The endangered giant clam species Tridacna maxima is naturally abundant in some atolls in French Polynesia (FP) and has been the focus of commercial mariculture activities since 2012. Shortly after spat collectors became operational in two atoll lagoons, FP rose to become one of the main exporters of giant clams for the aquarium trade. However, this activity has been threatened recently by a mass clam-bleaching event triggered by the 2015-2016 El Nino. This study reviews the roles that international (Convention on International Trade in Endangered Species of Wild Fauna and Flora) and national regulatory frameworks play in the development of this activity in a small island context, and how they can indirectly promote better science and monitoring in order to inform adaptive management strategies. The links between the nine main groups of stakeholders show the necessary adaptation measures required to mitigate climate-driven mortalities. While this case study remains specific to giant clam farming in FP, general lessons are provided that could help in mitigating economic impacts from climate-related events on other islands. specialized Tridacna maxima climate change mariculture marine policy CITES coral reef POLYNESIE FRANCAISE TUAMOTU 036 021 Environmental Conservation 45 1 30-40 2018 0376-8929 https://www.documentation.ird.fr/hor/fdi:010072424 10.1017/s0376892917000212 0376-8929 [F B010072424] https://www.documentation.ird.fr/hor/fdi:010072424 https://www.documentation.ird.fr/intranet/publi/2018/03/010072424.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-04-03 2023-07-11 fdi:010072424 fre
