Assessment rationale/justification
This inshore species occurs throughout UAE waters. It is exploited throughout the UAE, but species-specific catch data are not collected. It comprises a smaller proportion of the mullet catch than Crenimugil seheli, but catch in that fishery declined by about 80% over the past 11 years. Fishing effort trends are not well-understood. It is also exploited in areas neighbouring the UAE. In addition, the difficulty in distinguishing the mullet species taxonomically and easy confusion with other mullet species in the catch prevents an understanding of their status. Based on the uncertainty in the status of its population in the UAE, and concerns for possible over-exploitation, it is listed as Data Deficient. Improvements in fisheries monitoring are needed.

Taxonomic notes and synonyms listed
The taxonomy of species in the Mugilidae family is complex and under revision (Durand and Borsa 2015). The family comprises of seven lineages which radiated early on, and many of its genera are paraphyletic or polyphyletic (Durand et al. 2012).This species has many synonyms, with over 280 specific names having been assigned to mullets of the Mugilidae family (Thomson 1997). There is a long history of confusion between the populations assigned these names (Ogilby 1908), and many of these have now been recognised as synonyms in the past 120 years (Thomson 1997).

Assessment rationale/justification
This inshore and estuarine species is not yet confirmed to occur in UAE Arabian Gulf waters, but has been detected in mullet fisheries catch on the Sea of Oman coast. It rarely occurs in the catch, and its population status there is very poorly understood. In addition, the difficulty in distinguishing the mullet species taxonomically and easy confusion with other mullet species in the catch prevents an understanding of their status. It is a commercially important species elsewhere in the Arabian Gulf, and overfishing is considered to have contributed to declines. In addition, habitat loss due to cessation of rivers and coastal development in the Gulf has also caused declines. The status of population(s) outside the UAE is not well-understood, but declines have been recorded in Kuwait, Iran and Bahrain. Little is known on its distribution and population status in UAE waters; therefore, it is listed as Data Deficient. Improvements in fisheries monitoring are needed.

Habitat details as listed in assessment
This species inhabits inshore waters and ascends rivers for feeding (M. Almukhtar pers. comm. 2014). It consumes detritus, algae, and small benthic invertebrates (Carpenter et al. 1997). It spawns from December to May in the Arabian Gulf, with a peak in December and the mean length at 50% sexual maturity is 15.4 cm (Elahi et al. 2012). The maximum length is 20 cm (Carpenter et al. 1997), age at first reproduction is about 2 years (Hakimelahi et al. 2010) and maximum age is about 5 years (M. Al-Husaini pers. comm. 2014). When applying an age at first reproduction of 2 years and longevity of 5 years, its estimated generation length is 3.5 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction -“ age at first reproduction)/2.
Threats listed in assessment
Major threats to this species in the Arabian Gulf include overfishing and habitat loss due to cessation of rivers and coastal development (E. Abdulqader, F. Kaymaram, J. Bishop, K. Al-Khalaf, M. Al-Husaini, M. Almukhtar, Q. Alghawzi, S. Alam, and S. Hartmann pers. comm. 2014).

Assessment rationale/justification
The Oman Cownose Ray occurs throughout UAE coastal waters, and may be common there. Due to confusion with the Javanese Cownose Ray (Rhinoptera javanica), population data can be uncertain, but it is suspected this species is the more common of the two that occur in the Arabian Sea region. Serious declines in cownose ray landings have been observed in Pakistan, and of batoids in general in India. It exhibits slow life history characteristics including low fecundity and a low annual rate of population increase. Considering this, the species has a low capacity to recover from even moderate levels of exploitation. It is especially susceptible to exploitation (target and bycatch) in many largely unregulated gill net 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, it is suspected to have declined by at least 30% over the past three generation lengths, or about 30 years. There is no information to confirm that this species is breeding in the UAE and no information confirming the likelihood of a cease in immigration from outside the region, despite ongoing threats and recorded declines. It is listed as Vulnerable A2d.

This species is benthopelagic over the continental shelf, often close inshore, usually forming very large aggregations (Last et al. 2016). It reaches at least 90 cm disc width (DW) (Last et al. 2016). Litter size is 1 pup per litter (R. W. Jabado unpubl. data), but it is unknown if reproductive periodicity is annual or biennial. Generation length is estimated to be ~10 years based on the larger (110 cm DW) R. bonasus (Fisher et al. 2013).
Threats listed in assessment
This species has been impacted by fisheries in the UAE and across its broader range. Marine habitats in the Arabian Gulf region have experienced high levels of disturbance and are quickly deteriorating due to major impacts from development activities (Sheppard et al. 2010).

