Occurrence of Limnoperna fortunei (Mollusca, Mytilidae) in the Uruguay River, municipality of Uruguaiana, western border of Rio Grande do Sul, Brazilian Pampa

Abstract

This paper reports on the occurrence of the golden mussel Limnoperna fortunei (Dunker, 1857) in the natural environment in the city of Uruguaiana, in Rio Grande do Sul. The clusters were detected, photographed and collected on the left bank of the Uruguay River, in Brazilian territory. Two different locations were chosen: the first being near Ponte Internacional Getúlio Vargas-Agustín Justo, a bridge that connects the towns of Uruguaiana/Brazil and Paso de Los Libres/Argentina, and the second near the mouth of the Salso Stream, a tributary of the Uruguay River. The animals were captured and taken to the laboratory where they were identified and stored.
