Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.502 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.0 ±0.3 se; Based on food items.
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing vulnerability (Ref. 59153): Low vulnerability (10 of 100).
Nutrients (Ref. 124155): Calcium = 0 [0, 0] mg/100g; Iron = 0 [0, 0] mg/100g; Protein = 0 [0, 0] %; Omega3 = 0 [0, 0] g/100g; Selenium = 0 [0, 0] μg/100g; VitaminA = 0 [0, 0] μg/100g; Zinc = 0 [0, 0] mg/100g (wet weight);
