Estimates based on models

Preferred temperature (Ref. 123201): 5 - 9.5, mean 6.4 °C (based on 74 cells).

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

Bayesian length-weight: a=0.00141 (0.00076 - 0.00261), b=3.43 (3.27 - 3.59), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.65 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 47.5 [27.5, 92.5] mg/100g; Iron = 0.393 [0.228, 0.696] mg/100g; Protein = 18.2 [16.0, 20.3] %; Omega3 = 0.46 [0.25, 0.78] g/100g; Selenium = 15.6 [7.8, 30.7] μg/100g; VitaminA = 23.5 [6.8, 78.6] μg/100g; Zinc = 0.509 [0.363, 0.715] mg/100g (wet weight);
