Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 10.5, mean 5.7 °C (based on 1475 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00274 - 0.00960), b=3.06 (2.90 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 23.9 [11.9, 50.6] mg/100g ; Iron = 0.289 [0.160, 0.535] mg/100g ; Protein = 17.4 [16.0, 18.9] % ; Omega3 = 0.222 [0.113, 0.436] g/100g ; Selenium = 17.7 [7.7, 38.3] μg/100g ; VitaminA = 10.2 [2.1, 46.2] μg/100g ; Zinc = 0.392 [0.261, 0.583] mg/100g (wet weight);
