Introduction 1. The SEAFDEC MFRDMD Fourth Regional Workshop on Shared Stocks: Research and Management in the South China Sea was held in Kuala Terengganu, Malaysia, from 24th to 26th January 2000. The main objectives of this workshop are (a) to identify the problems in the management of shared fish stocks in the South China Sea, (b) to identify appropriate management systems for the shared fish stocks in the South China Sea, and (c) to develop appropriate regional fish resources survey mechanisms. 2. The Workshop was attended by delegates from Brunei Darussalam, Indonesia, Malaysia, Philippines, Thailand, Vietnam and Training Department of SEAFDEC; resource persons from FAO, SEAFDEC Secretariat, and MFRDMD, and observers from Department of Fisheries Malaysia, Universiti Putra Malaysia, University College Terengganu, and the DANIDA project on the Assessment of the Living Marine Resources in Vietnam (ALMRV). The list of delegates appears as Annex 1. II. Opening Ceremony 3. Mr Ismail Taufid Md Yusoff, Chief of SEAFDEC MFRDMD, welcomed all the participants to the Workshop. He was happy to have Mr. Hashim bin Ahmad, the Deputy-Director General of Fisheries Malaysia, officiate in the Opening Ceremony, on behalf of the Director-General, because Mr. Hashim has been very much involved and familiar with the affairs of SEAFDEC. The Workshop was also fortunate to have resource persons from the FAO and the SEAFDEC Secretariat, whose presence and contribution were deemed as very important, to help guide the participants on the proper track in carrying out their mission. To ensure the sustainable development of the shared fish stocks, he hoped the fisheries managers of the region would support the work identified for implementation by the fisheries researchers at the national level. The full text of Mr. Ismail's opening address is given as Annex 2. 4. In his keynote address, Mr Hashim bin Ahmad, the Deputy-Director General of Fisheries Malaysia, welcomed all participants to the Workshop on behalf of the Director-General and the Government of Malaysia. He was pleased to note that MFRDMD had started its activities rather early in the new millenium, amidst the still on-going festive mood of the New Year and Eid celebration everyone was presently enjoying. He reiterated that SEAFDEC viewed the convening of regional workshops as one of its more important activities because it fulfilled the needs of the SEAFDEC Strategic Plan in providing a forum for fisheries scientists and managers to meet, plan and formulate suitable programs and activities for the research and management of fisheries resources in the region. The United Nations Convention on the Law of the Sea had stipulated that coastal states were obliged to conserve their marine resources, protect and preserve their marine environment, and cooperate directly or through 1 existing international organizations. He hoped that SEAFDEC through MFRDMD would be able to address such obligations in a more effective manner. He expected the Workshop to provide a strong initiative for what could eventually be a successful program of collaborative activities and mutual benefits for the countries in the region, and wished all participants every success in their deliberations. The full text of Mr. Hashim's keynote address appears as Annex 2a. 5. On behalf of the Director General of Fisheries Malaysia as well as SEAFDEC Council Director for Malaysia, Mr. Hashim Ahmad declared open the Workshop. III. Business Arrangements (a) Adoption of the Agenda and Time Table of the Workshop 6. The Workshop adopted the Agenda and Time Table, which appear as Annex 3. (b) Appointment of Chairpersons and Rapporteurs 7. Mr. Hitoshi Fujita, Deputy Chief of SEAFDEC MFRDMD, Dr. Yasuhisa Kato of the SEAFDEC SECRETARIAT, Dr. Purwito of the FAO, Mr. Ibrahim Salleh of SEAFDEC MFRDMD and Mr. Ismail Taufid Md. Yusoff, Chief of SEAFDEC MFRDMD, were appointed as chairpersons of the workshop sessions; while Dr. Mohd Taupek Mohd Nasir, Dr. Mansor Mat Isa, Mr. Raja Bidin Raja Hassan and Mr. Ku Kassim Ku Yaacob of SEAFDEC MFRDMD were appointed as rapporteurs for the plenary sessions. Dr. Mohd Taupek Mohd Nasir served as the Technical Rapporteur for the whole Workshop. IV. Country Status Reports In Relation To Shared Fish Stocks And Management Experiences Chairperson Mr. Hitoshi Fujita, SEAFDEC MFRDMD (i) Malaysia (Peninsular Malaysia) “The Pelagic Fishery on the east coast of Peninsular Malaysia”- by Ms. Chee Phaik Ean (Annex 4) 8. The paper gave an overview of the status of the pelagic fishery resources on the east coast of Peninsular Malaysia. These resources most probably consist of transboundary stocks since pelagic fish are characteristically migratory in nature. It has also been accepted that many of these stocks are shared by a few countries in the adjacent area. However, after years of meetings and deliberations, problems in the actual assessment and management of these shared stocks still prevail. This report also outlined some of the outstanding problems relating to these aspects. (ii) Malaysia (Sabah) “Marine fisheries resources status: Sabah report” - by Mr. Irman Isnain (Annex 5) 2 9. The 1998 total marine fisheries landings in Sabah was about 196,000 metric tonnes valued at RM 660 million, which was an increase of about 12.5 % compared to the value of 1997. The fishing grounds here are divided into two major zones: the West Coast Zone and the East Coast Zone. The estimated potential yields were around 265,000 tonnes and 85,000 tonnes in the coastal fisheries and deep sea fisheries, respectively. Pelagic species had the biggest component in the marine fisheries sector at about 50% of the yearly marine fish landing, had migratory behavior and were exploited together as shared stocks with neighboring countries. The demersal resources ranged from mid to overexploited level. In terms of value, prawn resources were the most important component in the marine fish production sector. Discussion The Workshop was informed that some differences in the water salinity of Sabah compared to

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.

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.

E-Mail: [email protected]; Tel: +6088-260311; Fax: +6088-240150. ABSTRACT River sand extraction is known as one of the main factors that induces the significant changes on river planform. This paper main objective is to study on the significance of planform changes on Tuaran River from 2003 to 2016 and sediment composition changes due to this activity. The study on channel planform focuses on four single wavelength channel bends which are located at the downstream of Tuaran River. Two meander features which are the channel width (w) and radius of curvature (Rc) were measured from digitized Google Earth satellite image year 2003, 2013, 2014 and 2016 and overlay with the Department of Survey and Mapping Malaysia (JUPEM) topographic map using Geographic Information System (GIS) software and georeferenced to World Geodetic System (WGS) 1984. Four sites which are located at the downstream of Tuaran River were selected to determine the river bed sediments composition. Three of the four sites are located at the sand extraction area whilst one site is a controlled area with no sand extraction activity. River bed sediments were collected and the sediments composition was analyzed using Mann Whitney and Kruskal-Wallis tests to determine the composition difference between the areas and the inner parts of the river.
