Abstract
Sessile organisms have been thought as related on material deterioration of port and harbour structures. Thus, prevention of sessile organisms is one of main objectives for research and development in this area. Success of macro algae transplantation on mild slope sea wall surrounding Kansai International Airport changed the situation drastically. “Sea Blue Project” and “Eco-Port Policy” followed by “Ecosystem Restoration Work” promotes implementation of symbiosis with ecosystem in port and harbour environment. Multi objective restoration of macro algae habitats, break water design for coral habitat recruitment, and environment assessment using sessile organisms as a indicator are now a new R/D target.
