Distribution of Pseudodactylogyrus anguillae (Monogenea) on the gills of European glass-eels (Anguilla anguilla, L.) in closed-circuit, intensive breeding farms

This study analyses the distribution of a monogenean parasite, the Pseudoda ctylogyrus anguillae, in the gills of European glass eels (Anguilla anguill a). The distribution of the parasite is not casual; both in the postlarval and adult stages, the parasite appears to have a predilection for certain s ites. In the case of infestation by P, anguillae on its own, the parasite h as shown to also occupy those sites which are preferred by the P, bini in c ongeneric infestation.
