Assessment Information [top]

Red List Category & Criteria: Least Concern     ver 3.1
Year Published: 2010
Assessor/s: Bousso, T., Lalèyè, P., Marshall, B. & Tweddle, D.
Reviewer/s: Snoeks, J., Tweddle, D., Getahun, A., Lalèyè, P., Paugy, D., Zaiss, R., Fishar, M.R.A & Brooks, E.
Justification:
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 central and southern Africa. Within east Africa, it only occurs in the Lower Shire river in Malawi, and has therefore been assessed as Vulnerable (D2). In northeast and western Africa this species is only known from very few localities within a restricted range. More information is needed on the species distribution, threats and habitat, and it is therefore regionally categorised as Data Deficient.
History:
2006 – Least Concern (IUCN 2006)

Geographic Range [top]

Range Description: This species is known from lakes and river drainages in Chad, the Central African Republic, Sudan, Uganda, the Congo, northern and western Zambia, southeastern Angola, northeastern Namibia, northwestern Botswana and from the lower Shiré River in Malawi.

Central Africa: Aplocheilichthys hutereaui is found in the upper Kwango and Kasai systems, from the Ubangui and Uele River systems and from the upper Lualaba and Luapula systems.

Eastern Africa: In eastern Africa it is restricted to the Lower Shire river, Malawi.

Northeast Africa: This species is found in the White Nile and one or more affluent subsystems.

Southern Africa: It is present in the Okavango, This species is known from upper and Lower Zambezi (lower Shire) and Pungwe-Buzi systems near the coast (Skelton 2001). Also in the Zambian Congo and Luapula. In Zimbabwe, it has been also collected in the Middle Zambezi at the head of Lake Kariba (J.L. Minshull pers. comm.).

Western Africa: In western Africa, this species is only known from lakes and river drainages in Chad and northern Central African Republic.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This is a benthopelagic species, non-migratory species. It is found in small rivers, brooks, swamps and shallow lake parts among vegetated areas (Wildekamp et al. 1986). Strictly a floodplain or marsh-loving species (Skelton 1993). It is not a seasonal killifish (Huber 1996). It is difficult to maintain in aquarium.
Systems: Freshwater

Threats [top]

Major Threat(s): It is commercially targeted as an aquarium fish. In western Africa, there is possible declining habitat quality due to agricultural pollution and drought.

Conservation Actions [top]

Conservation Actions: The species has little protection other than reserves in the Okavango Delta. More research is needed into this species taxonomy, population numbers and range, biology and ecology, habitat status and threats, as well as monitoring of population trends.
