Biología     Glosario (por ej. epibenthic)

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).

Phylogenetic diversity index (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).
Nivel trófico (Ref. 69278):  3.4   ±0.36 se; based on food items.
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Fec = 846).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
