After the economic decline that characterized the last decade, concerns recently rose about discarded installations and materials that supported aquaculture practices and by facilities abandoned after they had to close their activities. In May 2013, a first inventory of the type and amount of pearl farms derelict gear (PFDG) was achieved on 47 sites in Ahe lagoon. Surveys were conducted within and outside the boundaries of aquaculture concessions. Twenty types of PFDG littered the lagoon floor and the water column. The most impacted areas were near abandoned grafting houses with up to nine types of PFDG. Forty-five percent of the sites were impacted, including outside concessions. While management authorities are fully aware of the problem, this first assessment is a wake-up call to stimulate the cleaning of lagoons, enhance awareness among farmers, and identify potential ecological consequences on lagoon ecosystems. specialized Aquaculture Marine debris Pearl farm derelict gear Atoll POLYNESIE FRANCAISE 040 038 83 1 224-230 2014 0025-326X https://www.documentation.ird.fr/hor/fdi:010062341 10.1016/j.marpolbul.2014.03.048 0025-326X [F B010062341] https://www.documentation.ird.fr/hor/fdi:010062341 https://www.documentation.ird.fr/intranet/publi/2014/08/010062341.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-09-09 2017-08-23 fdi:010062341 fre
