|Taxonomic Notes:||This species is also reported from Lake Turkana under the old name Alestes nurse (Rüppel, 1832). Turkana specimens of this species are noticeably smaller (12 cm fork length) than specimens from other populations, which grow up to 218 mm SL. Therefore the Turkana population was described as a distinct subspecies (Seegers et al. 2003), however Brycinus nurse nana is not a valid subspecies.|

This species has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. It has also been assessed regionally as Least Concern for eastern Africa. Due to uncertainty of this species distribution, it has been assessed as Data Deficient for northern and north eastern Africa. In the central Africa regional assessment it has been categorised as Not Applicable as it is thought that less than 5% of this species range falls within this region.
|Range Description:||This species is wide spread across much of Africa, from Senegal to Ethiopia, from Egypt to Democratic Republic of Congo.
Central Africa: In Lower Guinea, it is known from the Cross and Meme basins.
Eastern Africa: This species is found in Lake Albert, the Albert and Murchison Niles, and the Aswa River system (This species is known from upper Nile system). It is also present in Lake Turkana
Northern Africa: It is present in the upper Egyptian Nile and Lake Nasser (also known as Lake Nubia)
Northeast Africa: This species is found in the Ghazal and Jebel systems, White and Blue Niles, and Nile to Lake Nasser.
Western Africa: It is widely distributed in the Nile, Chad, Niger (including the Benue river), Ogun, Ouémé, Mono, Sio, Volta, Bia, Comoé, Agnébi, Bandama, Sassandra, Konkouré, Gambia, Tominé (Corubal) and Senegal basins.

|Population:||Little information available.|
|Habitat and Ecology:||Brycinus nurse is a pelagic, potamodromous species. It inhabits rivers, lakes, irrigation canals and fringing vegetation. It feeds on zooplankton, Caridina, insects, snails and vegetation (Bailey 1994), and less frequently small fishes mainly Haplochromis spp. Dwarf populations are described in lake basins. It spawns at the beginning of the rainy season.|
|Major Threat(s):||Populations of this species are threatened by heavy commercial fishing pressure for the aquarium trade. In northern Africa, dams, water pollution (agriculture, domestic and commercial/industrial), groundwater extraction and drought all pose possible threats.|
|Conservation Actions:||No information available. More research is needed into this species population numbers and range, biology and ecology, habitat status and threats, as well as monitoring and potential conservation measures.|
