First record of Centropomus undecimalis (Bloch, 1792) (Perciformes, Centropomidae), Common Snook, in the Patos Lagoon estuary, in southern Brazil

Abstract

We report the first record of Centropomus undecimalis (Bloch, 1792), Common Snook, in the Patos Lagoon estuary (32°S), Brazil. Two specimens were caught in April and May 2021 as bycatch in the fyke nets fish-ery for shrimp. Centropomus undecimalis was previously known to occur south to 29° S. We hypothesize that the intensification of the warm Brazilian Current has being promoted an expansion southward of this fish species along the Brazilian coast.
