Soliman1*, Antonino B. Mendoza, Jr.1 and Kosaku Yamaoka2 1 Coastal Resouces management Unit, Bicol University Tabaco Campus, (Tabaco, Albay 4511, Philippines) 2 Graduate School of Kuroshio Science, Kochi University (Monobe, Nankoku, Kochi 783-8502, Japan) Abstract Lagonoy Gulf is a major fishing ground in the Philippines. It is large (3071 km2) and deep (80% of its area is 800-1200 m) where channels opening to the Pacific Ocean are entrenched. Its annual fishery production of 26,000 MT in 1994 slightly decreased to 20,000 MT in 2004. During the same 10-year period, catches of higher order, predatory fishes decreased and were replaced by herbivores and planktivores. Scombrids such as tunas and mackerels composed 51-54% of total harvest. Of the 480 fish species identified in the gulf, 131 or 27% are seaweed-associated or these fishes have utilized the seaweed habitat for juvenile settlement, refuge, breeding and feeding sites. The seaweeds occupy solely distinct beds (e.g., Sargassum) or overlap with seagrass and coral reef areas. About half of all fishes (49.6% or 238 species) are coral reef fishes. The most speciose fish genera are Chaetodon (19 spp.), Lutjanus (18 spp.), Pomacentrus (17 spp.) and Siganus (14 spp.). Among them, Siganus (Siganids or rabbitfishes) is the most speciose, commercially-important genus contributing 560 mt-yr-1 to the total fishery production, including about 60 mt siganid juvenile catch. -
The Status of Mollusk Diversity and Physical Setting of the Mangrove Zones in Catanduanes Island, Luzon, Philippines
BIOTROPIA Vol. 17 No. 2, 2010: 62 - 76 THE STATUS OF MOLLUSK DIVERSITY AND PHYSICAL SETTING OF THE MANGROVE ZONES IN CATANDUANES ISLAND, LUZON, PHILIPPINES JIMMY T. MASAGCA1,2 ANGELICA V. MENDOZA² and ESTRELLA T. TRIBIANA² ¹Pacific Island Institute for Pedagogy, Technology, Arts & Sciences, Inc. De La Salle University-Dasmarinas,~ Philippines ²Catanduanes State Colleges, Calatagan, Virac 4800, Catanduanes, Philippines Received 06 August 2010 / Accepted 13 September 2010 ABSTRACT The status of mollusk diversity and physical setting of mangrove areas in Catanduanes island, Luzon (Philippines) are described. A total of 57 species of mollusks, consisting of 27 gastropods and 30 bivalves were recorded in the island. Registering higher values of species diversity indices (Margalef) and species richness (Menhinick) are the prosobranch, Terebralia sulcata; corbiculid bivalve, Geloina coaxans; potamidiids, Cerithidea cingulata and Cerithidea rhizophorarum; and two other species of the genus Littorina (Littorinopsis). Using the physiographic model, majority of the mangrove areas under study follow the composite river and wave-dominated setting with some few areas having the wave-dominated, tide-dominated allochthonous setting. Keywords: Mollusk diversity, mangrove areas, Philippines INTRODUCTION In recent years, there had been an increased interest on the status of mangrove areas in tropical coastal ecosystems for economic and ecologic reasons (McNeely et al. 1990, Maler 1997, Masagca 2006). These are the most biologically diverse of all marine ecosystems but are being degraded worldwide by human activities potentially leading to numerous extinctions (Rios-Jara 2009). Conservation efforts targeted toward these ecosystems could help in averting the loss of tropical biodiversity. The first step according to Hamilton and Snedaker (1984) towards the attainment of the goals of conservation and sustainable use of the mangrove ecosystem is to develop data base. -

Slope Stability Analysis for Remediation Project Along the Catanduanes Circumferential Road Network System
Slope Stability Analysis for Remediation Project Along the Catanduanes Circumferential Road Network System Dexter M. Toyado MSCE-Geotechnical University of the Philippines, Diliman, Quezon City, Philippines ABSTRACT This paper attempts to (1) Analyze Slope Stability, Landslide Susceptibility, and Soil Nails application, (2) Provide a numerical analyses, visual views and interpretation of Slope Stability problems and Factor of Safety, (3) Offer technical and comprehensive solutions of the identified unstable slopes confronting the road network system for remediation projects. The Landslide Susceptibility Map (LSM) along the Catanduanes Circumferential Road Network System (CCRNS) showed that Parts of Tubli-Dariao- Guiamblong Area, Hitoma Area and San Andres Area where the CCRNS is situated indicates moderate to high susceptibility to landslide. The Landslide Simulation along these areas shows that the Factor of Safety (FS) is highest in both the 30, 40 and 50 degrees slopes when the water level is just below the top layer and lowest when the water level is at the ground surface. When the water table is at the midpoint of the Top Layer, the FS in all areas has an average of 1.157, 0.972, and 0.934 in both 30, 40 and 50 degrees slopes, respectively. This safely suggests that the increment of water level or saturation of soil contribute to slope failure. It is evident that when the rainfall occurs and when it saturates the soil, a very high potential of slope failure will occur on the slopes along the CCRNS. The saturation on the soil type that is found in the province is about 50 mm per day at the average. -
