| Taxonomic Notes: | The status of the northern Ewaso Nyiro population is uncertain (Seegers et al., unpublished). As presently recognised, it is a widespread species. There is geographical variation and it is perhaps a species complex. Taxonomic study is needed. |

Assessment Information [top]
| Red List Category & Criteria: | Least Concern ver 3.1 | |||
| Year Assessed: | 2010 | |||
| Assessor/s: | Bills, R., Cambray, J., Engelbrecht, J., Kazembe, J., Marshall, B. & Vreven, E. | |||

|
Justification: This species has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. There are some threats from poisoning but these are localised, and it has also been assessed regionally as Least Concern for eastern and southern Africa. |

| Population Trend: |
Unknown

Habitat and Ecology [top]
| Habitat and Ecology: | This species is usually found in vegetated, non- or slow flowing sections of rivers and river margins. Also found in marginal lagoons, isolated pans in floodplains. It feeds on small aquatic organisms, and food consists of diatoms, algae and invertebrates (Polling et al. 1992). It breeds in summer, possibly migrating to spawning sites (Skelton 1993). |
| Systems: | Freshwater |
Threats [top]
| Major Threat(s): | Fisheries pose a possible future threat, although reported to be of no importance in Lake Chiuta (Tweddle 1983). Marginal pools in the Niassa Reserve, Mozambique are routinely poisoned by local fishermen. These pools act as innocula for the main river system and are critical habitats for many species not suited to open water of main river channels. |
Conservation Actions [top]
| Conservation Actions: | Conservation of critical marginal lagoons by environmental education and law enforcement is needed. |
