Africa: Lake Tana, Ethiopia (Ref. 35835, 128753). Also Didessa River in Ethiopia, but occurrences outside Lake Tana would suggest dispersion (Ref. 35835).

Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 12 - 13; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 8. Head width less than 1.8 times in head length; head length more than 1.3 times in body depth; body depth less than 3.6 times in standard length; eye diameter more than 1.3 times in interorbital width; dark green; often with an extended, soft abdomen.

Occurs over muddy, sandy and rocky substrates all over the lake, preferably in water of no more than 3 m depth. Is a real macrophytivore: specimens smaller than 15 cm feed mainly on zooplankton and insect larvae; macrophytes increase in importance with size and finally make up most of the diet (Ref. 35835).

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=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.9 ±0.34 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).
