Metazoan parasites of Plagioscion squamosissimus, an invasive species in the Tietê River, São Paulo, Brazil

Abstract: This study focused on the characterization and analysis of communities and infra-communities of metazoan parasites of Plagioscion squamosissimus caught in Promissão Reservoir in the Tietê River in Borborema (21°39′58"S, 49°8′49"W), state of São Paulo, Brazil. Fifty adult specimens caught by professional fishermen in March 2015 were necropsied. The fish presented an average standard length of 25.2 ± 2.2 cm and average weight of 328.82 ± 89.03 g. A total of 5,227 specimens of metazoan parasites were collected: 2… Show more

“…The infection levels of monogeneans in P. squamosissimus and P. surinamensis were similar, since they are congeneric species of hosts inhabiting the same environment. However, in P. squamosissimus from the Tietê River, where it was introduced, there was infection only by D. piscinarius (Lapera et al, 2017) and the parasitism levels were higher than in P. squamosissimus and P. surinamensis of the current study. Lapera et al (2017) showed that infections by D. piscinarius cause lesions in the gills of P. squamosissimus, because this monogenean species can be potentially harmful to hosts.…”

“…In fish populations, sometimes the parasite abundance is correlated with body size of the host population, but this correlation may also be weak or non-existent due to several factors, for example, small variation in host size, small sampling, etc. (Lizama et al, 2008;Hoshino & Tavares-Dias, 2014;Tavares-Dias et al, 2014Neves et al, 2016;Oliveira & Tavares-Dias, 2016;Lapera et al, 2017;Gallegos-Navarro et al, 2018). In M. lippincottianus from the Matapi River, the abundance of A. jegui had a weak positive correlation with body weight of this host.…”

“…Feltran et al (2004), também relataram prevalência similar no Reservatório da Usina Hidrelétrica de Nova Ponte, no município de Perdizes/ MG, encontrando parasitos em 85% dos peixes analisados. Entretanto, Lapera et al (2017), encontraram resultados superiores no Reservatório de Promissão, Rio Tietê, Estado de São Paulo, relatando a prevalência de 100% de hospedeiros infectados.…”
