Abstract
Extensive fishing has led to fish stock declines throughout the last decades. While clear stock identification is required for designing management schemes, stock delineation is problematic due to generally low levels of genetic structure in marine species. The development of genomic resources can help to solve this issue. Here, we present the first mitochondrial and nuclear draft genome assemblies of three economically important Mediterranean fishes, the white seabream, the striped red mullet, and the comber. The assemblies are between 613 and 785 Mbp long and contain between 27,222 and 32,375 predicted genes. They were used as references to map Restriction-site Associated DNA markers, which were developed with a single-digest approach. This approach provided between 15,710 and 21,101 Single Nucleotide Polymorphism markers per species. These genomic resources will allow uncovering subtle genetic structure, identifying stocks, assigning catches to populations and assessing connectivity. Furthermore, the annotated genomes will help to characterize adaptive divergence.

Abstract
El estudio de la estructura de las poblaciones y su diferenciación a nivel genético es de gran utilidad para la elaboración de planes de manejo y conservación de especies amenazadas. En este estudio, utilizamos marcadores nucleares y mitocondriales (espaciadores internos de genes ribosomales -ITS y citocromo oxidasa, subunidad I -COI) y métodos de análisis filogenéticos y de clados anidados (NCA), para realizar la primera valoración de la estructura genética del coral naranja Astroides calycularis (Pallas, 1766), una especie amenazada del Mediterráneo, a partir de muestras de 12 localidades a lo largo de su área de distribución. En las localidades situadas en la región más occidental del Mediterráneo se encontró cierta homogeneidad genética, mientras que al comparar estas localidades con las de las cuencas argelina y del mar Tirreno se observó una ligera diferenciación.
