Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 8 - 10 cm
Max length : 35.0 cm SL male/unsexed; (Ref. 34290)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6-7. 16-21 mandibular teeth. Maxillary barbels reaching posterior tip of the humeral process, or occasionally beyond. Mandibular barbels with slender branches. Greyish silver, with dark spots of variable size. Caudal fin occasionally spotted (Ref. 34290).

Biology     Glossary (e.g. epibenthic)

Occurs in rivers and lakes and prefers deeper water (0-80 m) (Ref. 34291), although it also occurs in shallow water (Ref. 34290). In Lake Victoria it occurs over hard and soft substrates, but is more common over soft bottoms and in water over 13 m deep; feeds on gastropod molluscs and insects (mainly chironomid larvae), and to a minor extent on fishes and ostracoda; able to extract the flesh of snails without crushing their shells (Ref. 12526). Rarely grows to lengths greater than 35 cm SL (Ref. 34290). Oviparous (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 205). Distinct pairing during breeding (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00643 - 0.02466), b=2.94 (2.77 - 3.11), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.48 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,500).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
