Participants in 45 Th UJNR Aquaculture Panel Symposium, Held in International Conference Center Hiroshima, Hiroshima, Japan Participants in 45th UJNR Aquaculture Panel Symposium, held in International Conference Center Hiroshima, Hiroshima, Japan, October 16 ‒ 17, 2017 Preface The UJNR (The U.S.-Japan Cooperative Program in Natural Resources) Aquaculture Panel was established in 1968, and the business meeting and symposium have been held every year since 1971. Through the long history of UJNR, Aquaculture Panel has contributed to the development of aquaculture researches of both countries by means of various cooperative activities, such as the exchange of scientists and literatures, and the promotion of joint research projects. The Aquaculture Panel is highly appraised as one of the most active UJNR panels in both countries. The 45th Business Meeting of the UJNR Aquaculture Panel was conducted at Conference Center Hiroshima, Hiroshima Prefecture, Japan on October 16, 2017, and the Scientific Mini-Symposium was held at the same venue from October 17 to 18. The symposium theme was "Potential of aquaculture to mitigate impacts of environmental change", which was under the 10th Three-Year Plan, "Marine Aquaculture in a Changing Environment", commenced in 2017. Fifteen oral presentations were made on topics such as environmental change, environmental remediation, biological response to environmental change and ecosystem approach to aquaculture, and seven poster presentations were also made on broader topics related to aquaculture during the two-day symposium. The proceedings of the 45th UJNR Aquaculture Panel Scientific Mini Symposium "Potential of aquaculture to mitigate impacts of environmental change" is published as the special issue of the Bulletin of Japan Fisheries Research and Education Agency. With great pleasure, this UJNR proceedings containing high quality papers authored by selected American and Japanese aquaculture scientists will hopefully help improve the aquaculture environment programs, which is expected to contribute to the development of the aquaculture industry in both the United States and Japan. Finally, I would like to express my sincere gratitude to the colleagues involved in the UJNR Aquaculture Panel for their efforts in the preparation and organization of the symposium. I would also like to deeply thank the editorial board members for publishing the proceedings.

Nutrient pollution is driving eutrophication and dead zones; ocean acidification is changing water chemistry, and climate change is already influencing our food supply, fresh water availability, weather and way of life. Aquaculture will be impacted by, and can also impact, these environmental changes over various time and spatial scales. Aquaculture of finfish, shellfish and seaweed have different threats, benefits and opportunities related to environmental change. Understanding the global and regional trend of climate change, effects of environmental change on ecosystem and aquaculture, technical improvement of aquaculture, and aquaculture industrial adaptation to climate change are all research priorities of the National Ocean and Atmospheric Administration (NOAA), the United States Department of Agriculture (USDA) and the Japan Fisheries Research and Education Agency (FRA). The primary focus of this symposium will be on the potential of aquaculture to mitigate impacts of environmental change, such as sequestering carbon, bio-extraction of nutrients and CO2, and ocean acidification. We hope to exchange ideas and discussion which will be beneficial in exploring science and technology that will enable aquaculture to sustain in a changing environment and be used to mitigate the anthropogenic impacts on environment. We also hope the exchanged ideas will be developed into our collaborative research efforts to resolve key issues and assist strengthening of aquaculture industry in the United States and Japan.

Moors Copernicus Institute of Sustainable Development [email protected] +31 30 253 7812 Second Reader: Dr. Koen Beumer Summary A sustainability transition in the agri-food regime is urgently required to interrupt the strong reciprocal effect between current food production standards and climate change (Willett et al., 2019). One sustainable innovation in the agri-food sector is aquaponics. Aquaponics is the combination of hydroponics and recirculating aquaculture in one controlled environment (Somerville, Cohen, Pantanella, Stankus & Lovatelli, 2014). At first sight, the water and nutrient-saving character of aquaponics, amongst other features (Somerville et al., 2014), sound promising for a transition towards sustainable agriculture. Therefore, the following research question emerged: How can the emerging aquaponics technology contribute to the sustainability transition in the Dutch agri- food sector based on Dutch aquaponics developments in the period 2008-2018? To answer this overarching research question, three sub-questions were developed. An integrated framework combining the multilevel perspective (MLP) and the technological innovation system (TIS) was used to understand the dynamics between overall structural trends, the current Dutch agri-food sector and the emerging aquaponics innovation. The innovation was also set into a broader European context. The research was of exploratory nature and used a qualitative content analysis to process 23 interviews, scientific articles, practitioner websites, publication, patent and Google Trend statistics, etc.

