PRIMEIRO REGISTRO DE Cymothoa sp. FABRICIUS, 1793 (ISOPODA: CYMOTHOIDAE) PARASITANDO O PEIXE DE QUATRO OLHOS, Anableps anableps (CYPRINODONTIFORMES: ANABLEPIDAE), NA COSTA NORTE BRASILEIRA

Abstract

This study presents the first record of the occurrence of Cymothoa Fabricius, 1793 in northern Brazil, as well as in four-eyed fish Anableps anableps . The research was conducted in the Curuca estuary, in northern Brazil, where 158 specimens of A. anableps were collected, with nine Cymothoa specimens being found on nine different fish. These isopods were identified by sequencing the mitochondrial Cytochrome Oxidase I gene. The prevalence of the parasite (4.43 %) in A. anableps was extremely low and Cymothoa sp. specimens were found primarily in the gills of the host fish. Keywords: Amazon; Isopoda; Crustaceans; Four-Eyed Fish; Anablepidae.
