Estimates based on models

Preferred temperature (Ref. 123201): 11.8 - 23.8, mean 18.6 °C (based on 84 cells).

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

Bayesian length-weight: a=0.00068 (0.00040 - 0.00113), b=3.30 (3.16 - 3.44), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±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): High vulnerability (60 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 71.3 [44.1, 129.6] mg/100g; Iron = 0.818 [0.480, 1.351] mg/100g; Protein = 17.9 [15.8, 20.4] %; Omega3 = 0.193 [0.085, 0.522] g/100g; Selenium = 93.8 [48.7, 197.0] μg/100g; VitaminA = 15.3 [4.6, 46.6] μg/100g; Zinc = 0.844 [0.625, 1.192] mg/100g (wet weight);
