Habitat

Habitat details as listed in assessment

This is a pelagic migratory fish inhabiting coastal waters to 200 m depth. It sometimes enters turbid estuarine waters, and is usually found in small schools. It feeds mainly on small schooling fishes (especially sardines and anchovies), squids and crustaceans. Adults can reach a maximum fork length of 76 cm. Maturity occurs at around 48-52 cm total length or 1-2 years in southern India, and about 40 cm in Thailand (Krishnarnoorthy 1958). This species may live to 16 years of age (Devaraj 1977). When applying an age at first reproduction of 2 years and longevity of 16 years, its estimated generation length is 9 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction - age at first reproduction)/2.

Assessment rationale/justification

This pelagic, coastal species occurs throughout UAE waters. It is taken in the highly-valued fishery that targets Scomberomorus commerson throughout the Arabian Gulf and Sea of Oman. It is easily confused with S. commerson, and as a result, species-specific data are not available. The population of S. commerson has declined by 50-70% over the past 30 years, and remains overexploited. In addition, fishing effort is increasing. Considering the uncertainty on its population status, and potential major threat from overfishing, it is listed as Data Deficient in the UAE. It is recommended to improve fisheries data collection for this species.
