BEAM TECHNOLOGIES INC. (Tokyo, Japan; Co-CEOs: Kazuki Iimura and Yuuri Itokazu) is pleased to announce that it has been selected for the open innovation program “TSUBASA2025 (Business Course),” co-hosted by the Japan International Cooperation Agency (JICA) and IDB Lab, the innovation laboratory of the Inter-American Development Bank Group. The selected project involves the digital transformation (DX) of shrimp farming in the Republic of Ecuador through the utilization of Far-UVC and IoT technologies, aimed at addressing SDGs and development challenges in the Latin America and Caribbean region. ○Current Status and Challenges of Shrimp Farming in Ecuador The Latin America and Caribbean region have an economy 1.5 times larger than that of ASEAN (in nominal GDP), and shrimp farming is one of its key industries with significant economic importance. Ecuador has grown into the world’s largest shrimp exporter, and its production volume now serves as a vital pillar of the national economy. However, the aquaculture industry faces issues such as decreased productivity due to disease, environmental burdens, and inefficiencies stemming from traditional farming methods. In shrimp farming, in particular, water quality management and early detection of disease are essential for improving productivity and sustainability. ○Overview of This DX Project This project aims to improve the productivity of shrimp farming, reduce the risk of disease, and reduce the environmental impact of shrimp farming in Ecuador by combining our Far-UVC (deep ultraviolet) technology with IoT technology. Specifically, we will promote the following initiatives. 1. Disease control and water quality control with Far-UVC technology: Far-UVC is an ultraviolet light with a wavelength that is considered safe for humans, but it can efficiently inactivate bacteria and viruses. By installing a Far-UVC system in the fish farm, the risk of disease in shrimp is significantly reduced by reducing the amount of pathogens in the water while reducing the amount of chemicals used. This contributes to reducing the use of antibiotics and maintaining a healthy growth environment. 2. Centralized management and optimization of aquaculture data with IoT technology: Water quality data such as water temperature, oxygen concentration, pH value, shrimp growth, and feeding volume are monitored in real time and aggregated in the cloud through IoT devices. As a result, aquaculture operators will be able to grasp the status of aquaculture ponds at any time from their smartphones and PCs, enabling them to make scientific decisions based on data. 3. Predictive detection and productivity improvement through the use of AI: By using AI to analyze accumulated big data, it is possible to detect signs of disease outbreak and signs of deterioration of water quality at an early stage and take appropriate measures. This minimizes accidental damage and contributes to improved yields and increased productivity. ○Significance of the adoption of the "TSUBASA2025"The TSUBASA project is an epoch-making program that aims to solve development issues in Latin America and the Caribbean through co-creation between Japan start-ups and JICA and IDB Lab. This selection recognizes the potential of our Far-UVC and IoT technologies to contribute to solving urgent issues in the shrimp farming industry in Ecuador and promote sustainable economic and social development. With the strong support of JICA and IDB Lab, as well as the utilization of our local network, we aim to accelerate the DX of the shrimp farming industry in Latin America and the Caribbean, starting with Ecuador. In addition, in anticipation of the full-scale development of this project, we are moving forward with a plan to establish a local joint venture in Ecuador in 2026, aiming for sustainable business growth while strengthening cooperation with local communities. Through this project, we will contribute to the economic and social development of the Latin America and the Caribbean region and the reduction of environmental impact, and further enhance our presence in the global market. ○Future Outlook: Realizing the “Aqua Medical Initiative” in Shrimp Farming BEAM TECHNOLOGIES INC. regards this project not merely as an effort to increase productivity but as the first step toward realizing the “Aqua Medical Initiative” for land-based aquaculture centered around shrimp farming. Inspired by human healthcare services, this initiative aims to comprehensively support the health management of shrimp and other species. Specifically, we aim to develop the following services. 1. Advancement of Disease Diagnostics (Consultation & Diagnosis): Combining real-time data from IoT sensors with AI analysis, signs of disease in shrimp can be detected at an early stage, enabling fast and accurate diagnosis. This is equivalent to human health checkups and early disease detection. 2. Environmental improvement (Treatment & Prevention) through Sterilization: Far-UVC technology is used to effectively sterilize and remove pathogens in aquaculture water to maintain a clean environment where shrimp can grow healthy. This is an approach that is equivalent to preventive medicine and infectious disease treatment. 3. Periodic Monitoring Service (Follow-up and Health Management): Continuous data collection and analysis, we constantly "visualize" the health status of shrimp and the aquaculture environment, and build a system that can respond immediately if there is an abnormality. This supports long-term health management, such as regular human checkups and follow-up of chronic diseases. By introducing the concept of “preventive care” into shrimp farming, BEAM Technologies aims to shift from reactive treatment to proactive management, contributing to sustainable and stable shrimp production.
