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=0.01148 (0.00543 - 0.02429), b=2.98 (2.81 - 3.15), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (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) .
