Macroparasite community of the European eel, Anguilla anguilla, in Mediterranean lagoons with particular focus on invasive species, Anguillicola crassus and Pseudodactylogyrus spp.
International audience European eel parasites, in particular invasive species, are suspected to play a role in the decline in the populations of their host. The aims of this work were to describe the parasitic fauna of eels in French Mediterranean lagoons and to study the epidemiological trends of t...
