Monogenoidea en Serrasalmus rhombeus (Linnaeus, 1766) de la Cuenca Amazónica Boliviana

Abstract

The present work analyse monogenoids parasite diversity as one independent character, hoping they can characterize the white piranha (Serrasalmus rhombeus) populations by its high specificity. Study was carried out in four sub-basins (Iténez, Beni, Madre de Dios e Ichilo) from the Bolivian Amazon Basin. A total of 1135 parasites were obtained, belonging to six genera and 11 species: Anacanthorus jegui, A. amazonicus, A. rondonensis, A. gravihamulatus, A. sciponophallus, Anacanthorus sp.1, Anacanthorus sp.2, Anacanthorus sp.3; Notothecium deleastum, N. deleastoideum, Notozothecium teinodendrum; Mymarothecium galeolum; Anphithecium diclonophallum y Enallothecium aegidatum. The high parasite diversity could be related to one complex of populations or species of Serrasalmus rhombeus existent or extintic.
