Marine Innovation Technologies for Aquaculture and Underwater Research


Dr Leo Chan,
Associate Director,


At present, Hong Kong and mainland China lag behind in the application of marine innovation technologies in marine environmental research and monitoring. Through the acquisition of proven sensor technologies, marine innovation technology platforms have been established to facilitate in situ ocean exploration and research.

Three major threats to sea-cage mariculture in Hong Kong are disease, harmful algal blooms (commonly called red tides) and pollution. In collaboration with the School of Veterinary Medicine, innovation and ecosystem-based mariculture approaches have been developed and explored to address these challenges.

In the past, diving was overlooked, owing to the cultural misperception that it is merely a recreational tool that adds some value to shallow water sciences. In reality, placing researchers within the underwater environment to be themselves effective tools offers unparalleled abilities - human senses, spatial awareness, cognitive interpretation, and so on. Advanced scientific diving technologies and methods are continuously making new breakthroughs and are making untapped biological, genetic and chemical diversity within human reach. All of this has the potential for new human benefits.
