Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 11 - 13; Anal spines: 3; Anal soft rays: 10 - 11. Diagnosis: Relatively shallow body with flat dorsal profile; relatively large, upwardly-pointing mouth with strongly protruding lower jaw; large number of gill-rakers (Ref. 55949).

Biology     Glossary (e.g. epibenthic)

Found in open water at mostly deep levels, where it can form enormous shoals (Ref. 5595). It is a piscivore that mainly feeds on lake sardine, Engraulicypris sardella (Ref. 5595).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 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), in cm total length, 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. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 125 [66, 251] mg/100g; Iron = 1.48 [0.83, 2.86] mg/100g; Protein = 18.5 [16.9, 20.0] %; Omega3 = 0.607 [0.214, 1.783] g/100g; Selenium = 72.9 [28.3, 177.9] μg/100g; VitaminA = 109 [25, 378] μg/100g; Zinc = 1.61 [1.07, 2.49] mg/100g (wet weight);
