Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Nutrients (Ref. 124155): Calcium = 108 [66, 183] mg/100g; Iron = 0.987 [0.593, 1.603] mg/100g; Protein = 18 [16, 21] %; Omega3 = 0.169 [0.075, 0.444] g/100g; Selenium = 66.6 [35.4, 134.2] μg/100g; VitaminA = 13.3 [4.2, 39.5] μg/100g; Zinc = 0.942 [0.707, 1.285] mg/100g (wet weight);
