Attributs

DISTRIBUTION: Lien Faunafri
Biology : Petr & Paperna, 1979 .
Colour pattern : De Vos & Thys van den Audenaerde, 1990a .
Common names : Parmicka nyanzanska (Czech), Nyanza barb (English), Nyanza pardkala (Estonian), Hohtojuovabarbi (Finnish), Nyanzabarbe (German), Kandhira (Luo: Kenya), Ikinanga / Inkwekwe [Rwanda (Kinyarwanda): Rwanda] .
Current distribution known : occurs in Lake Victoria and affluents rivers such as the Nzoia River and the Nyando River. It has also been reported from the Middle Akagera system, downstream of the Rusumo Falls, in Rwanda. Within the main lake there are few confirmed localities but this may be due to difficulties in identification rather than restricted range .
Distribution_references : De Vos & Thys van den Audenaerde, 1990a .
Food habits / trophic level : feeds predominantly on insect larvae .
Genetics : Colli et al., 2009 | Ndeda et al., 2018 | Schmidt, 2014 | Tsigenopoulos et al., 2002 | Yang et al., 2015 .
Habitat / home range : found in streams, rivers and lakes. In the Lake Victoria system it appears in rivers and lake-side streams during rains, and in the dry season it is found along the shores of the lake (adults) or in floodwater pools (juveniles) .
Migration / movement : considered to be potamodromous; half-grown fishes migrate into rivers and down to the lake at the next flood .
Morphology / anatomy : De Vos & Thys van den Audenaerde, 1990a .
Phylogeny : Colli et al., 2009 | Hayes & Armbruster, 2017 | Ndeda et al., 2018 | Schmidt, 2014 | Tsigenopoulos et al., 2002 | Yang et al., 2015 .
Reproduction : the principal spawning grounds appear to be the floodwater pools, but breeding may also occur among the grasses at the edges of rivers .
Size : 70 mm SL .
