In Farm 1 (eastern Greece), ectoparasite prevalence in sea bream and sea bass was 61.5\% and 76.9\% for Monogenea, none for Isopoda, and 0 and 23\% for Copepoda. In Farm 2 the prevalence was 13.3\% and 26.3\% for Monogenea, 13.7\% and 20\% for Isopocla, and 0 and 13.6\% for Copepoda. In the lagoon, the prevalence of ectoparasites was 100\% and 21.9\% for Monogenea and Copepoda, respectively. The lagoon had the highest prevalence of parasites among the studied ecosystems, however, the variety did not significantly affect the health of the infected fish. In Sparidae, gill lesions were due to monogeneans while skin and eye lesions were due to larvae of the isopod Ceratothoa oestroides that caused severe pathology. Furnestinia echeneis and Diplectanum aequans were host specific to sea bream and sea bass, respectively, and persisted in all aquaculture systems. Lemanthropus kroyeri was host specific and detected only in sea bass from the cage farms.}, keywords = {1990 myxosporea, alvarez-pellitero, Copepoda, Crustacea, Dicentrarchus labrax, dicentrarchus-labrax l, ectoparasites, fish, infections, Isopoda, linnaeus, mediterranean fish, parasite, Platyhelminthes, population-dynamics, sea bass, sea bream, Sparus aurata, sparus-aurata, testicularis sitja-bobadilla}, author = {Vagianou, S. and Athanassopoulou, F. and Ragias, V. and Di Cave, D. and Leontides, L. and Golomazou, E.} } @article {10758, title = {Incidence of an intense Caligus minimus Otto 1821, C. pageti Russel, 1925, C. mugilis Brian, 1935 and C. apodus Brian, 1924 infection in lagoon cultured sea bass (Dicentrarchus labrax L.) in Greece}, journal = {AquacultureAquaculture}, volume = {242}, number = {1-4}, year = {2004}, note = {TY - JOURExport Date: 5 September 2006Source: ScopusReferences: Athanassopoulou, F., Bouboulis, D., Martinsen, B., In vitro treatments of deltamethrin against the isopod Ceratothoea oestroides, a pathogen of seabass D. labrax L.

Our data indicate that both eastern (Greece and Egypt) and northwestern (French coast) populations of D. labrax were genetically differentiated from the Tyrrhenian ones, which were nearly indistinguishable from each other at the cyt b level. The D. labrax population from the Atlantic coast (Portugal) was genetically quite distinct from all the Mediterranean ones. These results strongly confirm the conclusions from previous studies where the same populations were screened for allozymes, random amplified polymorphic DNA (RAPD) and mitochondrial DNA (mtDNA) D-loop variation. Seven other species of Perciformes belonging to five different families (Sparidae, Serranidae, Carangidae, Pomatomidae, Sciaenidae) were sequenced to explore the usefulness of the cyt b gene for inferring evolutionary relationships at different hierarchical levels. The data were analysed together with other published cyt b sequences from Perciformes fishes. Our data suggest that the superfamily Percoidea is not monophyletic. At the family level, the Sparidae and Moronidae seem to be monophyletic. The evolutionary relationships among families were not resolved.
