Abstract

RESUMO THE SPECIES OF COPEPODA (CRUSTACEA: ERGASILIDAE) PARASITES OF GILL FILAMENTS OF Potamorhina latior (Spix & Agassiz, 1829) (CHARACIFORMES: CURIMATIDAE) OF CENTRAL AMAZON FLOODPLAIN LAKES, BRAZIL ABSTRACTThree species of Copepoda were collected in the gills of Potamorhina latior from six floodplain lakes, five from Solimões River and one from the Purus River, Amazonas State: Amplexibranchius bryconis; Ergasilus jaraquensis and Miracetyma etimaruya. Potamorhina latior is a new host for A. bryconis and E. jaraquensis and the second record for M. etimaruya. Amplexibranchius bryconis was the dominant species (77%) and with higher rates of parasites. The highest prevalence occurred in the dry season. There was no significant (p> 0.05) negative correlation between the length of P. latior and abundance. There was expanded geographical distribution of M. etimaruya to the Solimões River.

Diversity and similarity in parasitic infracommunities of Mylossoma aureum and Mylossoma duriventre (Characiformes, Serrasalmidae) from the Middle Madeira River Basin, Southern Amazonas, Brazil

“…Gomes (2018) also identified these copepods in M. duriventre collected in floodplain lakes in the Solimões River. Other studies involving different hosts have also reported parasitism by A. bryconis in fish from the floodplains of the Negro, Solimões and Purus rivers (Dumbo, 2014;Morey et al, 2015;Morey, 2017;Vital, 2018).…”
