Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00736 - 0.02360), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.2 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 61.8 [33.9, 106.0] mg/100g; Iron = 0.918 [0.543, 1.543] mg/100g; Protein = 18.7 [17.8, 19.7] %; Omega3 = 0.225 [0.141, 0.365] g/100g; Selenium = 25.6 [12.0, 51.7] μg/100g; VitaminA = 7.28 [2.17, 23.12] μg/100g; Zinc = 0.635 [0.459, 0.929] mg/100g (wet weight);
