Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00654 - 0.01108), b=3.03 (2.99 - 3.07), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 7.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (K=0.14-0.18; Fec=64,770).
Fishing Vulnerability (Ref.
59153): High vulnerability (58 of 100).
Nutrients (Ref.
124155): Calcium = 125 [35, 217] mg/100g; Iron = 0.827 [0.504, 1.466] mg/100g; Protein = 16.6 [15.7, 17.4] %; Omega3 = 0.374 [0.148, 0.973] g/100g; Selenium = 389 [152, 1,069] μg/100g; VitaminA = 11.3 [4.6, 29.8] μg/100g; Zinc = 1.24 [0.67, 2.40] mg/100g (wet weight); based on
nutrient studies.
