     Coral reef ecosystem is one of the most productive and diverse marine ecosystems in the world. In the western Arabian Gulf, it supports more than 50 % of the fishes which are consumed by the fisheries sector and provides an excellent site for marine ecotourism. However, the coral ecosystem in this region is at risk due to a combination of recurring heating events and human activities. In this seminar, discussion will be carried out on the decline of corals in the western Arabian Gulf, its associated impacts and immediate measures which needs to be undertaken. The live coral coverage in the western Arabian Gulf was more than 50 % during the 1980s and early 1990s while it got reduced to less than 10 % for most of the reefs in 2020. The response of fish to this declined coral coverage is a decrease in their abundance, with a lag of mostly 8 years. The lagged response of fish suggests the importance of long-term and continuous monitoring which is required for this crucial ecosystem. Active restoration of the coral ecosystem is needed to compensate its nature of slow growth and fast degradation.
