Estimates based on models

Preferred temperature (Ref. 123201): 6.8 - 13.5, mean 9.4 °C (based on 76 cells).

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

Bayesian length-weight: a=0.00562 (0.00353 - 0.00895), b=3.07 (2.94 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

Nutrients (Ref. 124155): Calcium = 110 [16, 2,849] mg/100g; Iron = 1.33 [0.12, 18.12] mg/100g; Protein = 14.6 [12.9, 16.4] %; Omega3 = 0.69 [0.17, 2.70] g/100g; Selenium = 6.27 [0.76, 40.18] μg/100g; VitaminA = 224 [11, 4,346] μg/100g; Zinc = 1.74 [0.13, 20.44] mg/100g (wet weight); based on nutrient studies.
