Scientific Name:	Haplochromis serranus
Species Authority:	Pfeffer,1896

Assessment Information [top]

Red List Category & Criteria:	Data Deficient     ver 3.1
Year Published:	2010
Assessor/s:	Witte, F. & de Zeeuw, M.P.
Reviewer/s:	Darwall, W. & Smith, K.
Justification: There is no information available on the population size of this species now, or in the past. Presence of the species has never been confirmed in the Tanzania sector of Lake Victoria by the Haplochromis Ecology Survey Team. A lake wide survey is needed before a full assessment can be made.
History:	2006 – Near Threatened (IUCN 2006)

Geographic Range [top]

Range Description:	This species is endemic to Lake Victoria. It has been recorded in surveys carried out in Kenya, Tanzania and Uganda (Greenwood 1981).

Habitat and Ecology [top]

Habitat and Ecology:	The species has been found over mud substrate in the littoral zone. It is classified as a piscivore (sensu stricto).
Systems:	Freshwater

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 predation by Nile Perch (a potentially reversible threat).

Conservation Actions [top]

Conservation Actions:

This species only rarely been reported and more information is needed.
