Assessment Information [top]

Red List Category & Criteria: Least Concern 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): Seret, B. & Fowler, S. (Shark Red List Authority)
Justification:
A small lantern shark currently recorded from off northwestern Western Australia on the continental slope, with the possibility of occurrence off Java, Indonesia. Although the species is known only from a few small localities, further exploratory trawls may indicate a wider distribution. Etmopterus fusus is assessed as Least Concern because there is little fishing in its known area of occurrence off Western Australia. However, deepwater trawl fisheries are expanding globally, including in Indonesian waters where its potential area of occurrence and depth range are heavily fished. These activities may place future pressure on this small species and if it is verified from the waters off Java, a higher category (of at least Near Threatened) should be considered.

Habitat and Ecology [top]

Habitat and Ecology: Recorded from the continental slope in 430 to 550 m off Australia and possibly in 120 to 200 m off Indonesia (if it occurs off Java). Maximum size at least 30 cm total length (TL). Observed males of 25.1 to 25.8 cm TL are mature. Nothing else known of its biology.
Systems: Marine

Threats [top]

Major Threat(s): Presently only minor fishing activity in area of occurrence off Western Australia (Commonwealth managed North West Slope Trawl Fishery). The species is not targeted off Western Australia, and if captured is likely discarded (although survival rates are unknown and likely to be low from trawl captures). If the species occurs off Java, Indonesia, that area is likely to be subject to heavy trawling effort by Indonesian vessels (generally operating in less than 200 m depth which overlaps with the suspected depth range of the species off Java of 120 to 200 m). Quantitative data on Indonesian fisheries is required to assess its status in these waters if it is confirmed to be present there. Furthermore, given the global expansion of deepwater trawl fisheries additional pressure may be placed upon small and medium-sized etmopterid species in the future.
