Northwest and western central Pacific: Japan (Northeastern Honshu, Shikoku, and Okinawa), Taiwan, northern Papua-New Guinea and Indonesia (Compagno in prep, W. White pers. obs. 2007).
Taxonomic revision of Centrophorus is currently underway and may reveal that more than one species is involved across the distributional range.

This species is also caught in bottom trawls off Taiwan. No part of the catch is discarded in Taiwan (B. Séret pers. comm. 2006) and individuals are probably also used in the production of fishmeal.
No information is available on the interaction of this species with fisheries throughout its range in the Indian Ocean. Industrial deepwater fishing for lobsters is reported off Somalia, perhaps down to 400 m, but the gear type is not reported and no data are available from the fishery. In the mid-1970s, deep-sea trawling was carried out by SOMALFISH, a Somali/USSR joint venture commercial fishing company off Somalia and since then several foreign fishing companies have been given fishing licenses to fish in the offshore EEZ of Somalia (FAO 2007a).
There are also an estimated 700 foreign-owned vessels that are fully engaged in unlicensed fishing in Somali waters (FAO 2007a). This illegal, unregulated, and unreported (IUU) fishing occurs offshore, as well as in the inshore (FAO 2007a). This makes it impossible to monitor total fishery production and the state of the fishery resources they are exploiting (FAO 2007a). There is also strong suspicion of illegal dumping of industrial and nuclear wastes along the Somali coast (FAO 2007a).
Little is known about deepwater fisheries operating off India at present. There were apparently 100 deep-sea fishing vessels in operation off India during 2004 (FAO 2007b). Marine fish production from near shore waters off India has reached almost a plateau and it is likely that fisheries will develop to exploit deeper waters off shore pelagic species further (FAO 2007b).
The threatened status of this species is uncertain, but of concern because of local deepwater fisheries, little knowledge of its biology, and its restricted distribution (Compagno in prep). Given the biological vulnerability of this genus and the rapid population declines observed in other exploited Centrophorus species (for example Centrophorus harrissoni), any bycatch is of concern. There is a need to collect species-specific catch data throughout this species' range, to assess the impact of fisheries on this species.
Dwarf gulper shark
The dwarf gulper shark, Centrophorus atromarginatus, is a dogfish of the family Centrophoridae found in the Indo-West Pacific oceans, from the Gulf of Aden, Japan, Taiwan, and northern Papua New Guinea.
