Crustáceos decápodos de la cuenca del Río Sinú, Córdoba, Colombia

Abstract

To review the composition, abundance and distribution of decapod crustaceans in the Sinu river basin, Department of Cordoba (Colombia) eight locations were studied: four on the Sinu River and four in the Low Complex Swampy Sinu. For that, six samplings between April 2005 and May 2006 were made. In total 458 decapod crustaceans were recorded distributed into three families, six genus and eight species. The family best represented was Trichodactylidae with four genus and four species, followed by Palaemonidae with one genus and three species, while family Atyidae recorded only one species. Species such as Macrobrachium carcinus and M. acanthurus presented the wider range of distribution for both the Sinu River as the Low Complex Swampy Sinu. Among the identified species Atya crassa in the Sinu River and Trichodactylus quinquedentatus in the Low Complex Swampy Sinu are new records for the Department of Cordoba.
