Digenean species diversity in teleost fish from a nature reserve off Corsica, France (Western Mediterranean), and a comparison with other Mediterranean regions

Data on the digenean parasites of 2238 teleosts from the Scandola Nature Reserve off Corsica are presented. These represent the largest general survey of digenean parasites attempted in the Mediterranean region and is the result of major collections and systematic reports published over the past 20 years. The number of different digenean species recorded from 63 fish species was 102. Full parasite-host and host-parasite lists are presented, with information on the geographical distribution of the parasites, their site within the host and the prevalence, adundance and intensity of the infections. The digenean fauna of teleosts off Corsica is compared with that in other regions of the Mediterranean and the Black Sea. A more detailed analysis of the diversity of these parasites in sparid fishes indicates that the digenean diversity off Corsica is far greater than that in other parts of the Mediterranean.
