Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (89 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 45 [19, 111] mg/100g; Iron = 1.41 [0.72, 3.77] mg/100g; Protein = 19.6 [17.4, 21.9] %; Omega3 = 0.448 [0.165, 1.278] g/100g; Selenium = 59.7 [23.4, 133.7] μg/100g; VitaminA = 40.6 [11.6, 141.4] μg/100g; Zinc = 1 [1, 2] mg/100g (wet weight);
