  abstract = {{T}he black-lipped pearl oyster ({P}inctada margaritifera) is extensively farmed in {F}rench {P}olynesia to produce black pearls. {F}or a sustainable management of marine resources, studying interactions between organisms and environment, and the associated factors and processes that will impact their life cycle and thus modulate population dynamics is a major research priority. {H}ere, we describe black-lipped pearl oyster energy acquisition and use, and its control by temperature and food concentration within the {D}ynamic {E}nergy {B}udget ({DEB}) theory framework. {T}he model parametrization was based on literature data and a specific laboratory experiment. {M}odel validation was carried out thanks to historical in-situ datasets and a dedicated field survey. {T}hree theoretical environmental scenarios were built to investigate the response of the pearl oyster to environmental variations. {W}e successfully modeled a wide range of life-stage-specific traits and processes, especially the delayed acceleration of growth after settlement. {A}pplying the model on field data collected at three different culture sites required only one free-fitted parameter, the half saturation coefficient {X}-k, which controls how ingestion depends on food density. {X}-k integrates all variations linked to the trophic environment. {A}nalysis of the kinetics of energy fluxes under theoretical environmental scenarios suggests that temperature variations induce seasonality of reproduction in a species thought to spawn opportunistically throughout the whole year. {T}he major influence of food concentration fluctuations on growth rate and reproductive effort is highlighted. {T}he model showed the lower performances associated with recovery time between food-rich and starvation periods. {T}he implications of these findings in the context of black pearl farming in a changing environment are discussed.},
