Abstract

Fish aquaculture is considered to be one of the most sustainable sources of protein for humans. Many different species are cultured worldwide, but among them, marine flatfishes comprise a group of teleosts of high commercial interest because of their highly prized white flesh. However, the aquaculture of these fishes is seriously hampered by the scarce knowledge on their biology. In recent years, various experimental ‘omics’ approaches have been applied to farmed flatfishes to increment the genomic resources available. These tools are beginning to identify genetic markers associated with traits of commercial interest, and to unravel the molecular basis of different physiological processes. This article summarizes recent advances in flatfish genomics research in Europe. We focus on the new generation sequencing technologies, which can produce a massive amount of DNA sequencing data, and discuss their potentials and applications for de novo genome sequencing and transcriptome analysis. The relevance of these methods in nutrigenomics and foodomics approaches for the production of healthy animals, as well as high quality and safety products for the consumer, is also briefly discussed.