Background Research Report on Northern Catanduanes Bicolano
DigitalResources Electronic Survey Report 2015-002 Background Research Report on Northern Catanduanes Bicolano Leslie Gumba Background Research Report on Northern Catanduanes Bicolano Leslie Gumba SIL International® 2015 SIL Electronic Survey Report 2015-002, September 2015 © 2015 SIL International® All rights reserved Abstract The Northern Catanduanes Bicol language has been a subject of interest for several decades. The language was surveyed in the mid-1980s, and the speakers reportedly were found to be mostly bilingual in either Tagalog or the Southern Catanduanes Bicol [bln] language, the more widely spoken language of the area. The present assessment confirms that the past situation still exists but also indicates that language documentation is desired, possibly along with literature production. This would certainly be needed if the Philippines Department of Education implements mother tongue based multilingual education in the schools of Northern Catanduanes [cts]. iii Contents Abstract 1 Introduction 1.1 Name of people 1.2 Location 1.2.1 Bagamanoc 1.2.2 Caramoran 1.2.3 Pandan 1.2.4 Panganiban 1.2.5 Viga 1.3 Church, mission history and NGOs 1.4 Population and demography 1.5 Politics 2 Languages 2.1 Language name, alternate names and dialects 2.2 Language attitudes and relations to other languages 3 Sociolinguistic context 3.1 History 3.2 Education and literacy 3.3 Studies and research 4 Conclusion and recommendations References 1 1 Introduction The purpose of this study is to review previous research and other background information about the Northern Catanduanes Bicol [cts] language, in order to determine if there is a need for the Translators Association of the Philippines to undertake a project. -
Conservation Practices at Agojo Marine Park and Sanctuary in Catanduanes, Philippines: Convergence of Initiatives for Eco-Governance
Conservation practices at Agojo Marine Park and Sanctuary in Catanduanes, Philippines: Convergence of initiatives for eco-governance S.R. Vargas¹, A.V. Asetre² ABSTRACT The Philippines has gained international recognition and respect as a country giving high premium to natural resources management. In the Bicol Region, the most popular strategy for coastal resource management is the establishment of marine protected areas (MPAs). The oldest of this is the Agojo Point Fish Sanctuary and Marine Reserve (APFSMR) strategically located along the Lagonoy Gulf of the island province of Catanduanes. The establishment of the MPA in 1993 has holistically addressed the management and conservation issues in the area. Substantial recovery from the previously damaged conditions of the fragile coastal ecosystem has restored biodiversity of its natural resources and has significantly contributed to the enhancement of the quality of life of the stakeholders on the adjoining communities in the municipality of San Andres, Catanduanes. This tangible reward experienced by the residents brings forth dramatic positive change in their attitudes to support the management and conservation initiatives of local government units (LGUs), other government organizations, non-government organizations, people’s organizations, and academic institutions, actively advocating for environmental conservation and protection, building partnerships for the sustainable development of marine resources, and promoting empowerment of coastal communities. Different interventions in the MPA under consideration were employed by the different sectoral groups composed of LGUs, the Philippine Department of Agriculture (DA), mangrove organization, the US Embassy/US Peace Corps Volunteer Program, the Catanduanes State Colleges, Youth Science Clubs, Republic of the Philippines (RP) KR2 Program and the Philippine Bureau of Fisheries and Aquatic Resources (BFAR). -
Value Chain Analysis of Pen Shell (Baloko) in the Province of Sorsogon, Philippines

Amano1,* and Julieta V. Mojados2 1Bicol University Jesse M. Robredo Institue of Governance and Development, Legazpi City 2Bicol University College of Business, Economics and Management, Legazpi City *Corresponding author: [email protected] Abstract Sorsogon Bay is home to the pen shell (Atrina pectinata), locally known as Baloko. This study was designed to assess the existing value chains of pen shell and identify areas for improvement. The sites covered were the municipalities along Sorsogon Bay in the province of Sorsogon, Philippines. It employed the tracer methodology where only the processors and fisherfolks connected to the traders were selected as respondents of the study. Primary data were gathered through semi-structured questionnaires. Secondary data were used to establish a good understanding of the pen shell industry in the areas of the study. Results show that the adductor muscle or tinga is a substitute for scallops, thus, an export product. The other parts of pen shell or rambit are also of high demand. The highest volume of pen shell catch occur during October to April during the northeast monsoon (amihan) and gradually decline from May to September during the southwest monsoon (habagat) months. The value chain maps reflect the whole meat and semi-processed value chains, the two distinct marketing practices traced in the pen shell industry. -
