50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00408 - 0.02815), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.3 ±0.1 se; based on diet studies.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
Nutrients (Ref.
124155): Calcium = 56.9 [23.5, 115.3] mg/100g; Iron = 1.01 [0.58, 1.70] mg/100g; Protein = 18.9 [18.0, 20.0] %; Omega3 = 0.486 [0.190, 1.221] g/100g; Selenium = 20.7 [8.5, 51.7] μg/100g; VitaminA = 39.3 [13.0, 116.3] μg/100g; Zinc = 1.31 [0.92, 1.92] mg/100g (wet weight);
