Description
Found on the continental shelf, also in coastal waters. Feeds on crustaceans, fish, and cephalopods. Oviparous, with up to 16 egg-cases per female, hatching about a month after deposition (Ref. 5510). Not utilized at present but are being caught by sports anglers with rod and reel.

Found on the continental shelf and upper slope from the surfline to depths of at least 290 m. The type specimen was caught by a shore angler.
Males mature at 32 to 38 cm total length (TL), reaching at least 56 cm TL. Mature females range from 40 cm TL to at least 56 cm TL (Bass et al. 1975). Possibly oviparous, with the females carrying up to eight capsules in each uterus simultaneously. Size at birth approximately 8 cm TL. Pregnant females are caught along the KZN coast in late winter (July to September) (Bass et al. 1975).
In the Tugela Banks prawn trawl fishery, the catch ranged from 30 to 60 cm TL, with a mean of 40 cm TL and a mode of 30 to 50 cm TL (Fennessey 1994). It would appear that mature animals represent a large percentage of the catch.
This species feeds mainly on crustaceans, teleosts and cephalopods.

Justification
A small catshark of the continental shelf and upper slope (to 290 m) endemic to South Africa and Mozambique. This species is taken as a bycatch in the prawn trawl fishery on the Tugela Banks, on the inshore shelf off northern KwaZulu-Natal (KZN), South Africa. It was found in 18% of the trawls examined, with a 19% mortality rate, thus fishers should be encouraged to return the live sharks to the sea, especially as they are little utilised given their small size. The bycatch may constitute a threat, particularly as it includes large numbers of mature specimens with many of the females possibly being pregnant. Catch rates over a longer time period are needed to assess the status of this species, particularly to compare with the 1994 study in terms of catch trends and fishing pressure. No details are available of catches in the Mozambique prawn trawl fishery where it may also be caught as bycatch. Until further study it is not possible to assess this species beyond Data Deficient.

Conservation Actions
The bycatch in the KZN prawn trawl fishery may constitute a threat, particularly as the catch includes large numbers of mature specimens, with many of the females possibly being pregnant. The estimated annual catch for the period 1989?1992 was 1,071?2,021 at a mean catch rate of 0.16 individuals per hour. It was found in 18% of the trawls examined, with a 19% mortality rate (Fennessy 1994). Catch rates over a longer time period are needed to assess the status of this species. No details are available of catches in the Mozambique prawn trawl fishery where it may also be caught as bycatch.

Conservation Actions
At this stage the KZN prawn trawl fishery should be encouraged to release those animals found alive, which represents 80% of the catch.
