The Rosy Dory is widely distributed in the Atlantic and Pacific Oceans. It is a meso-benthopelagic species that occurs over the continental slope. This species is considered to be relatively common. It is taken as bycatch in deep trawl fisheries, however, it is not utilized. There are no major threats. It is listed as Least Concern.

Geographic Range [top]

Range Description:In the western Atlantic, Cyttopsis rosea is found in Canada (Scott and Scott 1988) to the southeastern USA, in the northern Gulf of Mexico and in the western Caribbean (Robins and Ray 1986). It can also be found off the northern coast of South America (Cervigon et al 1992). This species is also found in the eastern Atlantic, from the Bay of Biscay and the British Isles, around the South African coast to Natal, including Madagascar. In the Indian Ocean, it is found off the coast of Somalia (Sommer et al. 1996) and off the southwest coast of India. This species also occurs in the Indo-West Pacific and the Arabian Sea (Jawad et al. 2011, Heemstra in press). In the western Pacific, it is found off Japan, eastern and western Australia (Paxton et al. 1989) and New Zealand (Paulin et al. 1989). It is usually found between the depths of 100 and 600 m (Heemstra 2002).

Population [top]

Population:Cyttopsis rosea is thought to be relatively common (Heemstra 2002). Between Panama and Honduras in 2011, this species was relatively common with up to dozens in 30 min trawls (Robertson pers. comm. 2013). This species is common in Colombia (Acero and Polanco pers. comm. 2013). Based on a survey conducted in the Colombian Caribbean Sea the frequency of occurrence, abundance and biomass for Cyttopsis rosea were 75.93%, 1.29% and 0.67% respectively (Paramo et al. 2012). This species does not occur in abundances sufficient enough to support a fishery (Heemstra in press). In the eastern central Atlantic this species was uncommonly captured in the Nansen Surveys off West Africa (Iwamoto pers. comm. 2013).

Current Population Trend:Stable

Habitat and Ecology [top]

Habitat and Ecology:Cyttopsis rosea occurs frequently on the continental slope, often in mesopelagic, large schools (Hoese et al. 2006). It inhabits seamounts including the Bear Seamount (Moore et al. 2003) and Great Meteor Seamount (Uiblein et al. 1999) and knolls (Bailly 2012). It feeds mostly on other fishes and swimming decapod crustaceans (Quero 1986). The maximum length for Cytopsis rosea is 22 cm (Heemstra 2002). This species is meso-benthopelagic over the continental slope (Iwamoto pers. comm. 2013).


Use and Trade [top]

Use and Trade: Cyttopsis rosea is usually caught near the bottom with trawls. The flesh of C. rosea is considered to be of excellent quality but this species is too small and not abundant enough to be an important fishery resource (Heemstra in press).

Threats [top]

Major Threat(s): There are no known threats towards this species.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measure for this species.
