| Abstract | Thunnus atlanticus is of great commercial importance in Brazil, but infections caused by helminth
parasites can reduce its commercial value. In this paper, 15 species of Digenea and three of
Monogenoidea were recovered from 61 specimens of T. atlanticus collected from the coastal zone
of the State of Rio de Janeiro. Species of the family Didymozoidae were the dominant species,
with highest prevalence and abundance values. The parasites showed the typical aggregated
distribution pattern, except for Nasicola brasiliensis, which had an aleatory distribution pattern.
Prevalence and abundance of Didymosulcus philobranchiarca, Didymocystis lamotheargumedoi
and Didymosulcus wedli and prevalence of Koellikerioides internogastricus were positively
correlated with the total length of the host. The abundance of Coeliotrema thynni was negatively
correlated with total length of the host. New hosts records resulted for four Digenea:
Didymosulcus orbitalis, Didymosulcus wedli, Rhipidocotyle pentagonum and Lecithochirium
microstomum, and one Monogenoidea: Nasicola brasiliensis. | pt_BR |
