New records of introduced fish in the Desaguadero River Basin in central-western Argentina

Abstract

Three new records of introduced fish in San Juan province, Argentina are reported: two Siluriformes, Hypostomus commersoni and Pimelodella laticeps, and one Cyprinodontiform, namely Gambusia affinis. We register the presence of H. commersoni and G. affinis in the Desaguadero River Basin for the first time and extend the distribution of P. laticeps within the basin.

Keywords: distribution, Hypostomus commersoni, Pimelodella laticeps, Gambusia affinis, transplanted species, exotic species.
