We present new ichthyo-archaeological evidence about the native ichthyofauna and ancient fishing practices of the human populations that inhabited Nahuel Huapi lake landscape during the late Holocene. The analysis of fish remains found at the PT1 site on Isla Victoria (Nahuel Huapi National Park, Patagonia, Argentina) allowed us to identify the lacustrine assemblage of native species that included at least 5 species. Our findings also indicate temporal variations in the frequency and diversity of species exploited at the site. Likewise, these data provide valuable insights on native landscapes, specifically in relation to aspects of biodiversity prior to the introduction of exotic species more than 100 years ago. Finally, we discuss significance of the novel and until now underappreciated records in understanding the historical role of fish in sustaining the human populations that inhabited the region, and in identifying processes of change and transformations that occurred in aquatic landscapes over time.
