[Infestation of Benedenia sciaenae van Beneden, 1856 (Monogenea: Capsalidae) of cultured meagre (Argyrosomus regius)].

This study was carried out to investigate the reasons for scale loss, hemorrhage and local lesions on the skin of cultured meagre (Argyrosomus regius Asso, 1801), that are an alternative to the sea bass and sea bream. All of the 40 fish examined (5.63 +/- 0.89 kg in weight, 91.3 +/- 3.6 cm in length) had parasites on the area with lesions and the parasite was identified as Benedenia sciaenae van Beneden, 1856 (Monogenea: Capsalidae) after examination. The dimensions of the parasite were measured and drawn. This is the first report of B. sciaenae in Turkey.
