  abstract = {{T}his study reports the first measurements of nitrogen uptake and new data on carbon fixation ({N}-15/{C}-13 incorporation) for two size-fractionated phytoplankton (<2 mu m and >2 mu m), on organic matter, and phytoplankton stocks in {A}he lagoon. {D}ata were collected between {N}ovember and {D}ecember 2017, during the hot season with prevailing trade winds. {A}mmonium and nitrate uptake data (7.58 to 39.81 and 1.80 to 21.43 mu mol {N} m(-3) h(-1), respectively) suggest a rapid turn-over of {N}-nutrients in the water column and show that primary production was largely sustained by recycled nitrogen providing 68% of the pelagic {N} demand. {T}hese results highlight the spatial heterogeneity of the measured processes linked to the local hydrodynamics, exhibiting higher regenerated production in the more exploited southwestern part of the lagoon and a higher proportion of new production in the north. {I}ntense nutrient recycling appears to promote nanophytoplankton production which is critical for pearl oyster growth.},
