Presenza e distribuzione di fauna ittica alloctona nel reticolo idrografico delle province di Treviso e Belluno.

The study of presence and distribution of alien fauna fish in the provincial territory of Treviso, was based on the updating of the new Fish Paper 2008-2010. In the provincial territory of Belluno we have considered data derived from investigations used for the updating 2010-2014 of the provincial Fish Paper. Moreover we have considered two important artificial basins, Corlo lake and Cadore lake, that were studied during 2009 and 2010. Our investigations consider the great part of water bodies of Belluno and Treviso hydrographic network. In the Treviso province we considered 95 stations on wich there were found 12 alien species in 37 total fish species. In the Belluno province we considered 103 stations and lakes and we individualized 2 alien species in 17 total fish species. In lakes we found 2 alien species.
