Comment on “Multiple tools to investigate the origin of the exotic species Chinook salmon Oncorhynchus tshawytscha (Walbaum, 1792) (Salmonidae) in the world's largest chocked coastal lagoon (Gonçalves et al., 2025)”

Gowert et al. (2025) reported the presence of an adult female Chinooksalmon (Oncorhynchus tshawytscha) in the Patos Lagoon, Brazil.The authors presented their findings as ‘the first scientific record’ ofnon-native Chinook salmon in this location, based on a combinationof techniques that confirmed species identity (DNA barcoding) and itsanadromous life history (stable isotopes). However, Gowert et al.(2025) discounted the early report by Figueroa-Muñoz et al. (2023),which previously documented the presence of this salmonid in thesame location as the northernmost record of the species in the AtlanticOcean. Gowert et al. (2025) erroneously suggested that Figueroa-Muñoz et al. (2023) likely confused the Patos Lagoon in Brazil with ahomonymous system in Chile.
