MORPHOLOGICAL AND HISTOPATHOLOGICAL ASPECT OF PARASITES OF THE CLASS MYXOZOA AND PHYLUM APICOMPLEXA IN Cichla monoculus (Spix & Agassis, 1831) FROM THE MUNICIPALITY OF PRACUÚBA-AMAPÁ, BRAZIL

The Brazilian Amazon is privileged to have the largest freshwater basin in the world with a diversity of fish species. The state of Amapá has five sectors for fishing activities in the region: the maritime plain on the north coast, the urban and port area located in Macapá and Santana, the upper estuary region that begins at the mouth of the Matapi River up to the border with the state of Pará and the lakes region where the municipality of Pracuúba is located. The Tucunaré (Cichla sp) is a commercially important Amazonian fish, and the Cichla monoculus is a species with a wide geographical distribution that is widely consumed by the riverside population. Fish are vulnerable to different parasites, including myxosporids and coccids from the Apicomplexa phylum. The aim of this study was to investigate eukaryotic microparasites of the class Mixozoa and phylum Apicomplexa in Cichla monoculus from the municipality of Pracuúba-Amapá, Brazil. In preliminary results, the Tucunarés (Cichla sp.) of the species analyzed have shown parasitism and the results of other analyses could lead to the description of new species and a systematic understanding of their taxonomic and phylogenetic aspects.
