First record of metazoan parasites of hybrids between the genera Colossoma and Piaractus in natural environments

The practice of hybridization is carried out globally in fish farms. Here, we present the first record of the parasitic fauna of hybrids among genus Colossoma and Piaractus in natural environments. We identified a total of 48 hybrids, nine F1 hybrids (nuclear DNA from both species present in the cro...

Description
Summary:	The practice of hybridization is carried out globally in fish farms. Here, we present the first record of the parasitic fauna of hybrids among genus Colossoma and Piaractus in natural environments. We identified a total of 48 hybrids, nine F1 hybrids (nuclear DNA from both species present in the cross) and 38 advanced hybrids (nuclear DNA from one species), both from crosses between Piaractus brachypomus and Piaractus mesopotamicus , and one F1 “tambacu” corresponding to cross between Colossoma macropomum and Piaractus mesopotamicus . This is the first record of Anacanthorus penilabiatus , Anacanthorus toledoensis , Mymarothecium viatorum , Mymarothecium ianwhittington , Haementeria sp., Dadaytrema oxycephala , Rondonia rondoni , and Echinorhynchus gomesi parasitizing hybrids collected in a natural environment. With this, we expand knowledge about the diversity of fish and parasites in the upper Paraná River and warn about the risk that fish escapes can cause in the basin.
