| Population: |
The population of this species appears to be increasing. The results from a small trawl transect in the Mwanza Gulf (based on 60 catches from Feb-Jan) show the mean number caught per 10 minutes increase from 0.3 in 1979/80 to 0.7 for 1987/88, 4.6 in 1993/95 to more than 5 for 2006/08. A large trawl transect carried out in northern Mwanza Gulf (based on 7 catches in 1978, and 69 in 1987) showed an increase from a mean of 0 caught per hour in 1978 to 18 in 1987. Between 1999 - 2008, although exact figures are not given, it was reported to be a commonly caught species.

Habitat and Ecology
[top]
| Habitat and Ecology: |
This is a pelagic species from the sub-littoral zone, mainly occurring over mud substrate. It is classified as a zooplanktivore.
|
| Systems: |
Freshwater |
| Major Threat(s): |
The main threat to this species is predation by Nile Perch (a potentially reversible threat). It is also potentially threatened by 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).

| Conservation Actions: |
None known, but the population trend of this species should continue to be monitored.
