Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2009
Date Assessed: 2007-01-01
Assessor/s: Cronin, E.S.
Reviewer/s: Valenti, S.V. & Fowler, S.L. (Shark Red List Authority)
Justification:
The Quagga Catshark (Halaelurus quagga) is a very poorly known, small demersal catshark occurring in tropical offshore waters of the Somalian and Indian continental shelf in the western Indian Ocean. Occurs at depths of 54?186 m. The biology of this species is largely unknown, but it reaches a maximum size of about 35 cm TL. It is a potential bycatch of demersal trawl and other demersal fisheries operating within its range, but no specific details are available. Insufficient information is available to assess this species beyond Data Deficient at present. Research is required on this species' abundance, full distribution and capture in fisheries.

Habitat and Ecology [top]

Habitat and Ecology: A little known catshark preferring the tropical offshore waters of the continental shelf and found on or near the bottom at depths of 54?186 m (Compagno 1984). The biology of this species is largely unknown, but size at birth is ~8 cm total length (TL), males mature at 28?35 cm TL and it reaches a maximum size of about 35 cm (Compagno 1984).
Systems: Marine

Threats [top]

Major Threat(s): This species is presumably taken as bycatch in demersal trawl and other demersal fisheries operating within its range, although no specific information is available. Demersal fishing pressure is very intensive off India and Somalia but little information is currently available on the elasmobranch catch (Young et al. 2006).

Conservation Actions [top]

Conservation Actions: No management or conservation efforts are currently in place. Research is required on this species? occurrence, life-history parameters, capture in fisheries and population trends.

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.
