Benthosema pterotum has been assessed as Least Concern. Although this species is harvested as a food source, at present it is only of minor commercial importance to fisheries and the harvesting of this species is not likely to occur throughout its broad distribution. This species is reported to be the most dominat fish species in areas of its range and at present there is no reports of this species suffering any significant population declines. Due to the potential for increased exploitation of Benthosema pterotum, monitoring of the harvest levels and extent of harvest of this species is needed to determine if this threat is likely to become more widespread tin the future.

Population [top]

Population:The mesopelagic fish community in the Gulf of Oman is reported to be dominated by Skinnycheek Lanternfish (Dalpadado and Gjøsæter 1988). An estimate of the biomass in the Gulf of Oman ranges from 1- 4 million tonnes (Valinassab, Pierce and Johannesson 2007).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The Skinnycheek Lanternfish, Benthosema pterotum, is a benthopelagic and mesopelagic species that is typically found on the edge of the continental slope and around islands. This species has a depth range of 10-300 m. During the day it is found at a depth of 130-300 m and at night it migrates up to a depth range of 10-200 m. It feeds mainly on copepods and various crustacean larvae.
Generation Length (years):0.5
Movement patterns:Full Migrant

Threats [top]

Major Threat(s): There is large potential for future commercial exploitation of this species for use as fish meal (Dalpadado 1988), however at present the trawling of this species is not economically viable (Valinassab, Pierce and Johannesson 2007).

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place, or needed, for Benthosema pterotum.
