- Seafood and Aquaculture System
Sustainability has become a global mission. However, it is not easy to reconcile resource and environmental constraints with the economy, and a shift in the social model is needed.
As a solution, the University of the Ryukyus aims to form a circular society model for "Food" and "Energy" based in Okinawa. Its basic approach should not be optimization of individual problems, but rather total optimization, in which multiple problems are interconnected and solved comprehensively.
This project aims to develop technologies for land-based recirculating aquaculture system, efficient operation of electric power, and agricultural production including aquaponics under the three targets of "Food," "Energy," and "Information," and to realize an optimal circular society by linking these technologies with digital technology.
Establishment of infrastructure for efficient "Food" circulation
Development of fundamental technologies for "Energy" circulation
Advanced technology development to enable the effective use of "Information"
We are “Center of Excellence of the Sustainable Integration of Land-based Aquaculture with Agriculture to build the Resource Circular Symbiotic Society”, which was adopted as “The Program on Open Innovation Platform for Industry-academia Co-creation” by Japan Science and Technology Agency (JST).
Future efforts will be to advance new R&D subject derived from the Center's vision and targets, and to upgrade them while adding research functions in line with social trends and information innovation.
We will also hold regular Future Design Workshops in which young people, who will be responsible for the future, will be proactively involved, and we will continue to develop and share the vision and targets of the Center.
Difficulty in food supply
due to population growth
Protein demand may increase 1.5 times by 2040, leading to a "Protein Crisis"
Japan has only 6.9% renewable energy, which makes a large gap from "Zero Emissions".
Adverse effects of food waste are
becoming more serious
About 1.3 billion tons of food, or 1/3 of the world's food production, is thrown away.
Lack of bearers makes
fishery management difficult
The average age of fishermen is 56.9 years old, and the number of fishermen is expected to decrease by 33% over the next 10 years in Japan.
This facility aims to research land-based aquaculture by renewable energy and technical development for the growth promotion of seafood.
This area beside from NAICe is an important base for research on photovoltaics. Researchers are continuously taking data from the integrated system.
Aquaponics is a technique that combines hydroponics and land-based aquaculture, and a container-type aquaponics facility has been established at the University of the Ryukyus in 2023. This facility will be used as a base for conducting research on aquaponics using seawater.
ARK is a small land-based aquaculture facility with a closed circulation system that allows farmed fish to be raised without discharging water. Prior to the completion of the Okinawa model, a demonstration test of the closed-recirculation system using the ARK will be conducted.
