Figure 1

Atlantic bluefin tuna (ABFT) larvae were collected with plankton nets during 2014 in two main spawning areas for Thunnus thynnus: (A) the Gulf of Mexico (GOM) and (B) the Mediterranean Sea (MED). Explored stations are indicated with crosses, positive stations for ABFT are indicated with empty circles, and filled circles indicate stations where larvae collected were genotyped. In the GOM larvae were collected in two areas, west and east of 90°W. In the MED larvae were collected in the waters surrounding the Balearic Islands.
