Biology     Glossary (e.g. epibenthic)

Oviparous (Ref. 205). Inhabits small streams, main rivers and flooded pools (Ref. 30558). Extremely abundant in ox-bow lakes and river cut-offs in the Lower Tana River (Ref. 39831). Breeding occurs shortly after floods, when ripe fish enter small streams leading to floodwater pools, where they breed; this migration is rather sudden, adult fish migrate in large schools upstream over a period of less than a week (3 to 4 days); one or two additional smaller migrations may occur after the main peak; the stimulus triggering this migration is probably closely connected with rainfall (Ref. 96595).

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=0.00617 (0.00255 - 0.01493), b=3.09 (2.88 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
Price category (Ref. 80766):   Unknown.
