The feasibility of using data from the OLI sensor onboard Landsat-8 satellite to determine chlorophyll a concentrations (Chla) in a deep atoll, Ahe, was then assessed over the 2013-2021 period using 153 images. Validations with in situ observations were satisfactory, while seasonal and spatial patterns in Chla were evidenced within the lagoon. Then, a bioenergetic modelling exercise was undertaken to estimate oyster life-history traits when exposed to the retrieved Chla. The outputs provide spatio-temporal variations in pelagic larval duration (11.1 to 30.6 days), time to reach commercial size (18.8 to 45.3 months) and reproductive outputs (0.5 to 1.7 event year(-1)). This first study shows the potential of using remote sensing to monitor the trophic status of deep pearl farming lagoons and help aquaculture management. specialized Landsat-8, time series Plankton Aquaculture DEB model Pinctada margaritifera PACIFIQUE POLYNESIE FRANCAISE TUAMOTU ARCHIPEL 040 126 036 020 181 113863 [13 p.] 2022 0025-326X https://www.documentation.ird.fr/hor/fdi:010085892 10.1016/j.marpolbul.2022.113863 0025-326X [F B010085892] https://www.documentation.ird.fr/hor/fdi:010085892 https://www.documentation.ird.fr/intranet/publi/2022-09/010085892.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-09-28 2025-02-24 fdi:010085892 fre
