Morphology | Morphometrics
Diagnosis: relatively shallow body with flat dorsal profile; relatively large, upturned mouth with strongly protruding lower jaw; large number of gill-rakers (Ref. 55949).
Occurs in open water at mostly deep levels, where it can form enormous shoals. Feeds on fishes, mainly on lake sardine, Engraulicypris sardella (Ref. 5595).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.73 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
