Scientific Name:	Oreochromis ndalalani
Species Authority:	Seegers & Tichy, 1999

Assessment Information [top]

Red List Category & Criteria:	Vulnerable   D2   ver 3.1
Year Assessed:	2006
Assessor/s:	Hanssens, M. & Snoeks, J.
Reviewer/s:	Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification: Only known from three localities in the south of the Lake Natron drainage. Such a restricted distribution makes it more vulnerable to local habitat degradation.

Geographic Range [top]

Range Description:	Only known from the Southern Lagoon of Lake Natron, where it inhabits the springs and effluent stream at Olomotony and some spring-fed creeks entering this lagoon from the southeast and east (Seegers and Tichy 1999).
Countries:	Native: Tanzania, United Republic of

Habitat and Ecology [top]

Habitat and Ecology:

Springs and creeks near the southern and southeastern shores of Lake Natron. The water of these springs is usually clean, but the creeks near the main lake carry turbid water and many of the inhabited creeks are also polluted by cattle or game (Seegers and Tichy 1999). They graze stones and gravel, probably taking mainly algae for food but are clearly omnivorous taking insects from the water surface as well (Seegers and Tichy 1999). They are maternal mouthbrooders (Seegers and Tichy 1999).

Systems:

Freshwater
