Assessment rationale/justification
This species occurs throughout inshore waters of the UAE. It is targeted by commercial fisheries, and is considered overexploited in the UAE. Based on catch data and stock assessments, this species has undergone an inferred decline of at least 50% and possibly more over the past two generation lengths, or 14 years. With recent fisheries management measures implemented in Abu Dhabi, it is difficult to say whether fishing effort will continue to increase or decrease within the near future; however, effort in this fishery in surrounding Emirates where management measures are not stringent may increase or remain the same. Considering that other Emirates and surrounding countries that likely share this stock do not have management measures in place to reduce effort in the gargoor fishery, population declines are expected to continue. In addition, degradation of coastal habitats, especially for coral reefs is ongoing in the UAE and Arabian Gulf region. The population in UAE is inferred to have some level of connectivity with those in surrounding countries, and declines have been documented in Qatar and possibly Iran. It is listed as Endangered A2bcd+A4bcd.

Threats listed in assessment
Overfishing is a major threat to this species in the UAE and off Qatar (Grandcourt et al. 2006). Coastal development in the UAE and Arabian Gulf region, which includes degradation of estuaries, may also impact this species. 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).
