Fishes of Cuniã Lake, Madeira River Basin, Brazil

This study presents an inventory of the ichthyofauna of Cuniã Lake, situated in the floodplain of the Madeira River in Rondônia State, Brazil. A total of 11,949 specimens representing eight orders, 34 families, and 189 species were sampled with gill, seine, and hand nets during the dry and wet seasons between 2008 and 2012. Most of the species recorded in Cuniã Lake are commonly found in other locations in the central Amazonian floodplains, although some are rare in collections (e.g. Acestrorhynchus minimus, Triportheus culter, Oxybrycon parvulus, Tyttocharax madeirae, Trachycorystes trachycorystes and Scorpiodoras lyophisus) or represent new distributional records
