This dataset contains georeferenced occurrence records of the Yellowfin Tuna (Thunnus albacares) from 1950 to 2025, obtained globally from the Global Biodiversity Information Facility (GBIF). The dataset was filtered to include presence-only records with valid geographic coordinates and year, and duplicate coordinates were removed.
