Molecular identification and phylogenetic analysis of Siluriformes from the Paraguay River basin, Brazil.

The objective of this study was to identify, through the DNA barcode, fishable Siluriformes which were collected from the Paraguay River basin in Pantanal. It was analyzed for genetic distance calculation using the Kimura-two-model parameters and the dendrogram was builtusing the Neighbour-Joining algorithm. The average genetic distance within species, genus and families were 0.
