Trout is one of the oldest products offered by European aquaculture, being traditionally produced by small local farms that are firmly rooted in their home territory. Italy is one of the main producer, with an important internal market and exports to Germany and Switzerland. Trentino, in the North East of Italy, with plenty of pristine waters from the world famous Dolomites mountains – candidate as Unesco World Natural Heritage site -, is the main production area in Italy, with a tradition of trout farming dating back to 1879. Trentino’s trout was highly appreciated as delicacy also by the Court in Wien for their Royal banquets. The longstanding aquaculture tradition in Trentino could represent enough evidence of sustainability of production.
