ABSTRACT: For the first time, Emetha audouini (Milne Edwards, 1840), a cymothoid isopod, is reported parasitising cage cultured sea bass Dicentrarchus labrax L., 1758 in Greece. The specimens observed are larvae (Pulli II).
They were found in great numbers in the buccal and branchial cavity of young (3.5 mo old) sea bass, in an intensive cage farm facility. This parasite is certainly transferred to sea bass from wild populations of Sparidae or Centracanthidae. Serious
lesions were visible and typical of a crustacean infection, with extensive and deep skin damage in the head area. The cumulative mortality, over a 2 wk period, was 10.75%. The parasitic problem was successfully dealt with by optimization of management
practices rather than use of costly and dangerous chemotherapeutants.
