Proceedings of the Regional Workshop on the Management of Sustainable Fisheries for Giant Clams (Tridacnidae) and CITES Capacity Building Six species of giant clams © WorldFish Center Executive Summary At its 14th meeting held in the Hague, the Netherlands in June 2007, the Conference of the Parties to CITES adopted decision 14.80 that directed the CITES Secretariat to seek external funding to enable a workshop to be held in the Pacific, in collaboration with appropriate regional organizations, to initiate regional cooperation on the management of sustainable fisheries for giant clams (Tridacnidae). Subsequently, from the 4–7 August 2009, the Regional Workshop on the Management of Sustainable Fisheries for Giant Clams (Tridacnidae) and CITES Capacity Building was held to identify national and regional initia- tives that could ensure the long-term ecological, social and economic sustainability of this important fishery. This is particularly important as Pacific Island Countries and Territories (PICTs) have now been supplying the world’s aquarium industry for over 30 years with an increasingly diverse range of wild and cultured commodi- ties, in particular, giant clams. Culture methods are also continuing to evolve for commercial production giant clams for meat or the aquarium trade . The four-day workshop involved technical consultation between a wide range of stakeholders, including gov- ernment, private and public sectors; and specialists who are active in the production of giant clams for the global marine aquarium trade in the Pacific Region. Attendance included representatives from the American Samoa, Australia, the Cook Islands, the Federated States of Micronesia (FSM), French Polynesia, Fiji, Kiribati, New Caledonia, Papua New Guinea (PNG), Palau, the Republic of the Marshall Islands (RMI), Samoa, the Solomon Islands, Tonga, and Vanuatu. All species of giant clams have been listed in Appendix II of CITES since 1985 and international trade in live specimens, meat or shells is thus regulated. In accordance with Article IV of CITES, the export of any specimen requires the prior grant and presentation of a CITES export permit. Permits may only be issued after a non- detrimental finding has been made by Scientific Authority of the State of export. The proper implementation of Article IV is essential for the conservation and sustainable use of Appendix-II species. The IUCN also lists the giant clams as vulnerable. Currently, Fiji, Palau, PNG, Samoa, the Solomon Islands and Vanuatu are the only sovereign countries in the Pacific that are signatories to CITES. RMI and Tonga are interested in joining because of the difficulties they are experiencing in exporting their cultured giant clams. Capacity issues experienced by PICTs are impacting on their ability to effectively implement and enforce CITES. They are also experiencing challenges in maintaining sustainable wild harvest fisheries for giant clams; and all would like to be able to promote the culture of giant clams further.

Ils sont répartis dans des habitats constitués de récifs coralliens peu profonds, dans des eaux comprises entre 25°C et 30°C. La lumière est une ressource indispensable aux bénitiers. Elle permet la photosynthèse des zooxanthelles. Les zooxanthelles sont des algues symbiotiques situées dans le manteau et produisent des éléments nutritifs aux bénitiers. Depuis quelques années, la surpêche pour l’alimentation essentiellement destiné au marché asiatique a entrainé la disparition de certains stocks naturels. C’est pourquoi depuis 1983, les bénitiers toutes espèces confondues, ont été inscrits sur la convention internationale sur le commerce des espèces en danger, au niveau international. Lors de cette étude, nous allons analyser les techniques de transports de bénitiers pour le marché aquacole, au niveau local (transport inter-iles) mais également à plus grande échelle au niveau international afin de permettre de développer l’ouverture de nouvelles zones de productions, en améliorant les taux de survie. Toujours dans cette thématique de gestion de stocks de bénitiers, nous avons aussi réalisé un réensemencement en ile haute afin d’étudier la faisabilité et la viabilité de projets de repeuplement sur le long terme.

  • Giant Clams1
    CHAPTER 13 Giant Clams1 John L. Munro I. INTRODUCTION In the past decade there has been an enormous upsurge in interest in the giant clams (Family Tridacnidae), resulting largely from the realization that their artificial propagation is technically feasible (La Barbera, 1975; Jameson, 1976; Beckvar, 1981; Gwyther and Munro, 1981), that growth rates of the larger species are relatively rapid (Munro and Gwyther, 1981) and that, by virtue of their symbiotic relationship with a species or species group of dinoflagellate algae,theyaretheworld'sonlyself-feedingfarmanimals(Munro, 1983). These factors combined with the realization that stocks of the larger species had been dramatically depleted in most parts of the South Pacific, both by poachers intent on supplying the lucrative Taiwanese market for giant clam adductor muscle and by continuing local harvests by expanding populations of South Pacific Island­ ers, led to a number of research projects being launched at various institutions in the region; notably at the University of Papua New Guinea and the Micronesian Mariculture Demonstration Center in Palau (both in 1976), by the International Center for Living Aquatic Resources Management (ICLARM) in 1983 and by the Australian Center for International Agricultural Research (ACIAR) in 1984. As a result of these collective efforts, there is a substantial body of informa­ tion available on many aspects of the biology and ecology of giant clams and a reasonable understanding of the factors which constrain the intensive harvesting of giant clam stocks for commercial or subsistence purposes. It is now techni­ cally feasible to spawn routinely mature giant clams and raise the larvae through their juvenile stages to maturity (Heslinga and Fitt, 1987).

  • Supplement – December 2017 – Survey of the Literature on Recent
    A Malacological Journal ISSN 1565-1916 No. 36 - SUPPLEMENT DECEMBER 2017 2 SURVEY OF THE LITERATURE ON RECENT SHELLS FROM THE RED SEA (third enlarged and revised edition) L.J. van Gemert* Summary This literature survey lists approximately 3,050 references. Shells are being considered here as the shell bearing molluscs of the Gastropoda, Bivalvia and Scaphopoda. The area does not only comprise the Red Sea, but also the Gulf of Aden, Somalia and the Suez Canal, including the Lessepsian species in the Mediterranean Sea. Literature on fossils shells, particularly those from the Holocene, Pleistocene and Pliocene, is listed too. Introduction My interest in recent shells from the Red Sea dates from about 1996. Since then, I have been, now and then, trying to obtain information on this subject. Some years ago I decide to stop gathering data in a haphazard way and to do it more properly. This resulted in a first survey of approximately 1,420 and a second one of 2,025 references (van Gemert, 2010 & 2011). Since then, this survey has again been enlarged and revised and a number of errors have been corrected. It contains now approximately 3,050 references. Scope In principle every publication in which molluscs are reported to live or have lived in the Red Sea should be listed in the survey. This means that besides primary literature, i.e. articles in which researchers are reporting their finds for the first time, secondary and tertiary literature, i.e. reviews, monographs, books, etc are to be included too. These publications were written not only by a wide range of authors ranging from amateur shell collectors to professional malacologists but also people interested in the field of archaeology, geology, etc.
