Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00145 - 0.00994), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
Nutrients (Ref. 124155):  Calcium = 124 [52, 236] mg/100g; Iron = 1.1 [0.6, 2.0] mg/100g; Protein = 17.4 [16.2, 18.6] %; Omega3 = 0.235 [0.089, 0.619] g/100g; Selenium = 42.2 [16.7, 97.1] μg/100g; VitaminA = 62.3 [20.7, 164.9] μg/100g; Zinc = 1.91 [1.31, 2.77] mg/100g (wet weight);
