The trout farming, which represents the most important fish production in Italy, can produce negative impacts on river ecosystems, as poured water discharge contains added nutrients and chemotherapic drugs. For the evaluation of trout farming on river ecosystems effects, the seasonal variations of chemical-physical, chemical, microbiological and macrobenthonic indicators were analyzed upstream 100 m and 500 m downstream of 10 industrial trout farms in the centre of Italy. Moreover, for isolated strains of E. coli, the spread of the phenomenon of resistance to antibiotics was evaluated (three antibiotics allowed by current law, and one banned). The results of the comparative analysis of environmental indicators observed upstream and downstream of the trout farms indicate, as a general rule, a modest variation of the chemical, chemical-physical and biological indicators. These results showed a possible illegal use of the Chloramphenicol, currently prohibited in aquaculture. This study contributes to enhance knowledge on aquaculture and its impact on environment and on river ecosystems in particular in the area of Italian Central Apennines.