Taxonomic notes and synonyms listed
The Leopard Whipray (Himantura leoparda) is a recently described (2008) species closely related and similar in shape and dorsal disc pattern to the Reticulate Whipray (H. uarnak) and Honeycomb Whipray (H. undulata). These three species are in the “uarnak' species-complex, a subgroup of mainly reticulated, ocellated or spotted whiprays. The Leopard Whipray can be distinguished by its unique arrangement of midscapular denticles and the leopard-like markings on the dorsal surface of adults and large specimens. Juveniles of the three species are born at different sizes and vary slightly in colour patterns and denticle shapes (Manjaji-Matsumoto and Last 2008, Last and Stevens 2009). Taxonomic work is currently ongoing to more clearly define the sister species relationships (P. Last pers. comm. 2010).Previously, this species has been misidentified as Dasyatis uarnak: Wallace 1967; Himantura fava: Compagno and Roberts 1982; Himantura sp. 1: Gloerfelt-Tarp and Kailola 1984; Himantura uarnak: Compagno 1986, Compagno et al. 1989; and Himantura undulata: Last and Stevens 1994, Last and Compagno 1999, White et al. 2006.

Assessment rationale/justification
The Leopard Whipray occurs throughout UAE coastal waters. This species is not targeted or valued in markets of the UAE, trawling has been banned there since 1980 and recently conducted surveys indicate it remains common in the area; however, Himantura species are discarded from catches in the UAE and it is unknown how this impacts the species. A large part of the species distribution in the Arabian Sea region (namely, India and Pakistan) is under extremely intense and increasing demersal fishing pressure. In contrast, Himantura species are regularly discarded in the Arabian Gulf and Sea of Oman, and they remain common there. 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. Given the intense fishing pressures faced by this species in other parts of the broader Arabian Seas region, and ongoing threats from discard and habitat loss in the UAE, it is inferred that declines reported in the Arabian Seas are representative of the status in the UAE. Based on recorded levels of exploitation and decline in habitat quality, it is suspected to have declined by at least 30% over the past three generation lengths, or about 60 years. It is listed as Vulnerable A2cd.

The Leopard Whipray is demersal on soft substrates and is mainly inshore and coastal, though it also occurs on the continental shelf to at least 70 m depth (White et al. 2006, Manjaji-Matsumoto and Last 2008). Himanura species exhibit a strong association with shallow waters of the western region where complex habitats such as coral assemblages and seagrass beds are most prevalent (Last et al. 2016 Rays of the World book). The biology of this species is poorly known, partly due to confusion with other species of the “uarnak' species-complex, especially the Reticulate Whipray (H. uarnak) and the Honeycomb Whipray (H. undulata) (Last and Stevens 2009). It attains about 140 cm disc width (DW); born at about 20 cm DW; males mature at 70-“94 cm DW (White and Dharmadi 2007, Last and Stevens 2009). Its reproduction is viviparous (White et al. 2006). It typically has1-4 young and reproduces year-round (Rastgoo et al. 2015). As there is no information on this species' maximum age and age at maturity, generation length was inferred as 20 years based on data for the congener, the Blackspotted Whipray (Himantura astra). Female Blackspotted Whiprays are reported to have a maximum age of 29 years and an age at maturity of nine years (Jacobsen and Bennett 2011). These were used to calculate a generation length of 19 years based on the equation: generation length = 9+((29-9)/2). The maximum size of the Leopard Whipray is considerably larger (~140 cm DW) than that of the Blackspotted Whipray (80 cm DW) so it is possible the generation length of the Leopard Whipray is greater than 20 years.
Threats listed in assessment
Information pertaining to threats specific to the UAE are unavailable. This species is impacted by bycatch fisheries that are active elsewhere in its range. Marine habitats in the Gulf are experiencing high levels of disturbance and quickly deteriorating due to major impacts from development activities (including dredging and reclamation), desalination plants, industrial activities, habitat destruction through the removal of shallow productive areas and major shipping lanes (Sheppard et al. 2010).

Assessment rationale/justification
This inshore, reef-associated species occurs throughout UAE waters, but is naturally uncommon to rare on the Arabian Gulf coast. It is easily confused with Pomadasys argenteus. Population data from the UAE are limited. Anecdotal information indicates some level of decline may have occurred on the eastern coast. It is heavily exploited in parts of the Arabian Gulf and Sea of Oman, and declines have occurred in at least Kuwait and Iran, although it remains abundant off Iran. The status of population(s) outside the UAE are not well-understood, though declines have been reported from Kuwait and Iran. Estuarine degradation may also impact this species. Based on the uncertainty regarding the population trend of this exploited species, it is listed as Data Deficient in UAE waters. Improvements in fisheries monitoring are needed.

Habitat details as listed in assessment
This speciesinhabits coastal rocky and coral reefs (Valinassab et al. 2011). Juveniles also occur in turbid inshore waters and estuaries, including mangrove habitats over sand and mud bottoms (Van der Elst 1993). Its maximum total length is 80 cm, but occurs more commonly to 45 cm (McKay 2001). Its maximum age is 36 years (Al-Husaini et al. 2001). Itspawns from February to July (Al-Husaini et al. 2001) and forms shoals near river mouths during the winter.
Threats listed in assessment
Fishing is causing declines in some areas of the Arabian Gulf and Sea of Oman, and may represent a major threat. It can also be impacted by estuarine degradation, a habitat that juveniles are dependent on, especially where freshwater flow has been altered (e.g., Kuwait; Al-Husaini et al. 2015). 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).
