the farm size increased, expenses also increased while per unit area decreased with increasing farm size. Oyster farmers using the broadcast with stake method incurred the largest farm expenses. Gross income was estimated at P49,961 per year. A direct relationship between farm size and gross income exists. By method of culture, the combination of broadcast, stake and hanging methods earned the highest gross income. The same relationships as that for gross income were observed in the analysis of the net income. On the average, an oyster farmer received a gross profit of P49,727 and a pure profit of P45,232. Gross and pure profit increased with farm size. The combination of the broadcast, stake and hanging methods earned the highest pure profit of P79,511 Small- sized farms and farms that used the hanging method received negative pure profits. The study recommends that the government should take steps to improve the performance of the farms especially with the low-income farm sites and should seek ways of advancing the socioeconomic condition of oyster farmers. Likewise the municipal governments should properly implement the monitoring of oyster farms to check the socioeconomic conditions, the plans of the oyster farmers, and the obstacles they encountered toward the improvement of their business. Researches directed at enhancing the productivity levels of oyster farming should be given priority. Oyster farming being a part-time activity must be complemented with programs that encourage alternative income sources

    Willingness-to-pay for the conservation of mangrove site in Dumangas, Iloilo
    Agapito, Arianne I.; Guadalupe, Ronell D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    This study was designed to determine the willingness-to-pay of the residents of Dumangas, Iloilo for the conservation of the existing mangrove sites in their area. Data were gathered through personal interviews using an interview schedule among 240 household representatives equally distributed in six barangays: three coastal, three noncoastal. Results of the study showed that most of the study participants were aware and knowledgeable about the existence of mangroves, its uses and benefits. The popular barangays identified to have mangrove sites included Sapao (31.33%) and Ermita (32.92%). Using dichotomous choice willingness-to-pay method with randomly assigned bid prices, results showed that most of the study participants both from coastal (89.17%) and non-coastal barangays (91.67%) were willing to pay for the conservation of mangroves. The main reason cited was that they want to participate in programs by the local government that aims to conserve the environment. When adjusted to level of certainty, there was slight difference in the number of study participants who were willing-to-pay; mean willingness-to-pay amounted to Php 86.47 without adjustment to level of certainty and Php 76.17 when adjusted to level of certainty. Knowledge index rating, civil status and bid price were the significant factors that affect the willingness-to- pay without adjustment to level of certainty at 5% level of significance. When adjusted to level of certainty, knowledge index rating (5%) and bid price (1%) were the significant factors. Annual surcharge in Community Tax is the preferred payment vehicle of the study participants for the conservation.

    Cost analysis of coral gardening in Bato Bukay MPA, Guimbal, Iloilo
    Acob, Philina Riva L.; Rojas, Jan Katherine C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)
    This study analyzes the costs of coral gardening in Bato Bukay MPA in Guimbal. Iloilo. Cognizant of the degradation of their coastal areas and fisheries, the community of Bgy Nalundan, where the marine protected area is located, sought to find solution through marine conservation and coral gardening. Being the habitat and breeding grounds of fishes, coral reefs are one of the most important natural resources that people must protect. Hence, several projects were implemented to propagate the establishment of Marine Protected Areas such as the deployment of artificial reefs and coral gardening activities. Costs of coral gardening in the site were estimated using key informant interviews with individuals who were involved with or who were knowledgeable on the establishment and maintenance of the project, and from secondary sources, thereby enabling the computation of the total costs. A survey of randomly selected participants that included Contingent Valuation Method was conducted in barangays Nalundan, Calampitao and Cabubugan, to determine the socio-economic profile and estimate the local community support through their willingness-to-pay and willingness to support in kind. Proportional sampling formula, adjusted to small population was used to determine the number of these participants across the barangays. The total cost for coral gardening on its first year was estimated as Php 336.684 combining all the fixed, variable and opportunity costs incurred. Out of the total costs, 40% amounted as fixed costs, while 33% were variable costs, and 27% constituted opportunity costs. More people were willing to pay in-kind by volunteering than to pay in monetary terms for the project’s fund for sustainability.
