Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), 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
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
Nutrients (Ref.
124155): Calcium = 9.24 [1.36, 163.43] mg/100g; Iron = 0.272 [0.025, 3.201] mg/100g; Protein = 19.9 [14.7, 25.0] %; Omega3 = 0.322 [0.090, 1.016] g/100g; Selenium = 6.26 [1.27, 32.37] μg/100g; VitaminA = 10.6 [0.8, 130.6] μg/100g; Zinc = 0.507 [0.038, 5.706] mg/100g (wet weight);
