Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00056 (0.00035 - 0.00091), b=3.28 (3.15 - 3.41), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 27.4 [17.3, 47.3] mg/100g; Iron = 0.302 [0.183, 0.486] mg/100g; Protein = 18.3 [16.1, 20.7] %; Omega3 = 0.49 [0.23, 1.22] g/100g; Selenium = 17.2 [9.6, 32.0] μg/100g; VitaminA = 11.6 [3.0, 41.4] μg/100g; Zinc = 0.446 [0.333, 0.604] mg/100g (wet weight);
