Estimates based on models
Preferred temperature (Ref.
123201): 16.8 - 20.9, mean 18.2 °C (based on 44 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00372 - 0.01775), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
Nutrients (Ref.
124155): Calcium = 5.64 [0.60, 88.84] mg/100g; Iron = 0.407 [0.034, 4.430] mg/100g; Protein = 21.2 [15.8, 26.4] %; Omega3 = 0.121 [0.037, 0.361] g/100g; Selenium = 11.4 [2.0, 57.9] μg/100g; VitaminA = 27.4 [2.3, 320.2] μg/100g; Zinc = 0.618 [0.043, 7.077] mg/100g (wet weight);
