(see Assessment details)

Assessment rationale/justification

This pelagic speciesoccurs in UAE waters only in the Sea of Oman. Fishing activity is not expected to be causing population declines at this time. There are no known major threats; therefore, it is listed as Least Concern in the UAE.

Taxon distribution as listed in assessment

In the UAE, this species occurs only in the Sea of Oman. It is excluded from the Arabian Gulf. Elsewhere, it is circumglobally distributed in tropical waters (Smith-Vaniz 1986, Smith-Vaniz 2002, Simon et al. 2013). The depth range is 1-400 m, but is more common from 0-200 m (Smith-Vaniz 1986, Mundy 2005).

Habitat

Habitat details as listed in assessment

This species schools in open water, occasionally over outer reefs and frequently around islands. It feeds primarily on zooplankton (Cervigón et al. 1992, Smith-Vaniz 1995). The maximum size is 46 cm total length, and is common to about 25 cm fork length (Smith-Vaniz 2002, Jiménez and Béarez 2004). In Japan, the length at 50% maturity of females was estimated at 25.8 cm and age at maturity at two years old (Shiraishi et al. 2010). In Cape Verde, length at first maturity is 22 cm (Monteiro pers. comm. 2012).

Threats and conservation measures listed

Threats listed in assessment

Fishing activity is not known to be driving declines in the UAE at this time. 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).
