  abstract = {{V}ibrio species have been associated with recurrent mass mortalities of juvenile oysters {C}rassostrea gigas threatening oyster farming worldwide. {H}owever, knowledge of the ecology of pathogens in affected oyster farming areas remains scarce. {S}pecifically, there are no data regarding (i) the environmental reservoirs of {V}ibrio populations pathogenic to oysters, (ii) the environmental factors favoring their transmission, and (iii) the influence of oyster farming on the persistence of those pathogens. {T}his knowledge gap limits our capacity to predict and mitigate disease occurrence. {T}o address these issues, we monitored {V}ibrio species potentially pathogenic to {C}. gigas in 2013 and 2014 in the {T}hau {L}agoon, a major oyster farming region in the coastal {F}rench {M}editerranean. {S}ampling stations were chosen inside and outside oyster farms. {A}bundance and composition of phyto-, microzoo-, and mesozooplankton communities were measured monthly. {T}he spatial and temporal dynamics of plankton and {V}ibrio species were compared, and positive correlations between plankton species and vibrios were verified by q{PCR} on isolated specimens of plankton. {V}ibrio crassostreae was present in the water column over both years, whereas {V}ibrio tasmaniensis was mostly found in 2013 and {V}ibrio aestuarianus was never detected. {M}oreover, {V}. tasmaniensis and {V}. crassostreae were found both as free-living or plankton-attached vibrios 1 month after spring mortalities of the oyster juveniles. {O}verall, {V}. crassostreae was associated with temperature and plankton composition, whereas {V}. tasmaniensis correlated with plankton composition only. {T}he abundance of {V}ibrio species in the water column was similar inside and outside oyster farms, suggesting important spatial dispersion of pathogens in surrounding areas. {R}emarkably, a major increase in {V}. tasmaniensis and {V}. crassostreae was measured in the sediment of oyster farms during cold months. {T}hus, a winter reservoir of pathogenic vibrios could contribute to their ecology in this {M}editerranean shellfish farming ecosystem.},
