Effects of 254 nm UV irradiation on the mobility and survival of larvae of the invasive fouling mussel Limnoperna fortunei
In order to investigate the feasibility of using ultraviolet (UV) irradiation to prevent the invasive Asian mussel, Limnoperna fortunei, from colonizing components of the cooling systems of industrial and power plants, the mobility and mortality of its larvae were assessed after exposure to differen...
