Also caught with drawnets. The habitat preferences are strongly influenced by the presence or absence of the tigerfish Hydrocynus forskahlii: if the tigerfish is absent, S. thumbergi is found in open waters and sometimes in fast-flowing rocky habitats; in areas where the tigerfish occurs, S. thumbergi is relegated to lagoons, backwaters and marshy shallow areas. Feeds on small fish, insects and snails (Ref. 6465).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.7 ±0.61 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
