Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 13; Anal soft rays: 8. Well developed lips with round chin lobe. Last simple ray strongly ossified forming thick dorsal spine in adults (grows allometrically, shorter than the head of young and longer than head length in individual > 15 in SL). Longest dorsal ray is the 1st branched ray. Upper edge of dorsal fin slightly concave. Gill rakers in 1st branchial arch. Yellowish, slightly orange on sides, grayish back, fins more ore less yellowish. Caudal orange in young and individuals of middle size, grayish in adults. Black margin on caudal and dorsal fins.

Biology     Glossary (e.g. epibenthic)

Feed on crustaceans, insects, mollusks and organic debris. In the Jebel Aulia Reservoir, annual spawning coincides with the onset of the floods. Fecundity estimates ranged from 72 x 1,000 at 33 cm (4 yrs.) to over 14 x 10,000 at 74 cm (8 yrs).

Bayesian length-weight: a=0.00918 (-0.15001 - 0.16837), b=3.08 (2.99 - 3.16), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.26).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
