This paper explains how the new technologies of artificial intelligence, bio-expert-systems, mechatronic environmental-control, virtual reality technology, GIS (Geographical Information System), can be appreciated to build up the innovative fishway system. The basic theories of this system are cybernetics and imprinting. We can use the smart sensors, for example, ultrasonic sensors, underwater cameras, those of which look forward to fish position in the river, and we can understand the behavior of fishes. The artificial intelligence of this system shall choose the most suitable environment from which the knowledge bases, such as the physiology of fish knowledge base, furnish the various environmental menus, and then control the river environment by the mechatronic pumping systems from the sea water and bio-reactor tank. These processes should be carried out automatically by computer. This system is most effective especially in the brackish water zone, in which the sea water and the upstream fresh water meet.
