RNA sequencing of liver and muscle tissue from three geneticcally distinct populations of European seabass (Dicentrarchus labrax) for the EpiFishNess project, 2024

We generated RNA sequencing data from liver and muscle tissues of European seabass (Dicentrarchus labrax) at 1 year old (adult) to investigate population-specific gene expression patterns among Atlantic (AT), Western Mediterranean (WM), and Eastern Mediterranean (EM) populations. Using a common-garden experimental design, this dataset aims to characterize intrinsic regulatory differences while minimizing environmental effects. The data provide a resource to study how gene expression contributes to population divergence and phenotypic variation.
