The Quilon Electric Ray (Heteronarce prabhui) is a little known numbfish known only from the Arabian Sea, India, at around 300 m depth. Very little is known about the biology or ecology of this species. This species may be taken as bycatch in multi-species fisheries off India, but no details are available. Insufficient information is available to assess this species beyond Data Deficient at present. As this species has an apparently restricted range, research into its interaction with fisheries, full distribution and biology is a priority and it should be reassessed as this information becomes available.

Habitat and Ecology [top]

Habitat and Ecology:The holotype of this species was collected from a depth of 300 m (Eschmeyer 2007). The biology and habitat of this species are largely unknown (Compagno 1999).

Threats [top]

Major Threat(s): It is a potential bycatch of multi species fisheries using gears such as trawls and drift nets, but no catch data are available (Hanfee 1991). The apparently restricted range of this species may make it vulnerable to depletion.

Conservation Actions [top]

Conservation Actions: No management or conservation efforts are currently in place. Like many deepwater species, more information on biology, ecology, range and depth distribution and importance in fisheries are required to further assess status and any future conservation needs. If taken, catches require monitoring, particularly as deepwater fisheries expand worldwide.

The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all chondrichthyan species in the region.
