The impact of Sabang Reef Fish Sanctuary in Honda Bay, Palawan was evaluated using fish, coral cover, macro-invertebrates and CPUE as measures for success. Visual census and LIT methods were used for fish, macro-invertebrate and coral cover surveys, while administered interview was used to gather information on CPUE. The protection of fish sanctuary has shown its impact to the coral reef fisheries by the improvement in quantity of the resources. Fishes, macro-invertebrates, and hard coral cover inside the Sabang Reef Fish Sanctuary (Binduyan) showed increased in abundance, diversity, and number of commercial species compared to those outside of the sanctuary. This reflects the positive impact that a protected area gained over four years. Results indicated high exploitation rates of resources in the fished areas just outside the sanctuary. Furthermore, as a consequence of improved reef fisheries, more fishermen fishing in areas closest to the sanctuary have increased their catch.
Sustaining the Coastal Fishery Resources in San Vicente, Palawan
BIMP-EAGA Journal for Sustainable Tourism Development
This study is an inquiry on the “low fisheries productivity” of a potentially resourcerich coastal ecosystem of 1,408 km2 in San Vicente, Palawan, Philippines. Three main coastal habitats, namely: mangroves, coral reefs, and seagrass beds located in four fishing grounds were investigated. Field observations and rapid appraisal methodology using key informant interviews and focused group discussions were involved in the process. A municipal level stakeholders’ validation was done to confirm initial findings. Results showed 8 major fishing gears are operating in 4 bays, of which 5 are passive and 3 are active gears. A total of 103 fish species from 48 families and a major species of squid comprised the catch, of which 60% is reefassociated species. San Vicente’s present fisheries productivity of 1,557.68 metric tons (mt) per year or an extraction rate equivalent to only 1.1 mt/km2/year is far behind its estimated potential yield of 7,040.40 mt per year. In general, the municipal fishi...

Kei Islands located inside the coral triangle. Therefore, the biodiversity level on the sea in this area is considered high. United nation has proposed for water that included in the coral triangle has to apply marine protected area (MPA) to preserve the area. The main problem is most of the community especially in Kei Islands have depended on the sea as their sources of the economy even fisheries commodity like fish play a large part on the inflation rate and other prosperity indicators likes school and housing. Also, Kei Islands practice on form local wisdom for owning areal of the sea which calls "petuanan laut" by certain of villages or group of villages in one area. This study aimed to map the cluster of catching fisheries area based on the quantity of fish supply on a local market in Kei Islands and measure each cluster on their support and perspective on Marine Protected Area (MPA). We conducted a focus group discussion and collecting additional data by questionnaires with descriptive and quantitative analysis with logistic regression. The implication of this study can provide a clear view of coastal communities view on MPA program also to identify an area that has marine resources, human resources, and equipment to provide government an empirical view on catching fisheries in Kei Islands to issued better policy to develop fishing industry in Kei Islands.
The main purpose of the assessment is to establish baseline data to describe the current state of reef fishes, macro-benthic invertebrates and percent cover of live hard corals in the bay. Method applied in the assessment was the method used by English, et al. 1994. Pomacentridae is the most dominant species with 370 individuals: 250 from black damsel and 120 from blue devil damsel, second by Apogonidae (cardinal fish) with 251 individuals. The least species was Zanclidae (banner fish), Haemulidae (sweet lips) and Mullidae (goat fish). Estimated average biomass is very low with 66.01 grams/1000 m 2 using the length-weight relationship and average density of 405 individuals in 1000 m 2. Most dominant macro-benthic invertebrate is Pectinidae (borrowing scallops) with 40 individuals, followed by Oreasteridae (brown starfish) with 31 idividuals and Diadematidae (black sea urchin) with 30 individuals and only one of Ophidiasteridae (sea star and blue starfish). The main percent cover of live hard coral is 31.83%, alike to fair condition if based the standard criteria of coral reef health developed by Gomez and Yap (1998). The data describe that the sites have been disturbed due to the presence of few big fishes. Data is useful as basis in planning and implementation of fisheries management actions.
The Coastal Environmental Profiling (CEP) of Barangay Mana, Malita, Davao Occidental, Philippines
Asian Journal of Research in Agriculture and Forestry, 2024
The study focused on ascertaining comprehensive coastal environmental profile of Barangay Mana, Malita, Davao Occidental. Coastal environmental profiling can help policy-makers design appropriate management strategies in the locality. A self-structured survey questionnaire and key informant interview were articulated to know the stratum of the coastal area in terms of socio- political setting, present natural resources, economic sector, existing people’s organization and management issues and opportunities. Purposive sampling technique was employed for data gathering following one-shoot sampling technique. Mean, percentage and catch per unit effort (CPUE) formula were used in analyzing the findings of the data. Results revealed that the overall population were 5,679 people, their average age is 31.92 and the productive gender is male. The average of their monthly income is Php7, 550.00 and business and fishing activities were common sources of income. An approximate 6 hectares wetland ecosystem were occupied by mangroves and shrubs grown and 1,500m coastline and 0. 4 hectares of estuaries were abundant with seaweeds, seagrasses, mollusks and crustaceans and by which has contributed to building marine species habitat and livelihood. Economic sector was uplifted by 16.32% of fishermen with their volume caught fishes that goes through fermented processing and fish selling. There were four (4) people’s organizations that are engaging with product development and innovation. These People’s Organization aims to generate alternative livelihood income, thereby reduce poverty dense in the barangay. They were likewise supplemented with opportunities designed to fish food security and resiliency and Sustainable Livelihood Programs (SLP) from Local Government Unit (LGU) and National Government Agencies (NGA’s). With the result of the study, it is recommended that Barangay Mana is still in need of various supports from local and national offices in adopting and addressing management issues in both economic and coastal environments.

Marine protected areas (MPAs) are widely advocated as one of the most important tools for conservation and fishery management. Four MPAs were studied: Glan Padidu, Kapatan, Kamanga and Tuka. The status of these MPAs was assessed based on MPA management, ecological health of the coral reef and the productivity of fishermen. Status of MPA management was determined by interviews with the MPA managers and actual validation of the information through actual visit of the areas. Interviews with the fishermen living adjacent to the MPAs were conducted to determine their productivity before and after the MPA establishment based on the catch per unit effort (CPUE). The CPUE of the fishermen increased after five years of well managed MPAs. However, failure in MPA management in two MPAs, followed by the cessation of protection of the areas in 2009, has decreased the CPUE. On the other hand the noninvolvement of the local fisher folks in management of Kamanga MPA created some misunderstanding and unfavorable perception of the fishermen. For them this MPA did not help increase their CPUE as they are allegedly prohibited to fish around the protected areas. Tuka MPA which is relatively well managed among the three MPAs shows an increase in the CPUE of the fishermen.

Healthy coral reefs not only provide abundant fishery resources for small-scale fisheries, but also an additional source income for some fishers who operate recreational tourism. Maintaining coral reef health could be an important concern to ensure sustainability of their livelihoods, especially the poor fishers who are risky to poverty and their needs for income and food security are considerably significant. In this study, semi-structured surveys and focus group meetings were conducted to understand the perception of small-scale fishers on importance of coral reefs and their efforts on coral reefs conservation in Ko Samui and Ko Chang. Although the islands have been influenced with tourism development, small-scale fisheries are still existent. Most of the fishers realized that coral reefs are important for sustaining their livelihoods as their primary sources of food production. Besides, during tourism season, they also gain benefits from tourism-related activities such as providi...
