   In his presentation, Prof. Emili Garcia-Berthou explained the challenges and opportunities that the ecology of invasive fishes might face with vivid images and languages. With instances of mosquitofish and european sheatfish, he analyzed the features of invasive species, genetic features and adaptability of invasive species, effects of invasive species on native species, etc. 

   Associate Prof. Stefan Schmutz fully explained the lake risk assessment, the effects of hydropower construction on physical and chemical environment of water and aquatic organisms and restoration and conservation of lake ecosystem.
