    The influence of oxygenation on the immune response of sea bass (Dicentrarchus labrax) to the branchial parasite Diplectanum aequans was studied in the ‘Il Padule’ fish-farm in Castiglione della Pescaia (Grosseto, Italy). The protein fractions of the parasite responsible for the immune response in the fish host were detected, and the sea bass stalled in hyperoxygenation conditions demonstrated a greater antigenic activity and fewer parasites than those reared in normal aeration did

    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 Pseudodactylogyrus anguillae, in the gills of European glass eels (Anguilla anguilla). The distribution of the parasite is not casual; both in the postlarval and adult stages, the parasite appears to have a predilection for certain sites. In the case of infestation by P. anguillae on its own, the parasite has shown to also occupy those sites which are preferred by the P. bini in congeneric infestation
