Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2009
Date Assessed: 2007-07-07
Assessor(s): SSG Asia Northwest Pacific Red List Workshop, Valenti, S.V.
Reviewer(s): Séret, B. (Shark Red List Authority)
Justification:
This Indo-Pacific stingray’s distribution is not well known, but it probably ranges from Japan to India, possibly including the Philippines. Its habitat and biology are poorly known and it reaches a maximum size of 130 cm TL and 50 cm DW. It is presumably taken in demersal fisheries operating within its range, but no information is currently available on catches of this species. At present insufficient information is available on the species’ distribution, biology and capture in fisheries to assess it beyond Data Deficient. Further investigation is required and this assessment should be revisited in the near term.

Geographic Range [top]

Range Description: The distribution of this Indo-West Pacific stingray is not well known, but probably ranges from southern Japan to India, possibly including the Philippines (Compagno 1998, Compagno et al. 2005). One record from Trinidad possibly refers to another species (Compagno et al. 2005).

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The biology and habitiat of Bennett's Stingray (Dasyatis bennetti) are poorly known. The species reaches a maximum size of at least 130 cm total length (TL) and about 50 cm disc width (DW) (Compagno 1998).
Systems: Marine

Threats [top]

Major Threat(s): Bennett's Stingray is presumably taken in demersal trawl and net fisheries operating within its range, but no specific information is available on catches of this species. Ray fisheries are important in many areas of the western central Pacific, with substantial landings off Thailand and Singapore (Compagno 1998). Stingrays are also taken in various intensive demersal fisheries operating off India (Hanfee 1999).

Conservation Actions: No known conservation measures in place.
