THESIS ADVISOR : ASSOCIATE PROFESSOR NANTANA GAJASENI, Ph.D., THESIS CO-ADVISOR : CHRISTOPHE LE PAGE, Ph.D., 255 pp. Don Hoi Lord wetland located near Mae Klong river mouth in the area of Samut Songkhram province, upper the Gulf of Thailand. The wetland was registered as the 1099th Ramsar site. Razor clam (Solen spp.) is an important species in the sandbars which are a part of this wetland. Fisherman has harvested razor clam for generating income more than 2 generations. Due to the previous studies, razor clam population has decreased through the time. The objective of this study aims to explore possible sustainable management policies for Don Hoi Lord by using Companion Modelling approach (ComMod). The approach mainly consists of Agent-based simulation model (ABM) and participatory simulation workshop with stakeholders involvement. To achieve the aim of the study, there are 3 parts including: 1) ecological study of razor clam population and its environmental factors especially sediment and particulate organic carbon (POC) between June 2008 – May 2009; 2) socio-economic study to understand fisherman harvesting behavior and razor clam market mechanism; and 3) ABM development from field study finding and test the management scenarios with the ABM. Moreover, the ABM was used in participatory simulation workshop to validate the ABM and to exchange and discuss on razor clam sustainable management.The results from ecological study showed that razor clam population was in crisis due to the decreasing of population. Mean density of razor clam was 0.51±0.30 clam/m2 which has been the lowest record among previous scientific studies since 1982. In addition, razor clam density had negative correlation with %organic matter in soil sediment and particulate sediment in water column (p < 0.05) but it was not correlated with POC. Razor clam market is being driven by a trader who buys all razor clam from a fisherman and processed razor clam as clam meat before distributing to market. The trader set razor clam buying price from fisherman independently based on their razor clam stock and a current market demand. Razor clam demand usually was increased during weekend and, presently the trader distributing processed razor clam to a restaurant and a merchant in fresh market. Regarding fisherman, there were 2 factors affected fisherman’s decision to harvest razor clam, firstly the density of razor clam and secondly razor clam price. Due to the low razor clam density, fisherman had to harvest on other species instead of razor clam but razor clam is still the first priority. The ABM development was done by added i-stage distribution model and re-calibrated until the simulation model represented system behavior. Then, the management scenarios were tested with the ABM and it was found that reserved zoning accompany with quota system was the best scenario for sustaining razor clam population. Next, spatial interface of the ABM was upgraded based on socio-economic finding and the upgraded ABM was used in participatory simulation workshop with stakeholders. The workshop can be a forum for discussion among stakeholders by using ABM as mediator and stakeholders in the workshop which could share their representations for collective agreement to achieve the goal. Finally, the whole process of ComMod at Don Hoi Lord by communicating and co- working between researcher and stakeholders in the field study could help them instituted the group to working on sustainable management by implementing a reserved or forbidden zone on the sandbar at Don Hoi Lord.

    Sedimentary Characteristics of Sand Dune from Bang Berd, Chumphon Province, Southern Thailand

    28 Sedimentary characteristics of sand dune from Bang Berd, Chumphon Province, Southern Thailand Nattawut Prachantasen1, Montri Choowong2*, Santi Pailoplee2 and Sumet Phantuwongraj2 1 International Logging Overseas Ltd., Bangkok, Thailand 2 Department of Geology, Faculty of Science, Chulalongkorn University, Bangkok 10330, Thailand * Corresponding author: [email protected] Abstract The stratigraphy and sedimentary structures within Bang Berd dune field suggest a geological history that includes paleo-storm deposits. The goal of this project is to characterize the sand dunes in terms of their sedimentological features, including grain size distribution, internal sedimentary structures, wind direction indicators and documenting the evidence for paleo-storm deposits in this area. On aerial photographs, the dunes are aligned in N- W and S-E wind directions. Sand dunes here can be divided, on the basis of their geographic position and their morphological features into 3 units, outer dunes, middle dunes and inner dunes. Interestingly, sedimentary structures within the sand dune are very rare; only well developed inclined lamination can distinguish washover deposits from dune deposits. Both wind-blown and washover sands are very fine-grained, well to very well sorted and subrounded to rounded. The deposition of washover deposits that cover the outer dunes that is aligned in an almost east-west direction may indicate unusual paleo-storm pathways strike into the areas based on alternated washover deposits and dune sequence during 93+18 and 126+14 years ago. Key words: sand dune, washover, OSL, Bang Berd 1. INTRODUCTION Sand dunes occur in many environments, including along sea coasts, lake shores and desert. The direction and velocity of wind, in addition to the local supply of sand, result in a variety of dune shapes and sizes (Fritz and Moore., 1987).

They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric tons landed worldwide in 1996. Aquaculture, which mainly concerns bivalves (oysters, scallops, and mussels) relies on the simple techniques of producing juveniles, natural spat collection, and hatchery, and the fact that many species are planktivores.

Taylor Bureau of Commercial Fisheries Biolosical Laboratory U.S. Fish and Wildlife Service, Woods Hole, Massachusetts Introduction Quantitative relations between growth parameters of the cod (Gadus morhua l.) and mean annual sea surface temperature at various localities have been described by TAYLOR ( 1958 a). This paper shows similar relations for a more sedentary organism, the Pacific razor clam (Si/iqua patula). The theoretical "ignificance of such relations is discussed briefl.y. WEYMOUTH and McMILLIN (1931) show age-length data for the razor clam at ten localities ranging from California to Alaska.
