Justification:
Figaro boardmani is a small, apparently common, but little known catshark found endemic to southern Australian waters between southeastern Queensland and Western Australia. It is demersal on the outer continental shelf and upper slope. Little is known of its biology. It is of only minor importance to fisheries, but is regularly taken as bycatch in various demersal trawl fisheries. The species is widespread in southern Australian waters with a wide bathymetric range and there appear to be no major threats to this species at present.

Geographic Range [top]

Range Description: Figaro boardmani is endemic to the Indo-West Pacific in temperate to subtropical waters of southern Australia, ranging from Noosa, southeastern Queensland to Carnarvon, Western Australia, and including the waters of New South Wales, Victoria, Tasmania and South Australia (Last and Stevens 1994, Compagno and Niem 1998). This species occurs primarily in the Eastern Indian and Southwest Pacific Oceans but also extends into the Western Central Pacific.

Habitat and Ecology [top]

Habitat and Ecology: Figaro boardmani is demersal on the outer continental shelf and upper slope and is reported in depths of 128 to 823 m (Last and Stevens 1994, Compagno and Niem 1998), however, it has been trawled from shallower waters (85 m) off southeastern Queensland (personal observation). It reaches 61 cm total length (TL), with males maturing at about 40 cm TL and females at about 40 to 43 cm TL and is reported to feed mainly on fish, crustaceans and cephalopods (Last and Stevens 1994, personal observation). The species is oviparous with one functional ovary in females. Of four mature females dissected from southeastern Queensland from the month of July three contained a single egg case in the left oviduct while the fourth contained an egg case in each oviduct. All possessed numerous large ovarian ova. Egg cases measured 68 to 74 x 19 to 21 x 8 to 9 mm (length x width x depth) (personal observation). Little else is known about its biology, with no other available information on reproductive biology, age and growth, natural mortality or behavioural ecology, except that it appears to sometimes aggregate by sex (Last and Stevens 1994). The species may not have a well-defined reproductive season, similar to the situation with other scyliorhinid sharks.

Threats [top]

Major Threat(s): Figaro boardmani appears to be widespread and common, is not targeted by commercial fisheries and is only of minor importance to fisheries at present through retention as bycatch (Last and Stevens 1994, Compagno and Niem 1998). The species is reported to be retained in the Western Australian Deep Water Trawl Fishery, although the quantity is unknown (Rose and SAG 2001). However, it is a frequent component of bycatch in demersal trawl fisheries (Last and Stevens 1994). It is discarded in the South East Trawl Fishery (SETF), which operates in southern Australian waters from New South Wales to South Australia (Rose and SAG 2001). In the SETF catch rates from an observer program have been stable over the last 10 years (Terry Walker, personal communication). In bycatch surveys of the eastern king prawn sector, deepwater component of the Queensland East Coast Trawl Fishery, F. boardmani was the third most commonly caught elasmobranch, although numbers were low and survivorship from trawling was high (Kyne, unpublished data). Post-release survivorship is unknown. It is probable that the species is also a component of bycatch of other demersal trawl fisheries operating in its distribution.

Conservation Actions [top]

Conservation Actions: There are currently no management measures in place for this species. Due to its bathymetric distribution it is unlikely to occur inside any marine protected areas, with the exception of the Commonwealth managed Great Australian Bight Marine Park.
