Comparative population biology of fish digenes : The case of 3 Helicometra (Trematoda, Opecoelidae) mesoparasites of marine teleosts in a mediterranean lagoon

International audience In the Etang de Thau (Herault, France), three species of Helicometra parasitize in their adult stage the digestive tract of the black goby Gobius niger, the grass goby Zosterisessor ophiocephalus, the grey wrasse Symphodus cinereus, and the common eel Anguilla anguilla (Teleos...
