Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00618 - 0.02945), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
Nutrients (Ref. 124155):  Calcium = 109 [54, 218] mg/100g; Iron = 1.11 [0.52, 1.99] mg/100g; Protein = 17.1 [14.4, 20.1] %; Omega3 = 0.283 [0.168, 0.500] g/100g; Selenium = 40.5 [20.2, 84.9] μg/100g; VitaminA = 32.6 [10.8, 107.1] μg/100g; Zinc = 1.09 [0.75, 1.64] mg/100g (wet weight);
