FAUNA PARAGUAY LIST OF THE FISH OF PARAGUAY

The following is a tentative list of the 395 fish species documented for Paraguay based on the Guyra Paraguay Faunal Database and changes proposed by ichthyologist Hector Vera Alcaraz whom we thank for his support and professional advice. The scientific and English names are given (where they exist). Numbers in brackets after the order and family names refer to the number of species recorded in Paraguay. Names of descriptors and dates of description are taken from the Fish Base website. Please note that no significance should be read into the brackets surrounding the descriptors.
