Agricultural Environmental Information Engineering Lab
Machine-translated · View original
A lab that studies water movement and water quality in aquaculture ponds and lakes through observation and image analysis.
AboutAbout the lab
Making water environments visible through the movement of water
The lab studies enclosed water bodies such as lakes, reservoirs, and aquaculture ponds, working to clarify how fluid phenomena within these waters relate to water quality changes, heavy metal contamination, and diseases in aquatic systems.
In recent years, the lab has also used ICT equipment for image monitoring and image analysis of aquatic environments to detect environmental changes and visualize signs of anomalies.
The lab conducts on-site observation and sampling of changes in water environments in Thailand, Vietnam, and Bangladesh.
Associate Professor Akinori Ozaki belongs to the International Development Division of the Tropical Agriculture Research Center, and his specialty is environmental hydraulics and water quality science.
Key terms
- Enclosed water body
- A body of water with little inflow and outflow, such as a lake, reservoir, or aquaculture pond
- Cyanobacterial bloom (aoko)
- A phenomenon in which cyanobacteria grow abnormally and spread across the water surface
- Eutrophication
- An excessive increase of nutrients in water

ResearchResearch themes
The lab studies enclosed water bodies such as lakes, reservoirs, and aquaculture ponds in tropical and subtropical regions, working to clarify how fluid phenomena within these waters relate to water quality changes, diseases of aquaculture species, and water pollution.
Abnormal Water Temperatures in Tropical Saltwater Aquaculture Ponds
This research clarifies the processes and mechanisms of heat storage in the water body that occurs in tropical saltwater aquaculture ponds, and determines the actual state of the resulting water quality anomalies and aquaculture diseases.
Heavy Metal Contamination of Surface Water
The lab works to understand the actual state of heavy metal contamination in surface water in Southeast and South Asia and its effects. In Bangladesh and Vietnam, marked heavy metal contamination of groundwater has been confirmed since around the 1990s.
Visualizing and Quantifying Cyanobacterial Blooms
This research uses image analysis to visualize and quantify cyanobacterial blooms (aoko), which occur when cyanobacteria grow abnormally as enclosed water bodies become eutrophic.
Visualizing the Bottom Environment of Aquaculture Ponds
This research uses monitoring of the pond bottom by autonomous boats together with machine learning to visualize the bottom environment of aquaculture ponds, with the aim of supporting production.
