  abstract = {{I}n {F}rench {P}olynesia, the pearl oyster {P}inctada margaritifera has allowed black pearl production since four decades. {T}he production remains dependent on spat collections in atoll lagoons. {T}hrough their reproduction, the oysters of the natural stock are contributors of spats, and possibly the only contributor. {A}fter an assessment in 2013, natural stocks of {T}akaroa and {A}he atolls were revisited in 2022 and 2024 respectively. {R}esults show a sharp decrease of the densities at almost all field sites, with average lagoon-wide losses by factors of 2.35 and 8.87 for {A}he and {T}akaroa respectively. {T}akaroa was impacted in 2013-2014 by a massive harmful phytoplanktonic bloom and the decrease was expected, but the population size structure shows recruitment, providing hope for farmers. {C}onversely, the reason for {A}he's population decline remains unclear. {L}ikely suspects are increased periods of high temperature and predation that affect oysters at their different life stages and impact recruitment and survival.},
