  abstract = {{I}n the context of increasing demand for environmental recovery, aquatic systems may face the challenge of evolving under oligotrophication. {T}his is the case in {M}editerranean lagoons, in particular the shellfish-farmed {T}hau lagoon in {F}rance, where we studied recruitment of the {P}acific oyster {C}rassostrea gigas. {O}yster spat and environmental parameters were monitored at several sampling sites for 3 yr (2012 to 2014) using an original method with a temporal overlap deployment of collectors to study pre- and post-settlement processes and to identify the best conditions for recruitment. {C}ontrary to the 'no {P}acific oyster reproduction' paradigm in {M}editerranean lagoons, our study showed that recruitment of this introduced species is possible in the {T}hau lagoon at levels comparable to those in other traditional {F}rench breeding basins. {W}e identified a favorable environmental window for recruitment characterized by high water temperature (> 26.5 degrees {C}) and high nanophytoplankton and {C}haetoceros spp. abundances (> 4.3 x 10(6) and 345 x 103 cells l(-1), respectively). {I}n these favorable conditions, we hypothesize that the ecosystem functions as an autotrophic system, in contrast to the heterotrophic system that characterizes unfavorable conditions. {U}nder heterotrophic conditions, high abundances of mixotrophic and heterotrophic organisms (ciliates and dinoflagellates) limited the metamorphosis of {C}. gigas larvae, leading to poor recruitment. {T}his study provides new knowledge on the reproduction of the {P}acific oyster in a {M}editerranean lagoon under warming and oligotrophication. {T}he shellfish industry will profit from the discovery of spatfields to developnewnursery practices that are eco-friendly and limit risks of transfers with other spatfall areas.},
