Taxon distribution as listed in assessment
This species occurs throughout UAE waters. Globally, it is widespread in the Indo-West Pacific (Smith-Vaniz 1984, Randall et al. 1997, Smith-Vaniz 1999, Leis et al. 2006). The depth range is 10 to 188 m (Mundy 2005).

Habitat details as listed in assessment
This pelagic speciesschools in a variety of habitats, including rocky and coral reefs and inshore sand flats (Lieske and Myers 1994, Wetherbee et al. 2004, Mundy 2005). Adults are solitary or in schools, and juveniles occur in small schools over sandy inshore bottoms and occasionally in turbid estuaries (Blaber and Cyrus1983, Myers 1999). The presence of estuarine habitat is not necessary for this speciesto thrive (Sudekum et al. 1991). Itfeeds during the day, mostly on demersal and pelagic fishes, but also cephalopods and crustaceans (Blaber and Cyprus1983, Sudekum et al. 1991). This species forms spawning aggregations on shallow seaward reefs and offshore banks (Sudekum et al. 1991, de Silva et al. 2014).This speciesis one of the largest of the carangid fishes, measuring up to 170 cm total length (Lieske and Myers 1994). It can live to at least 20 years of age and has been recorded to 30 years of age in captivity (Friedlander and Dalzell 2004). Femalesreach maturity at approximately 60 cm and 3-4 years of age (Sudekum et al. 1991). When applying an age at first reproduction of 4 years and longevity of 20 years, its estimated generation length is 12 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 inshore, pelagic species occurs throughout UAE waters, and is a valued food fish in UAE fisheries. Catch in Abu Dhabi declined by at least 82% between 2009-2018, but the cause of these declines is very poorly understood. No stock assessments have been conducted or are scheduled. The status of population(s) outside the UAE is not well-understood, but the species is also frequently taken in fisheries elsewhere. Based on the uncertainty regarding the population trend of this exploited species, it is listed as Data Deficient in UAE waters until updated data become available. Improvements in fisheries monitoring are needed.

Threats listed in assessment
Overexploitation is a potential major threat to this species in the UAE. Ithas experienced declines in human-populated areas in some parts of its range due to fishing (DeMartini et al. 2002, Meyer et al. 2007). This species is relatively long-lived and has a large maximum body size, which may cause it to have low resiliency to heavy fishing pressure. Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).
