The spatial and temporaldynamics of Vibrio harveyi were studied on a European seabass farm in northern France during sevenmonths of 2022. Concrete specimens were suspended and water was pumped from different depths(0.3 m, 2.15 m and 4 m deep), providing insights into the biofilm and planktonic V. harveyi dynamics.The abundances of V. harveyi, in the biofilm and free-living forms, were positively correlated. Thewater parameters revealed seasonal fluctuations in temperature, pH, and salinity, with no significantdifferences observed across the water column. Quantification of V. harveyi revealed no significantdifferences between depths, but seasonality, with peak abundances observed in August, correlatedwith temperature increases. Principal component analysis identified temperature as a primary driver,but also additional parameters, such as salinity and pH. Vibriosis occurred during the samplingperiod, providing valuable insights into the conditions before, during, and after the outbreaks. Thisstudy underscores the importance of understanding V. harveyi behaviour in aquaculture, particularlyin the context of global warming, for effective disease management and sustainable practices.
