We argue that a multidisciplinary approach is essential to identify deoxygenation impacts on marine ecosystems and fisheries, bridging across the traditionally separate fields of oceanography and economics. Oceanography reveals physical and chemical drivers of deoxygenation, and assesses potential biological impacts based on the physiological and ecological characteristics of organisms and communities. Economics identifies the consequences of human activities associated with the utilization of the changing ocean, particularly in relation to deoxygenation. Economic data, models and analysis can contribute to determining the future directions toward achieving a healthy ocean in the context of deoxygenation. However, differing perspectives on the value of the ocean may lead to conflicts between short-term economic gains and long-term sustainability. Uncertainties in fish populations and deoxygenation modeling add complexity. Despite the difficulties involved, the interdisciplinary view of economics and oceanography offers a more comprehensive understanding of the complexities of ocean deoxygenation and its impacts on both the ocean and people. In order to address the challenges posed by deoxygenation and its impacts, and to develop mitigation and adaptation strategies, it is essential to establish a strong collaboration between experts of oceanography and fisheries economics.
