Abstract
Aquaculture industry exposes fish to acute stress events, such as high stocking density, and a link between
stress and higher susceptibility to diseases has been concluded. Several studies have demonstrated
increased stress tolerance of fish treated with probiotics, but the mechanisms involved have not
been elucidated. Shewanella putrefaciens Pdp11 is a strain isolated from healthy gilthead seabream
(Sparus aurata L.) and it is considered as probiotics. The aim of this study was to evaluate the effect of the
dietary administration of this probiotics on the stress tolerance of Solea senegalensis specimens farmed
under high stocking density (PHD) compared to a group fed a commercial diet and farmed under the
same conditions (CHD). In addition, during the experiment, a natural infectious outbreak due to Vibrio
species affected fish farmed under crowding conditions. Changes in the microbiota and histology of
intestine and in the transcription of immune response genes were evaluated at ...
