Automatic Water Quality Monitoring Device "Medaka Bioassay"

The medaka fish will continuously monitor for the contamination of toxic substances in river water and groundwater from water supply and food factories 24 hours a day. This contributes to corporate risk management.

The excellence of fish monitoring lies in its ability to respond to unknown toxins and complex toxins. The medaka is a designated test fish by the OECD (Organisation for Economic Co-operation and Development). A bioassay refers to a biological testing method. "Medaka Bioassay" has already been introduced in over 140 units across public water systems, food factories, chemical and machinery factories, from Hokkaido to Okinawa. It is a groundbreaking product that merges fish biology (natural science) with image processing (electronic engineering). Our company’s representative has been a pioneer in linking fundamental research to practical application for about 40 years since his time as a university professor. The extensive experimental data is provided as a "toxin library." 【Features】 ■ Fish respond to 97% of 970 types of acute toxic chemicals affecting humans. ■ Continuous automatic monitoring of water quality for 24 hours. ■ Movement of medaka is analyzed using CCD cameras and image processing technology. ■ Continuous testing can be performed even with highly turbid raw water. ■ It can detect trace amounts of toxins from sources such as groundwater. ■ A system for transmitting data and images to remote locations is possible. ■ Raw water with odors can be detected using an odor sensor. *For more details, please refer to the PDF document or feel free to contact us.
