The Black Spotted Catshark (Aulohalaelurus labiosus) is endemic to shallow coastal habitats and offshore reefs of temperate southwestern Australia. It is poorly known but it is reported to be common within its habitat. Although it has a limited range in coastal waters, it is not subjected to any significant fishing pressure due to its reef-dwelling and nocturnal habits and is of no commercial value to fisheries. However, there is evidence that this catshark has entered the marine aquarium trade, harvest levels of which should consequently be monitored to ensure future sustainability. With no major threats to the species at this time, it is assessed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:This catshark is a common, endemic, inshore species on the temperate Western Australian continental shelf, found in shallow coastal habitats and on offshore reefs (Last and Stevens 2009). It occurs to a depth of at least 4 m (Ebert et al. 2013). It is nocturnal but its biology is virtually unknown. It is oviparous, and attains at least 67 cm total length (TL), with adult males mature at approximately 54 cm TL (Last and Stevens 2009).

Use and Trade [top]

Use and Trade: There is evidence that this small, attractively spotted catshark enters the marine aquarium trade with several having been observed in aquarium retailers in Western Australia and it is possible that this may extend to elsewhere (W. White, pers. obs.).

Threats [top]

Major Threat(s): There is very little fishing pressure within this species' range and habitat and it is of little or no commercial value, although it is possible that it is a bycatch of some commercial and recreational fishing activities. The evidence of this catshark entering the marine aquarium trade (see Use and Trade section) indicates the potential for overexploitation if this type of harvesting is not carried out sustainably. At present, there are no estimates of the effect of this industry.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place. Species composition data from fisheries and from collectors for the aquarium trade in southwest Australia are required to ensure sustainable harvesting. All sharks and rays are commercially protected under Western Australian law. This regulation essentially restricts the retention of all shark and ray products by commercial fishing vessels other than those operating in the State's managed shark fishery.
