Red List Category & Criteria: Data Deficient ver 3.1

The Dwarf Black Stingray (Dasyatis parnonigra) is known from a small number of specimens caught in shelf waters (60–185 m depth) off northwestern Australia and Southeast Asia, where it is known from Indonesia, Malaysia and possibly the Philippines. This medium-sized (>51 cm disc width) species is caught incidentally in demersal trawl and trammel-net fisheries in Borneo and has been rarely recorded from gillnet fisheries in eastern Indonesia. The distribution of this poorly-known species through Southeast Asia is presently unclear. Batoids are subject to high fishing pressure throughout much of the known distribution of the Dwarf Black Stingray. Full assessment requires the collection of more data on the range and threats faced by the Dwarf Black Stingray and it is therefore assessed as Data Deficient.

Geographic Range [top]

Range Description: The Dwarf Black Stingray is known only from northwestern Australia, Indonesia and Malaysia; possibly also West Papua and the Philippines (Last et al. 2010). This may suggest a wider range through the Western Central Pacific (Last and White 2008).
Countries occurrence:
Australia (Western Australia); Indonesia (Bali); Malaysia (Sabah)
FAO Marine Fishing Areas:
Indian Ocean – eastern; Pacific – western central
Lower depth limit (metres): 185
Upper depth limit (metres): 60

Population [top]


The Dwarf Black Stingray is known from a small number of specimens. No information available on population size or trend. The Dwarf Black Stingray is a small (<0.1% of catch by number and biomass, respectively) component of batoid catches in eastern Indonesia (White and Dharmadi 2007).

Current Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology:

The Dwarf Black Stingray is demersal on insular and continental shelves in 60–125 m depth in Borneo (Last et al. 2010) and 125–185 m depth in northwestern Australia (Last and Stevens 2009). Attains a disc width (DW) of at least 52 cm; males mature at 35 cm DW (White et al. 2006, Last et al. 2010).

Systems: Marine

Use and Trade [top]

Use and Trade: The Dwarf Black Stingray is caught incidentally by the demersal trawl and trammel-net fisheries operating in shelf waters of Borneo, where it is used for its meat (Last et al. 2010). Caught rarely by the gillnet fisheries operating in shelf waters of eastern Indonesia, where it is also retained for meat (White et al. 2006). It is not utilized commercially in Australia.

Threats [top]

Major Threat(s):

Threats to the Dwarf Black Stingray are insufficiently known. Caught only from trawl surveys in Australian waters (Last and Stevens 2009). Caught incidentally by the demersal trawl and trammel-net fisheries operating in Borneo shelf waters (Last et al. 2010) and rarely in gillnet fisheries in eastern Indonesia (White et al. 2006). Large target fisheries for batoids exist through much of this species' range in southeast Asia (White and Dharmadi 2007), although the species has seldom been reported from catches.

Conservation Actions [top]

Conservation Actions:

Further clarification on distribution and habitat preferences of the Dwarf Black Stingray is required to evaluate threats. Market surveys through Southeast Asia would help to clarify the relative abundance of this species in catches.
