Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Smale, M.J. (SSG Subequatorial Africa Regional Workshop, September 2003)
Reviewer(s): Cavanagh, R.D., Kyne, P.M. & Fowler, S.L. (Shark Red List Authority)
Justification:
A poorly known southern African endemic skate known from Namibia and South Africa. Its depth range (300 to 1,000 m), relatively wide distribution and common occurrence suggest that it is not yet threatened by commercial trawling. However, the situation must be monitored, particularly given the potential threat of expanding deepwater trawl fisheries in the region.
