Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2003
Date Assessed: 2003-04-30

Justification:
This dogfish occurs in eastern Australian waters. Its main known range is in an area with minimal fisheries although future expansion of deepsea trawl fisheries could pose a threat. The biology is virtually unknown though it is likely to have the limiting life history characteristics similar to other deepwater shark species. At present there is inadequate information to assess the conservation status of this species.

Geographic Range [top]

Range Description: This species was known as Squalus sp. B in Last and Stevens (1994). Found on the upper continental slope at depths from 240 to 450 m. Eastern Australia, from the upper continental slope between the Queensland Plateau off Cairns, to the Bermagui area, southern New South Wales. Range is currently uncertain.

Population [top]

Population: No data are available on population size or subpopulations.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This medium-sized dogfish is either rare or uncommon, and its biology is virtually unknown. It attains at least 65 cm, the smallest mature male examined was 62 cm.
Systems: Marine

Threats [top]

Major Threat(s): This species is not thought to be abundant off central and southern New South Wales (NSW), and their occasional capture in the NSW trawl fishery is unlikely to have much impact on the main population which is presumably to the north (K. Graham pers. comm.). Future development of deepsea trawl fisheries in this area could pose a threat, as it is susceptible to being caught as bycatch.

Conservation Actions [top]

Conservation Actions: Currently there are no conservation measures in place for this species.
