The Gulf Catshark (Asymbolus vincenti) is widely distributed across southern Australia. It appears to be most common in the Great Australian Bight, where demersal trawl effort is generally low across a large portion of its range. In the Southern and Eastern Scalefish and Shark Fishery it is an infrequent bycatch, and always discarded. This species is assessed as Least Concern due to its wide range and limited fisheries interactions.

Australia (South Australia, Tasmania, Victoria, Western Australia)

Habitat and Ecology [top]

Habitat and Ecology:This catshark has been reported from depths of 130–220 m in the Great Australian Bight, and mostly at depths less than 100 m off western Tasmania and Bass Strait; associated with seagrass beds near the coast in Bass Strait (Last and Stevens 2009). This species reaches at least 56 cm total length (TL) with males mature at 38 cm TL (Last and Stevens 2009). It is oviparous, otherwise the biology of this species is almost entirely unknown.

Use and Trade [top]

Use and Trade: This species is not likely to be utilized due to its small size; it is discarded when caught in the Southern and Eastern Scalefish and Shark Fishery (Walker and Gason 2007).

Threats [top]

Major Threat(s): This catshark is a discarded bycatch in the Southern and Eastern Scalefish and Shark Fishery in southern Australia at a low rate, mostly in the Great Australian Bight Trawl Sector; annual bycatch was estimated at 632 kg from 2000–2006 (Walker and Gason 2007). The fishery has decreased in fishing effort and number of operating vessels in recent years, and fishing effort is generally low across a large portion of the core (Great Australian Bight) distribution of the species (Georgeson et al. 2015, Moore and Curtotti 2015).

Conservation Actions [top]

Conservation Actions: Currently no conservation measures are in place for this species. It potentially occurs in the South-west Commonwealth Marine Reserves Network, however, the management plans for the network have not yet been implemented (as of February 2016).
