Etymology: Distichodus: Greek, di = two + Greek, stix, stichos = line, row (Ref. 45335);  fasciolatus: "fasciolatus" is derived from the Latin word "fascia"= "band, bandage, girdle, zone, strip, stripe" with "fasciola" as a diminutive (Brown 1956) and most probably refers to the well-marked transverse bars on the flanks (Ref. 96324).   More on author: Boulenger.

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: widespread Congo basin endemic, present from the marine lower Congo up to the upper Lualaba (Ref. 96324). Absent from Luapula-Moero (Ref. 2970, 96324). Reports from Lake Tanganyika (Ref. 4967, 6770, 36901) questionable and probably incorrect (Ref. 96324).

Biology     Glossary (e.g. epibenthic)

Inhabits rivers, rarely in lakes (Ref. 4967). Feeds on plants (Ref. 13371).

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 (0.00549 - 0.02888), b=3.01 (2.81 - 3.21), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
Price category (Ref. 80766):   Unknown.
