The Australian Sawtail Shark (Figaro boardmani) is a small (61 cm total length), apparently common, catshark endemic to southern Australian waters between southeast Queensland and Western Australia. It is demersal on the outer continental shelf and upper slope at depths of 130–640 m. It is of only minor importance to fisheries, but is a regular discarded bycatch in various demersal trawl fisheries. A minor decline in catch rates has been documented in heavily fished areas of southeast Australia, while elsewhere catch rates have been stable. An oviparous species, it is likely to be productive. The species is widespread in southern Australian waters with a wide bathymetric range, and the population likely finds refuge in unfished areas. On this basis it is assessed as Least Concern, but with the caveat that catch rates should be monitored in heavily fished areas.

Geographic Range [top]

Range Description:The Australian Sawtail Shark is endemic to the Indo-West Pacific in temperate to subtropical waters of southern Australia, ranging from Noosa, southeast Queensland to Carnarvon, Western Australia, and including the waters of New South Wales, Victoria, Tasmania and South Australia (Compagno and Niem 1998, Last and Stevens 2009).

Habitat and Ecology [top]

Habitat and Ecology:The Australian Sawtail Shark is demersal on the outer continental shelf and upper slope at depths of 130 to 640 m (Last and Stevens 2009, Kyne et al. 2011). It reaches 61 cm total length (TL), with both sexes maturing at about 40 cm TL (Last and Stevens 2009, Kyne et al. 2011). The reproductive mode is single oviparity (carrying only one egg case in each uterus at a time) with one functional ovary in females; observed ovarian fecundity (the number of vitellogenic follicles) is 9–13 (Kyne et al. 2011). Reproductive seasonality is unkown (Kyne et al. 2011), although it may not have a well defined reproductive season, similar to the situation with other scyliorhinid sharks. It appears to sometimes aggregate by sex (Last and Stevens 2009).

Use and Trade [top]

Use and Trade: Sometimes retained as byproduct.

Threats [top]

Major Threat(s): The Australian Sawtail Shark is not targeted by commercial fisheries and is only of minor importance to fisheries at present through retention as byproduct. However, it is a frequent component of discarded bycatch in demersal trawl fisheries across its range.

The species is retained in the Western Australian Deepwater Trawl Fishery, although the quantity is unknown (Rose and SAG 2001). It is discarded in the Southern and Eastern Scalefish and Shark Fishery where it is regularly caught by otter trawlers (Walker and Gason 2007). Catch rates recorded in two regions covered by this fishery during an observer program were stable in one (southern Australia; 2000-06), and showed a minor but significant decline in the other (southeast Australia; 1988-2006).

In bycatch surveys of the eastern king prawn sector (deepwater component) of the Queensland East Coast Trawl Fishery, this shark was the third most commonly caught elasmobranch, although numbers were low and survivorship from trawling was high (Courtney et al. 2014). Post-release survivorship is unknown.

Conservation Actions [top]

Conservation Actions: Currently there are no management measures in place for this species. It is likely to occur in a number of new Commonwealth Marine Reserves. Given a minor decline documented off southeast Australia (Walker and Gason 2007), catch levels should continue to be monitored in the Southern and Eastern Scalefish and Shark Fishery through observer programs.
