Occurrence of the Swimbladder Parasite Anguillicola crassus (Nematoda, Dracunculoidea) in European Eels (Anguilla anguilla) in Ceyhan River, Turkey

European eels (Anguilla anguilla), collected from the Ceyhan River (Adana, Turkey) in 2002, were examined in terms of the presence of swimbladder nematoda. The existence of infection with Anguillicola crassus, a pathogenic swimbladder parasite, was identified in 50 out of 64 specimens. The total number of parasites, prevalence (%), parasite abundance and mean intensity of parasite values of July and November samples were 93, 82.86%, 2-7, 3.31 ± 1.32 and 56, 72.41%, 1-5, 3.20 ± 1.30, respectively. There was no significant histopathological destruction in the internal organs of the infected eels.
