(see Assessment details)
Assessment rationale/justification
This inshore, pelagic species occurs throughout UAE waters. Fishing activity is not expected to be causing population declines approaching a Near Threatened or threatened level at this time. There are no known major threats; therefore, it is listed as Least Concern in the UAE.

Habitat details as listed in assessment
This semi-pelagic, demersal species schools in nearshore waters from 20-250 m depth, but mostly shallower than 100 m (Mehanna et al. 2013). It reportedly does not occur in water temperatures below 20'°C or with oxygen saturation lower than 30% (Smith-Vaniz 1984). The maximum total length is 38.6 cm (Mehanna et al. 2013). Sexual maturity is attained during the first year at approximately 11 cm total length (Smith-Vaniz 1984). In Omani waters, total length at sexual maturity was about 16.3 cm for males and 17.4 cm for females (Mehanna et al. 2013). This species spawns in the Sea of Oman from August to November, with a peak in September and October (Thangaraja and Al-Aisry 2011, Mehanna et al. 2013). Longevity is at least seven years and natural mortality is estimated as 0.37 (Sabrah 2015). Its estimated generation length is 3.5 years.
