Zooming into the evolution of Atlantic Bluefin tuna (Thunnus thynnus) using high-throughput sequencing: towards a phylogenomics and population dynamics informed management

Abstract

Existence of contemporary unidirectional trans-Atlantic gene flow, stablishment of a recently originated mixed spawning area, and estimation of stock mixing proportions on feeding grounds in the Atlantic bluefin tuna (Thunnus thynnus), all relevant for the conservation and management of the species, are revealed from the study of the phylogenetic relationships within the genus Thunnus and the species¿ population structure using Single Nucleotide Polymorphisms (SNPs) discovered and genotyped through high-throughput sequencing.
