Taxonomic Notes: Previously reported as Mormyrops deliciosus (Leach, 1818), a junior synonym of M. anguilloides (see Bigorne, 1987). The taxonomic position of the kenyan population is uncertain: the species might be identical to M. citernii Vinciguerra, 1913 described from the Juba system in Somalia (Seegers et al. 2003).

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, eastern, north eastern, southern and western Africa.

Geographic Range [top]

Range Description:This species has a very wide distribution area and is present in most parts of sub-saharan Africa.

Central Africa: Mormyrops anguilloides is known from throughout the Congo River basin. Elsewhere, it is known from the Lower Guinea region, distributed in the Sanaga River basin, in the Nyong, the Lokoundjé and the Cross.

Eastern Africa: It is known from the Lake Albert basin, and Albert Nile, as well as from the Malagarasi River and Lake Tanganyika. It is also known from Lake Malawi. In Kenya it has been recorded from the Northern Ewaso Nyiro system (Seegers et al. 2004) but this is probably not correct. An uncertain record of M. anguilloides from the Athi River basin discussed by Okeyo (1998) is unsubstantiated (Seegers et al. 2004).

Northeast Africa: This species is present in the Ghazal and Jebel systems, White Nile, and the Blue Nile to Lake Nasser (also known as Lake Nubia). It also occurs in the Wabi Shebelle basin, Ethiopia.

Southern Africa: In southern Africa it is restricted to the middle and lower Zambezi and the Buzi and Pungwe Rivers (Skelton 2001).

Western Africa: M. anguilloides has a very wide distribution area and is present in the most parts of West African basins.

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a demersal, potamodromous species. This species inhabits rivers and river mouths. Juveniles are found in marginal habitats whereas adults prefer deep quiet water and estuaries away from strong currents (Tweddle and Willoughby, 1982). It also occurs beneath Salvinia mats and in river estuaries in Lake Kariba. Juveniles prey on invertebrates, mainly shrimps and insect larvae, whilst larger individuals feed on small cichlids, minnows and labeos. It breeds during the rainy season (Skelton 1993) and is a fractional spawner (Alberet 1982, Kirschbaum 1995).
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: This species is harvested for human consumption.

Threats [top]

Major Threat(s): In eastern Africa this species is threatened by fisheries and environmental disturbance. Intense fishing pressure with gill nets in certain areas of the lower Zambezi probably affects this species.

Conservation Actions [top]

Conservation Actions: Management of riverine fisheries is needed.
