Abstract

The genetic similarity of six species from the Pimelodidae family (Osteichthyes, Siluriformes), collected at four sites in the Tibagi River basin, was analyzed using RAPD. RAPD comparative analysis was carried out to observe the degree of genetic similarity among the six species of Pimelodidae. The dendrogram obtained by analysis of the comparative RAPD profiles clearly showed that the individuals investigated from each species clustered together, that is, there was a defined separation among the six species. Two clusters also separated distinctly, one formed by the P. maculatus, P. cf. absconditus, I. labrosus and P. pirinampu (Pimelodinae subfamily) species and the other by the P. aff. avanhandavae and Pimelodella aff. meeki (Heptapterinae subfamily) species. The genetic similarity among these groupings was 0.084.
