Myctophum obtusirostre is a widespread species that is not facing any known threats, though it is occasionally taken as bycatch by deep-sea shrimp fisheries. More research on this species needs to be conducted to assess the population size and trend in the eastern Atlantic. This species is listed as Least Concern.

Geographic Range [top]

Range Description:In the eastern Atlantic, this species is found in the area between 22°N-11°S, but it is apparently absent in equatorial waters and in the eastern south Atlantic (Hulley and Paxton in press).

Population [top]

Population:There are little data regarding the population size of this species in the eastern Atlantic. However, it appears in moderate numbers in mid-water trawl surveys taken in other parts of its range (Sassa et al. 2004). It also appears in significant numbers as bycatch of deep-sea shrimp trawling in the Indian Ocean (Pillai et al. 2009).
Current Population Trend:Unknown
