The Omani shelf warning from the deep
Oxygen minimum zones (hypoxic zones), reported for over 400 geographical regions, is a key stressor of coastal ecosystems worldwide. Not surprisingly, hypoxia has become a serious environmental challenge to fishery management.
As one of the most prominent oxygen depletions of the ocean, the Arabian Sea oxygen minimum zone extends from the central part of the basin to the coasts of Oman, Iran, Pakistan and India and makes fisheries vulnerable to the shelf hypoxia. Shelf oxygen depletion causes numerous fish kill incidents along the Omani coast. Nevertheless, temporal variability of the shelf hypoxia and its impact on fish catches are still poorly investigated.
