Two species of the Teleostean Diplodus Rafinesque, 1810 Sparidae fish, Diplodus sargus (Linnaeus,
1758) (n = 134) and D. annularis (Linnaeus, 1758) (n = 60), from the Algerian west
coast were examined with regards to Digenea parasites occurrence between March 2013 and
December 2014. This investigation led to inventory 12 species of Digenea (Lepidauchen
stenostoma, Arnola microcirrus, Magnibursatus bartolii, Proctoeces maculatus, Holorchis
pycnoporus, Lepocreadium album, Wardula sarguicola, Monorchis sp., Macvicaria crassigula,
Pseudopycnadena fischtali, Diphterostomum brusinae and Zoogonus rubellus). These species
are reported in the selected locality situated in Oran bay for the first time. Furthermore, Lepidauchen
stenostoma in D. annularis is reported for the first time in the western Mediterranean.
The majority of the recorded digeneans colonize one or two parts of the host digestive
tract, the intestine being the most parasitized site. The calculation of epidemiologic indices
provides information on the occurrence of digeneans identified in these two hosts. The diversity
of Digenea is compared with that of the Gulf of Tunis, the Bizerte lagoon and another locality
in the western Mediterranean. The Algerian west coast shows the highest value in the species
richness of digeneans as compared to that of all the Mediterranean coasts.
