Assessment rationale/justification
This demersal species inhabits nearshore habitats from estuaries (juveniles) to coral reefs (adults) throughout UAE waters. It is heavily targeted by grouper fisheries throughout the Arabian Gulf and off Oman. It is considered overexploited in the UAE, Oman and the Gulf. In addition, degradation of coral reefs and estuaries is pervasive throughout the Gulf, and is also impacting this species. According to fish market observations, catch data and biomass estimates from scientific surveys, this species has undergone an inferred decline of at least 20-45% and possibly more, since about 1998, or over the past two generation lengths. Conservation measures, including protected areas and fishing regulations (minimum catch length and some fishing license control in Abu Dhabi), have prevented the rate of decline from exceeding 50% at this time; however, fishing effort exceeds sustainability, causing overexploitation to continue. Fishing effort is expected to remain the same or increase in the future time period over the next generation length. Population(s) in areas neighboring the UAE are also in serious decline and it is unlikely that fishing effort is decreasing at a significant level elsewhere. Therefore, this species is listed as Vulnerable A2bcd+4bcd.

Threats listed in assessment
Overfishing is a major threat to this species in the Arabian Gulf (Grandcourt et al. 2005). Degradation of estuaries (juvenile habitat) due to coastal development and pollution may also impact this species. The effects of reduced discharge of the Shatt Al-Arab River caused by damming of the Tigris and Euphrates Rivers has greatly impacted the estuarine habitats in the northern Gulf (Al-Husaini et al. 2015), and caused reduced recruitment in this species (Ben-Hasan et al. 2018). Chlorinated-hydrocarbons (sourced from pollution) have been detected in this species in sampling conducted in the UAE, and this is considered to be an additional stressor to the health of adults of this species (De Mora 2005). 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).
