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=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 236 [131, 477] mg/100g; Iron = 1.87 [1.03, 3.70] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.503 [0.177, 1.439] g/100g; Selenium = 61.4 [24.1, 162.8] μg/100g; VitaminA = 62 [14, 176] μg/100g; Zinc = 3.08 [2.06, 4.69] mg/100g (wet weight);
