The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Assessment rationale/justification
In UAE waters, the Oman Guitarfish occurs only in the Sea of Oman. It is a poorly-known, relatively recently described species with a global distribution that is apparently restricted to inshore waters of the Sea of Oman. A total ban on fishing for this species has been in place in the UAE since 2019. It has been taken in fisheries in the past at an unknown level. Little is known on its distribution, population, ecology and potential major threat from fishing; therefore, it is listed as Data Deficient in the UAE.

Habitat
Habitat details as listed in assessment
Little is known about this species' habitats, but it is presumed to occur over soft substrates. A male was mature at 50 cm total length (TL) and three adult females were 58-60 cm TL (Last et al. 2016a), indicating this is a small species. There are no reproductive or age data available. Generation length is inferred to be 5 years from the Lesser Guitarfish (Acroteriobatus annulatus) from southern Africa (Compagno et al. 1989).
Threats and conservation measures listed
Threats listed in assessment
The direct threats are unknown for this species, but similar species are known to be impacted by high levels of largely unmanaged and unreported mortality in target and bycatch fisheries.
