Drivers of richness and abundance of parasites of fishes from an intermittent river before and after an interbasin water transfer in the Brazilian semi-arid region.

This study examined the metrics of the macroparasite community in fishes from the Jaguaribe River basin, state of Ceará, before and after receiving water from the São Francisco River in Northeastern Brazil. This research assessed the association of environmental factors (water parameters) and the traits of 30 fish species on the parasite richness and abundance across space (river course) and time (seasons, pre- and post-transposition periods). Generalized linear models reveal associations between parasite metrics and host traits, water parameters, and river sub-basin.

Metazoan parasites of white mullet Mugil curema Valenciennes, 1836 (Mugiliformes: Mugilidae) and new records of occurrence in the western Atlantic, Brazil.

Mugil curema is a pelagic fish species and it is considered the most common species of the Mugilidae family on the Brazilian coast. The objective of this study was to compile the existing information on the metazoan parasites of this host, as well as including new records from specimens captured in the Cabedelo city, state of Paraíba, Brazil. In the present study, we listed 81 taxa belonging to ten groups previously recorded for the host M.
