Pseudobathylagus milleri has been assessed as Least Concern.  This broadly distributed species has been described as common in areas of its range, and at present, it is unlikely to be impacted by any major threat processes.

Geographic Range [top]

Range Description:Pseudobathylagus milleri is known from Iwate prefecture in Japan to the Bering Sea, and from British Columbia to California (C. Mecklenburg pers. comm. 2008, A. Balanov pers. comm. 2008). Mecklenburg (pers. comm. 2008) states that it is also known from the Sea of Okhotsk.

Population [top]

Population:The larvae of Pseudobathylagus milleri have been found to be among the most abundant during April around the Kuroshio-Oyashio region of the western north Pacific (Sassa et al. 2006).  This species has been described as a common mesopelagic fish in the Bering Sea (Balanov and Il'inskiy 1992) and the northwestern Pacific off Kamchatka and Kurile Islands (Ivanov 1997).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Pseudobathylagus milleri is a mesopelagic/bathypelagic species during its adult life stage, with epipelagic/mesopelagic planktonic eggs and larvae (A. Balanov pers. comm. 2008). This species has a depth range of 0-6,600 m.

Threats [top]

Major Threat(s): Due to the deep-water nature of Pseudobathylagus milleri, it is unlikely that it is being impacted by any major threat processes.

Conservation Actions [top]

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

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.

Classifications [top]

10. Marine Oceanic -> 10.3. Marine Oceanic - Bathypelagic (1000-4000m)
10. Marine Oceanic -> 10.4. Marine Oceanic - Abyssopelagic (4000-6000m)
