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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高い, １５か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 500 [302, 1,184] mg/100g; Iron = 3.03 [1.80, 5.47] mg/100g; Protein = 17.5 [16.6, 18.5] %; Omega3 = 0.606 [0.244, 1.610] g/100g; Selenium = 48.2 [19.5, 118.7] μg/100g; VitaminA = 126 [41, 391] μg/100g; Zinc = 2.46 [1.55, 3.81] mg/100g (wet weight);
