The depth distribution of the species may lie within the range of fisheries in Japan, Taiwan and possibly Indonesia. It is a rare and inedible species in Japan (H. Ishihara pers. comm. 2006) and is therefore not targeted, but may potentially be taken as bycatch and possibly utilized for liver oil. In eastern Indonesia, deepsea longline fisheries operate from 150â600 m with the majority of fishing occurring in depths of less than 300 m (White et al. 2006). Commercial prawn trawlers are known to land substantial catches of elasmobranchs as bycatch. So far trawling is restricted to shallower water, however according to White et al. (2006), in the future, trawl methods may be adopted in deeper water, especially if foreign fishing vessels are allowed access to Indonesian waters. Future expansion of the deepsea fishery in Indonesia is highly likely, with the potential to rapidly deplete the vulnerable deepwater chondrichthyan fauna (White et al. 2006). The species has been found at greater depths off New Caladonia and Vanuatu. Deepwater fisheries are very uncommon in this region. Like other Etmopterus species, this species is not targeted, most likely discarded if caught, and unlikely to be caught frequently on large commercial fishing hooks.
