Justification:
The Bigeye Cigarfish occurs in the Caribbean, as well as the equatorial and central waters of all the oceans. This species plays an important trophic role and is a major prey item for tunas, billfishes and marine mammals. It is not of interest to fisheries and there are no known threats to this species. It is listed as Least Concern.

Geographic Range [top]

Range Description:Cubiceps pauciradiatus occurs in the Caribbean, as well as the equatorial and central waters of all the oceans (Haedrich 2002). In the western Atlantic, it is found from Nova Scotia to Florida, USA and the Gulf of Mexico to Argentina. (Cervigón 1994). This species is found from Mauritania to South Africa in West Africa (T. Iwamoto pers. comm. 2013). This species is found in depths of 58 to 1000 m (Cervigón 1994).

Population [top]

Population:This species is common (Collette pers. comm. 2013). There are 818 occurrence records and 268 museum records for Cubiceps pauciradiatus (Froese and Pauly 2011, www.fishnet2.net 2012) and lots typically contain one to two individuals, although several lots contain over 10 individuals. Salekhov (1989) showed that the largest catches of C. pauciradiatus occurred in tropical waters along the periphery of cyclonic gyres, the Equatorial Counter Current, and the upwelling region of the Sierra-Leone Ridge. The Gulf of Mexico may support a large subpopulation of this species because of the tendency for C. pauciradiatus to be abundant around the edges of gyres and upwelling areas (Lamkin 1997). Cubiceps pauciradiatus is one of the ten most abundant species in the plankton of the eastern tropical Pacific Ocean (Ambrose et al. 2002). This is a common and abundant species off of West Africa according to the Nansen Surveys (Iwamoto pers. comm. 2013).
Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:The maximum length for Cubiceps pauciradiatus is 20 cm (Haedrich 2002). It is a major prey item for tunas, billfishes and marine mammals in the tropical Indian Ocean (Potier et al. 2008). The trophic importance of this species has also been observed in the eastern Atlantic (Ménard et al. 2000, Bard et al. 2002).  The lifespan for C. pauciradiatus is one to two years and peak spawning occurs from December to April in tropical waters (Lamkin 1997). Juveniles remain in the top 100 m at night and C. pauciradiatus found in the upper layers move to depths of 200-300 m during daytime in the tropical Indian Ocean (Salekhov 1989). The have been recorded down to 1,000 m (Cervigon 1994). The preferred habitat and probable spawning area for C. pauciradiatus is associated with sharp temperature gradients associated with the Loop Current in the eastern Gulf and to anticyclonic-cyclonic rings in the western Gulf of Mexico (Lamkin 1997). Juveniles are found in the surface of Sargassum.
