Second International Marine Bivalve Workshop, Thailand, 2005
In August-September 2005, a two-week workshop on marine mollusks, with an emphasis on systematics, anatomy, and natural history of bivalves, was held in Chanthaburi, Thailand. The goals and format paralleled those of the Florida Keys Bivalve Workshop in 2002, and had the additional goals of increasing understanding of the poorly known molluscan fauna of the Kungkrabaen Bay, Gulf of Thailand, and developing international contacts that might lead to future collaboration. Organizers of the workshop were Bieler and Mikkelsen [coPIs of this proposal] in the U.S., Fred Wells in Western Australia (experienced organizer of numerous marine biological workshops in Australia and elsewhere in the southeastern Pacific), and Kashane Chalermwat in Thailand. Nine trainees worked one-on-one in teams with invited expert scientists on selected bivalve species or groups of species that were determined on site.

The workshop focused on the intertidal habitats of Kungkrabaen Bay, a large bay on the Gulf of Thailand, located in the Ta Mai District of Chantaburi Province (12°32-41'N, 101°52-57'E) and part of a Royal Conservation Project. The bay is 4.6 km long and 2.6 km wide, with a fringing mangrove forest 30-200 m wide and up to 20 m high on the inner bay side. The mangroves are healthy and mixed, including Rhizophora, Sonneratia, Avicennia, and other genera. There is a boardwalk through part of the mangroves which provided ready access to a variety of habitats. Much of the bay emptied during daily spring tides. The center of the bay is soft sediment with a variety of sediment sizes, ranging from fine mud to coarse sand.
The invertebrates, and particularly the mollusks, of these flats are extensively and continuously harvested for food by local inhabitants. Two species of seagrass are found in small quantities in the center of the bay. The deepest part of the bay is 8 m. The headlands to the bay are both rocky, with a diverse assemblage of associated mollusks. The outer margins are sandy shores, with a fisheries research station on the eastern shore that facilitated some of our activities. A small rocky “coral” reef (supporting mainly soft corals) occurs in shallow water near the shore about 1 km south of the fisheries station. Small offshore islands were visited by small boat.
Seven invited scientists mentored one or more students during the workshop. Five of these had participated in the first IMBW in the Florida Keys. Their specialties varied greatly, including systematics, functional morphology, ecology, and population biology. Trainees were selected from a field of applicants on the basis of their credentials and interest in the field of bivalve biology. Including the organizers, the international list of participants included representatives from eight countries. Eleven of the 29 participants were Thai.

Following arrival in Bangkok, participants were bused to the Chanthaburi Campus of Burapha University, 230 km southeast of Bangkok near the Cambodian border. Accommodations, meals, and laboratories were centered here. Double-occupancy dormitory accommodations, laboratories, and classrooms were conveniently located to one another. Labs were well equipped with ample bench space, stereoscopic microscopes, fume hoods, and freezers. Meals (an interesting mixture of Thai and “western” cuisines) were catered, cafeteria-style, in the laboratory building. Three nine-passenger vans with drivers were available to transport participants from campus to various field locations; local fisheries department boats served as dive platforms and contracted commercial boats ferried participants to nearby offshore islands. Easily accessible habitats included extensive mudflats and oyster bars, tidal channels, mangroves, intertidal rocks, sand bars, and offshore rocky reefs. Group and team collecting activities included shovel-and-sieving, snorkeling, scuba diving, and cracking rocks for boring bivalves. Molluscan by-catch from commercial fishing trawls and the Chanthaburi fish market provided valuable additional species for study. Bivalve literature for use during the workshop was supplied by various participants. Most evenings included presentations by participating scientists on their research programs or laboratories. During the last few days, each trainee presented a short summary of the results of their team research at the workshop.
Twenty-two field sites were visited; some of them multiple times by various research teams. Voucher specimens have been deposited in the Field Museum of Natural History, the American Museum of Natural History, the National Science Museum (Bangkok), and the home institutions of participating scientists (including The Natural History Museum, London; National Museum of Wales, Cardiff; California Academy of Sciences, San Francisco; Museo Argentino de Ciencias Naturales, Buenos Aires; Museu de Zoologia, São Paulo, Brazil; and Santa Barbara Museum of Natural History).
From the field and subsequent laboratory results, a dedicated 2008 supplement volume of the Raffles Bulletin of Zoology, a well-respected peer-reviewed journal focusing on the natural history of Southeast Asia, was produced in hardcopy and electronic format. As for the First Bivalve Workshop, most contributions represent the scientific results of projects initiated at the workshop, co-authored by the scientist-student research teams.
