Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00922 - 0.04317), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 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 vulnerability (11 of 100).
Nutrients (Ref. 124155):  Calcium = 28.5 [13.7, 61.4] mg/100g; Iron = 0.41 [0.08, 0.97] mg/100g; Protein = 16.4 [13.7, 18.7] %; Omega3 = 0.311 [0.138, 0.652] g/100g; Selenium = 14.5 [5.6, 36.1] μg/100g; VitaminA = 15.7 [2.5, 111.7] μg/100g; Zinc = 0.487 [0.303, 0.856] mg/100g (wet weight);
