Fish genomics has become an essential tool to explore the genetic basis of biological processes, such as biodiversity, evolution, and adaptation, as well as for direct applications in conservation, aquaculture, and fisheries management. Argentina, home to more than 1,100 fish species and diverse aquatic ecosystems, holds enormous potential for genomic research. Although historically underrepresented in global databases, recent progress (including genome sequencing of commercially and ecologically important species) signals growing momentum in the field. This note provides an overview of the current state of fish genomics in Argentina, highlights notable contributions, and underscores the need for high-quality genome assemblies, national coordination, and broader taxonomic coverage to ensure that the country’s biodiversity is adequately represented and preserved.
