Africa: Lakes Victoria, Nabugabo and Kyoga, affluent rivers of Lake Victoria, Victoria Nile (Ref. 4903). Also found in the Lake Rukwa drainage (Ref. 27292), the Malagarazi River (Ref. 54847, 98755) and the Middle Akagera system (Ref. 46152, 54979). Specimens from Kingani River (=Ruvu River) are misidentifications of S. orientalis (Ref. 78218).

Length at first maturity / Tamaño / Peso / Age

Maturity: Lm 9.6, range 10 - 12 cm
Max length : 17.7 cm SL macho / no sexado; (Ref. 34290)

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 7. 32-54 mandibular teeth. Maxillary barbels reaching almost to the origin of the pelvic fin in some specimens and to the tip of the humeral process in others. Outer mandibular barbels with slender branches, inner pair with shorter, but slender branches. Marbled yellowish-brown (marbling is extremely variable, some individuals uniformly brown) (Ref. 34290).

Biología     Glosario (por ej. epibenthic)

Lives in streams and rivers and in lakes, where it prefers shore regions (Ref. 78218). More common in rivers than in lakes (Ref. 12526). Common in marginal vegetation of Kagera River (Ref. 4903). Replaces S. victoriae in shallow waters of Lake Victoria (Ref. 4903), prefers areas less than 20 m deep (Ref. 34290). Feeds on insects (Povilla and chironomid larvae) and molluscs (Ref. 12526). Oviparous (Ref. 205). Rarely grows to lengths greater than 15 cm SL (Ref. 34290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Fec = 200).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
