Abstract
In the present study, a total of 31 specimens of pontic shad, Alosa immaculata Bennet, 1835 (Pisces: Clupaeidae) caught in the Black Sea coasts near Sinop, Turkey in 2010 were investigated for their parasite fauna. Four parasite species were identified: Mazocraes alosae (Herman, 1782), Pronoprymna ventricosa (Rudolphi, 1891), Lecithaster confusus Odhner, 1905 and Hysterothylacium aduncum (Rudolphi, 1802). H. aduncum was the core species with infection prevalence of 96.7% and mean intensity value of 97.1 ± 18.1 parasites per infected fish, followed by M. alosae (61.3% and 3.2 ± 0.5), P. ventricosa (35.5% and ± 12.5) and L. confusus (29% and 8.2 ± 2.8), respectively. In the present study, Mazocraes alosae, Pronoprymna ventricosa and Lecithaster confusus are reported from pontic shad off Turkish coasts of the Black Sea for the first time.
