Invasive Alien Species have been pointed out as the second cause of species extinction at the world level after habitat loss.
The 12000 alien species known in Europe represent a large threat to the continent's biodiversity.
Among these, aquatic invasive species, both plant and animal pose a serious problem to the biological diversity of freshwaters.
There are 67 inventoried invasive alien species in aquatic ecosystems in Romania, of which 40% fresh water species.
