Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) C2a(ii) ver 3.1
Year Published: 2010
Date Assessed: 2010-03-31
Assessor(s): Witte, F., de Zeeuw, M.P. & Brooks, E.
Reviewer(s): Darwall, W. & Smith, K.
The species 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 1985. If it is still present it is likely to be extremely rare with very few individuals, but it may now be Extinct.
Date last seen: 1985
Previously published Red List assessments:
1996 Endangered (EN)

Habitat and Ecology [top]

Habitat and Ecology: This species is restricted to areas in the littoral zone where the substrate is firm (sand, rock). H. barbarae is an egg snatcher (paedophage).
Systems: Freshwater
Generation Length (years): 1

Use and Trade [top]

Use and Trade: An additional threat is capture as bait for long line fishery.

Threats [top]

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 capture as bait for long line fishery.

Conservation Actions [top]

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.
