They ask the Regional Council to "authorize containment measures and selective collection to deal with the excessive presence of cormorants in the Trasimeno lake, in the water basins and along the Umbrian waterways "the regional councilors of the Lega Manuela Puletti and Valerio Mancini, announcing the presentation of a question with which they urge the Executive to “consider the possibility of starting the procedure for this authorization". “In Umbria - explain Puletti and Mancini in a note - the excessive proliferation of cormorants is causing an increasingly significant loss of fish available to lake fish companies and fishermen.
Furthermore, the manure of this species contains a parasite which, settling on the bottom of Lake Trasimeno, enters the life cycle of fish and significantly alters their health and behavior. Lately the number of cormorants in Umbria has increased considerably and currently there are six thousand specimens, which have now become a sedentary species that annually nests on the shores of Lake Trasimeno. But they are also present in other lakes, such as the Faldo in Montone, and the Gatti in Narni, so much so that the problem has taken on a regional nature. Community legislation on the conservation of wild birds allows for exemptions to prevent severe damage to crops, livestock, woods, fishing and waters.
National and regional regulations provide that the Regions can activate species control actions, even in areas where hunting is prohibited, in order to protect their zoo-agro forestry and fish productions. So much so that some Italian regions, such as Lombardy, Veneto, Emilia Romagna and Liguria, experiencing the same problem, have activated the authorization procedures for the selective control of the cormorant. Therefore - conclude the councilors of the League - it is necessary and no longer postponable even in Umbria the implementation of containment and selective removal measures, to limit the damage that the cormorants are causing to the local economy and to the balance of the ecosystem in which they have settled ”.
