About thirty species of non native marine fi sh appeared in Italian waters during the last fi fty years, a consistent fraction of the total number recorded in the same period in the whole Mediterranean by the CIESM Atlas of Exotic Fish (Golani et al., 2002; 2004; 2007 plus online updating 2005, 2008). Th is number represents an approximation because abundant material is still waiting to be studied. In the present notes I take into account a sample (Table 1) hopefully suffi cient to characterize diff erent groups, in order to separate casual events from those which have ecological signifi cance.

Abstract
About thirty species of non native marine fi sh appeared in Italian waters during the last fi fty years, a consistent fraction of the total number recorded in the same period in the whole Mediterranean by the CIESM Atlas of Exotic Fish (Golani et al., 2002; 2004; 2007 plus online updating 2005, 2008). Th is number represents an approximation because abundant material is still waiting to be studied. In the present notes I take into account a sample (Table 1) hopefully suffi cient to characterize diff erent groups, in order to separate casual events from those which have ecological signifi cance.
