Justification: Although exact population estimates are not available, the species was rare in the past and the population has declined since the 1970s due to the introduction of the Nile Perch (Lates niloticus). Whilst many Haplochromis species suffered dramatic population crashes, many have shown signs of recovery in the last few years, however this species has not been seen since 1984. If it is still present it is likely to be extremely rare with very few individuals, but it may now be Extinct. |

| History: |
|
||||||
| Population: | In the 1970s this species was present in the Northern part of the Mwanza Gulf, but the population density was not known. The species was rarely caught (less than 4 times a year) and disappeared from the catches after 1984 and has not been observed since. |
| Population Trend: |
Decreasing
|
| Habitat and Ecology: | This species is found over all substrates in the littoral zone (along rocky shores, over sand and over mud), except vegetation. It is classified as a piscivore (sensu stricto). |
| Systems: | Freshwater |
| Major Threat(s): | The main threat to this species is hybridization due to decreased water transparency (on account of eutrophication and erosion leading to increased sedimentation and runoff) interfering with mate recognition visual cues (Mrosso et al. 2003). An additional threat is predation by Nile Perch (a potentially reversible threat). This species is fished, although not targeted specifically. |
| Conservation Actions: | Many fish species within Lake Victoria have suffered severe and dramatic declines since the introduction of the Nile Perch. Although numbers of the perch have now decreased, the degradation of the water quality is also thought to be having a significant impact on some fish species. More research is needed to monitor this species and how it is affected by these threats, as well as establishing the extent of its range within the lake. Policy based action is needed to decrease the degradation of the lake, as well as to prevent over fishing. Protected areas should also be established. |
