Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00316 - 0.01588), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 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): Low vulnerability (24 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 240 [149, 509] mg/100g; Iron = 2.27 [1.38, 3.97] mg/100g; Protein = 17.7 [16.8, 18.7] %; Omega3 = 0.495 [0.208, 1.226] g/100g; Selenium = 61.4 [25.9, 132.8] μg/100g; VitaminA = 77.1 [24.9, 241.0] μg/100g; Zinc = 1.81 [1.18, 2.74] mg/100g (wet weight);
