Development of a Digital System to Streamline Seafood Trading Operations at Local Fish Markets
Many production-area fish markets, which play a vital role in supplying domestic seafood, are located in regions facing severe depopulation and population aging, making labor shortages an extremely serious challenge. To address this issue, we are developing a digital seafood trading system that enables labor-saving operations by collecting landing information as digital data, conducting electronic […]
Labor-Saving Monitoring of Fisheries Resources and Aquatic Environments Using Fully Automated Systems Based on Environmental DNA (eDNA) Technology
To dramatically reduce labor requirements and enhance the sophistication of continuous monitoring of fisheries resources, including fish, using environmental DNA (eDNA) technology, we aim to commercialize a compact, low-cost, and practical device called the “eDNA Sampler.” Centered on the manufacturing and sale of the eDNA Sampler, we plan to establish a startup company that also […]
Development of Biomass-Based Feed for Rearing Cold-Water High-Value Fish and Shellfish Using Underutilized Local Resources
With the aim of strengthening the production capacity of high-growth, high-quality cold-water premium fish and shellfish, we will develop collection and primary processing technologies to enable the mass utilization of food processing by-products, primarily generated in the Tohoku region, as feed ingredients. Using these technologies, we will manufacture nutrient-rich, highly functional biomass feed and supply […]
Improvement of SPALOW (Solar-Powered AirLift for Ocean Water), a Self-Sustaining Seabed Water-Lifting System, for the Practical Deployment and Widespread Adoption of Oyster Aquaculture
Through prior research and development, we have prototyped a self-sustaining seabed water-lifting system that enables increased production of cultured oysters. The system lifts 10 tons of nutrient-rich bottom seawater per hour, together with seabed sediments containing high-quality plankton, which serve as food for oysters. As a result, we achieved a 48% increase in shucked meat […]
Development of an Integrated Coastal Monitoring System for Sustainable Fisheries
To realize sustainable fisheries, we are developing an integrated coastal monitoring and data analytics system that covers both terrestrial and marine domains. Through this research, we aim to elucidate how terrestrial economic activities—including agriculture and industry—as well as meteorological conditions, interact with and influence marine fisheries. By clarifying these land–sea interactions, the project seeks to […]
Development of a Fleet Network System Using VDES
In fisheries that operate in vessel fleets, effective information sharing significantly improves operational efficiency. In offshore areas where internet connectivity is unavailable, communication still relies primarily on voice radio, highlighting the need for a more efficient alternative. In this project, we are developing a fleet networking technology based on VDES, a next‑generation maritime digital communication […]
Development of a Closed-Loop Land-Based Aquaculture System and Feed to Promote the Utilization of Urchins from Barren Coastal Areas
Closed‑recirculating land‑based aquaculture systems equipped with ozone‑based water purification can process multiple purification steps in an integrated manner. However, when rearing water becomes heavily contaminated, denitrification of harmful ammonia can be inhibited, posing a critical operational challenge. In this study, we utilize sea urchins removed as part of barren‑ground (isoyake) mitigation efforts and pursue two […]
Advancement of Cell Culture Technologies Toward the Realization of Cultured Eel Meat
In this study, we aim to establish large‑scale culture technologies for Japanese eel (Anguilla japonica) myoblasts and adipocytes, and to develop foundational technologies for the commercialization of cultured eel meat. By combining stirred‑tank bioreactors with immobilized cell culture bioreactors, we will optimize cell proliferation and differentiation to achieve high‑density, large‑scale cell production. In addition, to […]
AQSim, an aquaculture support software that predicts both profitability and CO₂ emissions of land-based aquaculture systems
In recent years, land-based aquaculture has attracted growing attention; however, it faces challenges including higher operating costs and greater CO₂ emissions compared to sea-based aquaculture. In this study, we will develop “AQSim,” an aquaculture support software that predicts both profitability and CO₂ emissions of land-based aquaculture systems. AQSim will be validated through demonstration trials using […]
