Abstract

Ocean deoxygenation, a consequence of climate change and nutrient pollution, significantly impacts marine food webs and ecosystems. This article investigates the effects of reduced oxygen levels on marine food webs, focusing on species distribution, trophic interactions, and ecosystem functioning. By analyzing recent studies and case examples,we explore the mechanisms through which deoxygenation disrupts marine organisms and its implications for fisheries management. The findings highlight the challenges of adapting management strategies to address these changes and offer recommendations for enhancing resilience. Integrating real-time monitoring, adaptive management, and pollution reduction strategies are essential for mitigating the impacts of deoxygenation and ensuring sustainable fisheries.
