Lengte bij maturiteit / Grootte / Gewicht / Leeftijd

Maturity: L_m ?, range 10 - ? cm
Max length : 26.0 cm TL mannelijk / geslacht onbekend; (Ref. 52331)

In Lake Kyoga in or near water lily swamps (Ref. 49805). In Lake Victoria in shallow inshore waters over both sandy and rocky bottoms, and seasonally over muddy bottoms adjacent to extensive papyrus swamps (Ref. 9606). Predominantly insectivorous, feeding mainly on chironomid larvae (Ref. 12526), but also feeds on small organisms like Ostracoda, Hydracarina (Ref. 9606, 12526), Conchostraca (Ref. 12526) and Diaptomus (Ref. 9606). Crustaceans, gastropods, fish eggs and detritus are also taken (Ref. 9606). Males grow to larger size than females; breeds twice a year during rainy seasons; migrates up the river to spawn (Ref. 10608). Oviparous (Ref. 205).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01380 (0.00615 - 0.03096), b=2.86 (2.69 - 3.03), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.36 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Fec = 846).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