    7th International Conference on Innovation in Chemical, Agricultural, Biological and Environmental Sciences (ICABES-2017) London (UK) Dec. 4-6, 2017 Thoughts on Algae Cultivation toward an Expansion of Aquaculture to the Scale of Agriculture Amir Neori and Lior Guttman National Center for Mariculture, Eilat, Israel Oceanographic & Limnological Research, Eilat, Israel Abstract: Today’s fish - dominated seafood consumption pattern cannot be sustained, since supply has shifted from capture to culture (each currently at around 100 million tons/y). Already today, seaweeds (macroalgae) and shellfish dominate mariculture. To prevent crises, wise policies could anticipate this inevitable shift, by promoting seaweed and shellfish production and consumption. The current rate of expansion in mariculture production will inevitably rise in the long run. Eventually, the seafood share in global food supplies, primarily in 3rd world countries, will rise, with the emerging global exhaustion of arable land and freshwater reserves. The sea remains the world’s last food frontier – the only environment that is still available for expansion of food production. A sustainable expansion of seafood culture by orders of magnitude necessitates a balance, as in agriculture, between fed aquatic animals (fish, shrimp…) and extractive plants and animals (bivalves, detritivores). Extractive organisms ameliorate the environmental impacts of the fed animals’ farming, while bringing more income and jobs. Cultured seaweeds, with their biochemical composition and high protein content, can also replace much of the fishmeal in aquaculture diets and provide humanity with nutritious protein.

Cork, Ireland; [email protected] * Correspondence: [email protected], Tel.: +353-(0)27-62-990 Academic Editor: M. Haïssam Jijakli Received: 16 October 2016; Accepted: 8 December 2016; Published: 16 December 2016 Abstract: The demand for seafood products on the global market is rising, particularly in Asia, as affluence and appreciation of the health benefits of seafood increase. This is coupled with a capture fishery that, at best, is set for stagnation and, at worst, significant collapse. Global aquaculture is the fastest growing sector of the food industry and currently accounts for approximately 45.6% of the world’s fish consumption. However, the rapid development of extensive and semi-extensive systems, particularly intensive marine-fed aquaculture, has resulted in worldwide concern about the potential environmental, economic, and social impacts of such systems. In recent years, there has been a significant amount of research conducted on the development of sustainable saltwater-based food production systems through mechanical (e.g., recirculatory aquaculture (RAS) systems) methods and ecosystem-based approaches (e.g., integrated multi-trophic aquaculture (IMTA)). This review article will examine the potential negative impacts of monocultural saltwater aquaculture operations and review established (RAS) and novel (IMTA; constructed wetlands; saltwater aquaponics) saltwater-based food production systems and discuss their (potential) contribution to the development of sustainable and environmentally-friendly systems.

Received: 23 December 2013; in revised form: 24 January 2014 / Accepted: 8 February 2014 / Published: 20 February 2014 Abstract: Many aquaculture systems generate high amounts of wastewater containing compounds such as suspended solids, total nitrogen and total phosphorus. Today, aquaculture is imperative because fish demand is increasing. However, the load of waste is directly proportional to the fish production. Therefore, it is necessary to develop more intensive fish culture with efficient systems for wastewater treatment. A number of physical, chemical and biological methods used in conventional wastewater treatment have been applied in aquaculture systems. Constructed wetlands technology is becoming more and more important in recirculating aquaculture systems (RAS) because wetlands have proven to be well-established and a cost-effective method for treating wastewater. This review gives an overview about possibilities to avoid the pollution of water resources; it focuses initially on the use of systems combining aquaculture and plants with a historical review of aquaculture and the treatment of its effluents.

  • Challenges and Opportunities of IMTA in Hawaii and Beyond
    水 研 機 構 研 報， 第 49 号，129 － 134， 平 成 31 年 Bull. Jap. Fish. Res. Edu. Agen. No. 49，129－134，2019 129 Challenges and opportunities of IMTA in Hawaii and beyond Cheng Sheng Lee＊ Abstract: Available consumable seafood for 7.3 billion population in 2014 was 20 kg per capita (FAO, 2016). To maintain this level of seafood supply for expected 9.7 billion population in 2050, the total world seafood supply requires additional 48 million metric tonnes. With the stagnant yield from capture fisheries, the increase has to come from aquaculture. Although the annual growth of aquaculture production has slowed down, theoretically aquaculture production will reach the targeted production level. However, current intensive mono-aquaculture practices have faced the challenges of sustainability and must change its operation to meet the criteria of sustainable development defined and adopted by UN’s 193 Member in 2015. UN members adopted the 2030 Agenda for Sustainable Development and call for an integrated approach that addresses all three dimensions of sustainable development (economic, social and environmental). Current aquaculture practices consume nature resources and compete with each other. Ecosystem based aquaculture management is essential to co-exist with other social activities and to efficiently utilize natural resources for food production and conservation of nature stocks. Integrated multi- trophic aquaculture (IMTA), an old concept with new knowledge, appears to be the answer to sustainable development in aquaculture. IMTA practice combines the cultivation of fed aquaculture species, and extractive aquaculture species (both organic and inorganic ones) to reduce wastes and to create balanced eco-systems.
