The Pale Catshark (Apristurus sibogae) is a rare deepwater catshark known only from the holotype, a juvenile female (21 cm TL) taken at 655 m depth in the Makassar Straits, between Borneo and Sulawesi, Indonesia. At present there is insufficient information to assess this species beyond Data Deficient. Surveys are required to gather further information on the biology and distribution.

Habitat and Ecology [top]

Habitat and Ecology:Known only from the holotype, a juvenile female measuring 21 cm total length (TL), taken at 655 m on the Makassar Straits slope (Nakaya 1989). The biology of this species is virtually unknown.

Threats [top]

Major Threat(s): There are currently no deepwater fisheries operating in the Makassar Straits (Fahmi pers. obs. 2007) where the holotype (and only known specimen) was taken. The species may have a wider depth distribution than currently known and any future fishing effort should be carefully monitored to ensure that this species is not adversely affected. It is apparently rare, has a restricted distribution and probably displays similar life history characteristics to other deepwater sharks (slow growth, late age at maturity, low fecundity). These factors may make this species particularly vulnerable to overfishing, should fisheries expand to such depths.

Conservation Actions [top]

Conservation Actions: No management or conservation efforts are currently in place. Like many deeper water species more information on biology, ecology and importance in fisheries are required to further assess status and any future conservation needs. Where taken, catches require monitoring, particularly as deepwater fisheries expand worldwide.
