Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2003
Date Assessed: 2003-04-30
Annotations:
Needs updating
Assessor(s): Kyne, P.M. & Cavanagh, R.D. (SSG Australia & Oceania Regional Workshop, March 2003)
Reviewer(s): Shark Specialist Group Australia & Oceania Regional Group (Shark Red List Authority)
Justification:
A small, little-known catshark reported from isolated records from northern Australia. Found on the continental slope in depths of 290 to 470 m. Galeus gracilis appears to be rare and nothing is known of its biology. Limited trawl fisheries operate in its area of occurrence, and while the species is of no commercial interest, bycatch levels are unknown. No information is available to assess the species beyond Data Deficient.

Habitat and Ecology [top]

Habitat and Ecology: Demersal on the continental slope in depths of 290 to 470 m. Maximum size at least 34 cm total length (TL). Nothing known of its biology.
Systems: Marine

Threats [top]

Major Threat(s): Area of occurrence off northwestern Australia subject to minor trawl effort from the Commonwealth managed Western Trawl Fishery. While it is appears to be a rare species, it is of no commercial value and therefore unlikely be to subjected to any directed fishing pressure. Bycatch levels are unknown.

Conservation Actions [top]

Conservation Actions: None. The species is rare and research is required to obtain information on distribution, biology and fisheries interactions.
