Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00589 - 0.03714), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
Nutrients (Ref. 124155):  Calcium = 53.5 [23.8, 107.4] mg/100g; Iron = 0.481 [0.263, 0.937] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.418 [0.207, 0.832] g/100g; Selenium = 8.49 [3.73, 20.12] μg/100g; VitaminA = 10.2 [2.1, 49.2] μg/100g; Zinc = 0.777 [0.501, 1.244] mg/100g (wet weight);
