Africa: endemic to Lake Tana and its tributaries, Ethiopia (Ref. 35835, 96382, 128753).

Size / Gewicht / Alter

Maturity: L_m ? range ? - ? cm
Max length : 82.4 cm FL Männchen/unbestimmt; (Ref. 35835)

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 12 - 13; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 8. Lower jaw extending anteriorly of the upper jaw by at least the thickness of the upper lip; upper jaw length more than 1.3 times in lower jaw.

Has a small preference for rocky substrates and waters less than 6 m deep. Is a partial piscivore: specimens smaller than 15 FL mainly eat insect larvae and zooplankton, but also some fish. With size, the amount of fish in the diet increases, as does the amount of plant material, while the amount of insects decreases and zooplankton disappears altogether (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=0.00955 (0.00430 - 0.02123), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.44 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).
