Fish parasites are an important part of aquatic biodiversity and knowing these species and their interactions with their hosts helps in monitoring the aquatic biota. The present study investigated the ectoparasite crustacean fauna of ten fish species from the upper Araguari River, in the state of Amapá, northern Brazil. A total of 508 fish were collected and analyzed from July to November 2014, of which 82.

- The study examined how two types of parasites, Ergasilus sp. and Therodamas longicollum, inhabit the gills of the fish Leporinus fasciatus from the Amazon.
- About 35% of the fish had gills infested with these parasites, with Ergasilus sp. favoring attachment to the first arch of the gills, while T. longicollum preferred the third section.
- A negative correlation was found between the abundance of the two parasites, indicating that they compete for space on the gills without overlapping their specific locations.
Migratory species are the most important commercial fishes in the Amazon. They are also now the most threatened directly by some combination of overfishing, floodplain deforestation, and dam construction. Limited governmental monitoring and implemented regulations impede adequate management of the fisheries at adequate scale.
