Aquatic food production is currently facing increasing challenges, and its sustainability in the future is in jeopardy. The issues surrounding aquatic food production include the growing pressure for increased production due to global population growth, particularly in developing countries, which will continue until the mid-2080s; population decline and aging in developed countries, leading to a reduced labor force; the evident limitations of biological and non-biological resources in aquatic ecosystems (with current production methods utilizing resources to their maximum limits); and the disruption of marine ecosystems caused by global climate change and ocean warming. To ensure the stable supply of high-quality, safe, and secure seafood in the future, it is essential to enhance production through innovative methods, actively conserve aquatic ecosystems, and develop resource-circulating production systems that reduce food loss, all of which must be realized through collaborative systems across various industrial sectors. Additionally, it is crucial to promote a shift in consumer awareness regarding seafood consumption. This paper discusses these issues and presents examples of practical measures being implemented, such as the technological development of full-cycle aquaculture of Pacific bluefin tuna (Thunnus orientalis) and mottled spinefoot (Siganus fuscescens) in Kindai University, as well as the growing trend of land-based aquaculture worldwide in recent years including completely closed circuit systems.
