文摘

We coupled a bioenergetics growth model (DEB) with A 3D lagrangian transport model. Larval dispersal and recruitment were simulated in two real contrasted conditions. Spat supply and connectivity pattern were mainly affected by trophic heterogeneity. Despite an unbalanced sex-ratio the reared broodstock mostly supplied spatfall. We offer key clues for pearl oyster population management in atoll lagoons.
