This species has been referred to as Lutjanus aya by previous authors, but Rivas (1966) concluded that Bodianus aya is not a lutjanid, but probably a sciaenid.

Assessment rationale/justification
In UAE waters, this reef-associated species occurs only in the Sea of Oman, and is relatively uncommon there. It is exploited by fisheries off Oman, and it is not known if exploitation in the Sea of Oman is impacting the UAE population. Based on the uncertainty regarding the population trend of this exploited species, it is listed as Data Deficient.

Taxon distribution as listed in assessment
In UAE waters, this species occurs only in the Sea of Oman, and is apparently excluded from the Arabian Gulf. Although Grandcourt (2012) lists it as occurring in the Arabian Gulf, both Allen (1984, 1985) and Randall (1995) did not include the Gulf in its range. In addition, Field (2013) notes it only occurs around the Arabian peninsula. Globally, it is restricted to the Western Indian Ocean where it occurs from Somalia to the southern Red Sea to Pakistan, India and the Gulf of Mannar (Allen 1984, Allen 1985, Goren and Dor 1994, Zajonz et al. 2000, Manilo and Bogorodsky 2003, Wilkens 2005, Al-Jufaili et al. 2010, Golani and Bogorodsky 2010, Psomadakis et al. 2015, Joshi et al. 2016). Its depth range is 10 to 20 m (Lieske and Myers 1994, Manilo and Bogorodsky 2003, Wilkens 2005).

Habitat
Habitat details as listed in assessment
This species inhabits clear, coastal coral and rocky reefs. It occurs singly or in small groups (Allen 1985, Wilkens 2005). The maximum total length is 40 cm (Randall 1995, Field 2013). Along the southern Omani coast, it has a prolonged breeding season (August to March) with peak spawning occurring in October and January. The total length and age at first maturity is 28.1 cm and 2.9 yrs for males and 29.7 cm and 4.3 years for females and it has been aged up to 18 years (Al-Mamari et al. 2017). When applying an age at first reproduction of 4.5 years and longevity of 18 years, its estimated generation length is 11.25 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 and conservation measures listed
Threats listed in assessment
A potential threat from fishing is poorly understood. 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).
