Assessment rationale/justification
The Sandbar Shark occurs throughout UAE inshore and offshore waters. It is caught with longlines, hook-and-line, and set bottom nets and the fins are generally considered to be of high value. While there is limited information available on this species in the region, its large size, valuable fins and intensive fisheries mean that, like many other large carcharhinids in the region, it has declined significantly. In addition, this is one of the least biologically productive sharks, with high intrinsic vulnerability, and information from other parts of its global range have demonstrated that it is quickly overfished even with moderate levels of fishing. Little specific data are available for this species in the UAE. It is especially susceptible to exploitation (target and bycatch) in many largely unregulated gill net, longline and trawl fisheries that operate within its range outside and surrounding UAE waters. Some management measures are now in place in the Arabian Sea region, although domestic fisheries are likely to continue. Though data specifically from the UAE are not available, individuals in the UAE are a component of a larger, interconnected and migratory population that occurs broadly in the north-western Indian Ocean. It is inferred that declines reported in the Arabian Sea region are representative of its status in the UAE. Based on recorded levels of exploitation and decline in habitat quality, it is suspected to have declined by at least 50% over the past three generation lengths, or about 86 years. It is listed as Endangered A2cd.

Threats listed in assessment
In the UAE, sharks have been impacted by targeted commercial fisheries until 2014 when a ban on export of sharks was imposed (Ministry of Climate Change and Environment). Sharks continue to be impacted by artisanal and bycatch fisheries (Annual Fisheries Statistical Report for Abu Dhabi Emirate 2001-2018), though catch data are not species-specific. Studies show that sandbar sharks are a long-lived species with low fecundity and are very susceptible to overfishing (Springer 1960, Casey et al. 1985, Sminkey and Musick 1995, 1996; McAuley et al. 2005, 2006). Marine habitats in the region have experienced high levels of disturbance and are quickly deteriorating due to major impacts from development activities (Sheppard et al. 2010). 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).
