Gut microbiome as an important tool for the evaluation of cultured fish performance

The study of the composition of the gilthead sea bream gut microbiome is becoming a relevant item in the “omics” technological offer of IATS Nutrigenomics and Fish Pathology groups. Along 2021, this tool has been of importance to assess the effects of probiotics, feed additives and alternative protein sources in aquaculture feeds. This has resulted in four Open Access publications (1, 2, 3, 4) in the framework of European (GAIN, AQUAEXCEL2020) and national (BreamAquaINTECH) projects. These notable results have been highlighted in a CSIC Valencia delegation press release.
