Eccles, D.H. Field
guide to the freshwater fishes of Tanzania (2)
Large teeth, 19 to 33 on lower jaw. Humeral process
narrowly pointed, upper edge concave. Dorsal fin rays
spotted. This species is closely related to S.
both probably deriving from a common ancestor, with
S. ruandae evolving seperately as a result
of its isolation in the upper Kagera drainage (Seegers
2008). Not often seen if at all in imports. Habitat:
Synodontis ruandae is endemic to the Akagera
River system in Rwanda and Burundi. It occurs at five
locations in the Middle and Upper Akagera and has
an ongoing threat from regression of swamps and wetlands
due to agricultural activities, sedimentation due
to erosion on watershed and eutrophication contribute
to continuing declines in habitat quality. Fishing
pressure is also a potential threat. Diet:
Main component of diet is insect larvae, followed
by molluscs. Remarks:
In the IUCN Red List of Threatened Species it is classed
as vunerable and listed as VU D2. It is also close
to meeting the area requirements under Criterion B
1, with an extent of occurrence (EOO) of 21,500 km²
