Range Extension of the Popeye Catalufa (Pristigenys serrula, Gilbert 1891) to Central Chile During the “El Niño” Southern Oscillation (ENSO) 2023–2024

Abstract

We report the presence of Pristigenys serrula Gilbert 1891 off Zapallar (−32.568253, −71.464225), central Chile, during the ENSO 2023–2024 event. Morphology and a partial fragment of the mitochondrial markers cytochrome oxidase 1 (COX1) and 16S rDNA identified one specimen fished by artisanal fishermen. This report extends the known southern range limit of P. serrula by 9° of latitude (~1000 km) to central Chile (−32°) during strong negative ENSO conditions.
