Trematodes in fishes of the genus Diplodus (Teleostei, Sparidae) from Bizerte Lagoon (Northern coast of Tunisia).

摘要

Eleven species of trematodes were found in the digestive tract of 223 sparid fishes of the genus Diplodus (D. annularis, D. puntazzo, D. sargus and D. vulgaris) sampled from Bizerte Lagoon (NE coast of Tunisia). D. annularis and D. vulgaris were infected mainly by Macvicaria crassigula and the trematode fauna of D. sargus was dominated by Proctoeces maculatus. Prodistomum polonii, was found for the first time in D. annularis in Tunisian waters. Most of the trematode species show a broad flexibility in spatial occurrence and can colonize different parts of the digestive tract. The exceptions are A. microcirrus, P. polonii and Z. rubellus, which are limited to the stomach, the posterior intestine and the rectum, respectively.
