Development of Navigation, Mooring, and Feeding Modules for Autonomous Robotic Fishing Vessels
Reducing labor associated with feeding operations in marine fish aquaculture is an urgent challenge. There is strong demand for the practical deployment of robotic fishing vessels capable of automated feeding. Key functions of such vessels include automatic berthing and mooring at fish cages. In SBIR Phase 3, we will develop a robotic vessel module that […]
Creation of the World’s Only Aquaculture Fish “Kaiji” through Advanced Germline Stem Cell Manipulation Technologies
Using Tokyo University of Marine Science and Technology’s proprietary “surrogate broodstock technology,” we aim to achieve the social implementation of “Kaiji,” a hybrid fish whose parents are both highly palatable and rare species. In this phase, we will advance the development of commercial-scale aquaculture technologies and conduct comprehensive evaluations of aquaculture suitability. Through social implementation […]
Development of a Low-Cost, High-Performance γ‑Oryzanol Nanoparticle–Enriched Feed to Improve Production Efficiency through Gut Microbiota Modulation in Farmed Fish and Achieve Disease-Free Aquaculture
Although γ‑oryzanol has an established track record as a functional additive in aquaculture feeds for its antioxidant and immune-enhancing effects, its widespread use has been limited by cost constraints. Using our proprietary technology, we nano-formulate γ‑oryzanol, dramatically enhancing its bioavailability. This enables a substantial reduction in inclusion levels, resulting in significant cost reduction. Furthermore, γ‑oryzanol […]
Development of a Wire-Type Sensor for Monitoring Seafood Freshness and Maturation Using Molecularly Imprinted Polymer–Modified Electrodes
In seafood markets, there is a strong demand for objective methods to evaluate seafood freshness. In this project, we are developing a sensor in which molecularly imprinted, immobilized graphite particles are integrated onto a flexible electrode surface and inserted into the bleeding incision of fish. This sensor enables sequential detection of compounds that serve as […]
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 […]
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 […]
