Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Afterflossenweichstrahlen: 14 - 16. It has a prominent lateral ethmoid that forms a "shelf" between the eye and the nostrils (Ref. 56505), two pairs of vomerine toothpletes (Ref. 56505), and a very short adipose-fin base (Ref. 56505). Body dark brown, lower surfaces completely covered with fine brown pigment specks (Ref. 3976).

Found along the coast (Ref. 5213). Enters the lower parts of rivers of the east coast of Africa (Ref. 3876). Feeds on invertebrates and small fishes. Marketed fresh and dried-salted (Ref. 3290). Males incubate eggs in its mouth(Ref. 68964). Air bladder utilized for isinglass.

Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 28.7, mean 27.4 °C (based on 76 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00547 - 0.01386), b=3.02 (2.89 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.62 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tmax=7; k=0.16-0.7).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Preiskategorie (Ref. 80766): Medium.
