Estimates based on models

Preferred temperature (Ref. 123201): 7.7 - 15.3, mean 11.5 °C (based on 271 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Nutrients (Ref. 124155): Calcium = 6.29 [1.78, 20.89] mg/100g; Iron = 0.269 [0.092, 0.742] mg/100g; Protein = 17.1 [14.9, 19.6] %; Omega3 = 0.3 [0.1, 0.8] g/100g; Selenium = 21.4 [6.2, 73.1] μg/100g; VitaminA = 8.37 [1.52, 41.15] μg/100g; Zinc = 0.291 [0.140, 0.580] mg/100g (wet weight);
