    Summary
    The gilthead seabream is an important cultivated species in the Mediterranean area. A major problem for the gilthead seabream aquaculture sector derives from the high frequency of phenotypic abnormalities, including discolorations. In this study, we applied a whole‐genome resequencing approach to identify a genomic region affecting a pigmentation defect that occurred in a cultivated S. aurata population. Two equimolar DNA pools were constructed using DNA extracted from 30 normally coloured and 21 non‐pigmented fish collected among the offspring of the same broodstock nucleus...
