Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00145 - 0.00660), b=3.22 (3.04 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  High vulnerability (57 of 100) .
Nutrients (Ref. 124155):  Calcium = 10.6 [1.8, 32.9] mg/100g ; Iron = 0.276 [0.061, 0.695] mg/100g ; Protein = 15.6 [13.2, 17.9] % ; Omega3 = 0.421 [0.164, 1.218] g/100g ; Selenium = 16 [4, 49] μg/100g ; VitaminA = 8.46 [2.28, 28.79] μg/100g ; Zinc = 0.347 [0.172, 0.747] mg/100g (wet weight);
