  abstract = {{S}tudying the larval dispersal of bottom-dwelling species is necessary to understand their population dynamics and optimize their management. {T}he black-lip pearl oyster ({P}inctada margaritifera) is cultured extensively to produce black pearls, especially in {F}rench {P}olynesia's atoll lagoons. {T}his aquaculture relies on spat collection, a process that can be optimized by understanding which factors influence larval dispersal. {H}ere, we investigate the sensitivity of {P}. margaritifera larval dispersal kernel to both physical and biological factors in the lagoon of {A}he atoll. {S}pecifically, using a validated 3{D} larval dispersal model, the variability of lagoon-scale connectivity is investigated against wind forcing, depth and location of larval release, destination location, vertical swimming behavior and pelagic larval duration ({PLD}) factors. {T}he potential connectivity was spatially weighted according to both the natural and cultivated broodstock densities to provide a realistic view of connectivity. {W}e found that the mean pattern of potential connectivity was driven by the southwest and northeast main barotropic circulation structures, with high retention levels in both. {D}estination locations, spawning sites and {PLD} were the main drivers of potential connectivity, explaining respectively 26%, 59% and 5% of the variance. {D}ifferences between potential and realistic connectivity showed the significant contribution of the pearl oyster broodstock location to its own dynamics. {R}ealistic connectivity showed larger larval supply in the western destination locations, which are preferentially used by farmers for spat collection. {I}n addition, larval supply in the same sectors was enhanced during summer wind conditions. {T}hese results provide new cues to understanding the dynamics of bottom-dwelling populations in atoll lagoons, and show how to take advantage of numerical models for pearl oyster management.},
