AB The aim of this studywas to determine the in£uence ofthe feeding regimes in Senegalese sole (Solea senegalensis)culturedunder extensive, semi-extensive and intensiveproduction systems.Atotal of 254 bacterial isolatesfrom guts of ¢sh cultured under di¡erent productionsystems and feeding regimes were tested. Biochemicaltests and genetic analyses based on the 16S rDNA sequenceanalysis were conduced to identify bacterialstrains.Vibrio species were the most represented taxonomicgroup in the culturable microbiota of S. senegalensisguts tested. Particularly,Vibrio ichthyoenteri wasthe most frequently isolatedVibrio species. Comparisonamong diets showed a signi¢cant reduction (Po0.05)in vibrio percentages and a higher occurrence of Shewanellaspecies in Senegalese soles fed polychaeta. Inaddition, a major in£uence of environmental temperatureon microbiota composition was detected. Coldtemperatures brought about a change in the percentagesofVibrio species and a higher representation of a-Proteobacteria in both outdoor systems (extensive andsemi-extensive).The signi¢cant di¡erences between intestinalbacterial composition in Senegalese soles fedcommercial diets and natural preys (polychaeta) revealthe necessity to develop speci¢c optimized diets for theintensive rearing of this ¢sh species.
