Occurrence of the swimbladder parasite Anguillicola crassus (Nematoda, Dracunculoidea) in European eels (Anguilla anguilla) in Ceyhan River, Turkey

2002 yılında Ceyhan Nehri (Adana, Türkiye)'nden avlanan Avrupa yılan balıkları {Anguilla anguilla), yüzme kesesi nematodunun varlığı yönünden incelenmişlerdir. İncelenen 64 balığın 50'sinde, yüzme kesesi paraziti Anguillicola crassus infeksiyonuna rastlanılmıştır. Temmuz ve Kasım örneklerindeki; parazit sayıları, prevalans (%) aralığı ve ortalama parazit yoğunluğu değerleri, sırasıyla; 93, % 82,86, 2-7, 3,31 ± 1,32 ve 56, % 72,41,1 -5, 3,20 ± 1,30 olarak bulunmuştur. Infekte balıklarının iç organlarında histopatolojik bir olguya rastlanmamıştır.

Ceyhan Nehri (Türkiye) Avrupa yılan balıklarında (Anguilla anguilla) rastlanılan yüzme kesesi paraziti, Anguilicola crassus (Nematoda, Dracunculoidea)

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.
