Estimates based on models
Preferred temperature (Ref. 123201): 3.4 - 5, mean 4.2 °C (based on 340 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00154 - 0.01080), b=3.17 (2.94 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.4 ±0.5 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 (21 of 100).
Nutrients (Ref. 124155): Calcium = 28.6 [7.2, 123.0] mg/100g; Iron = 0.482 [0.141, 1.518] mg/100g; Protein = 3.01 [0.00, 7.02] %; Omega3 = 0.189 [0.059, 0.607] g/100g; Selenium = 15.5 [3.8, 66.6] μg/100g; VitaminA = 16.9 [1.9, 127.6] μg/100g; Zinc = 0.609 [0.279, 1.516] mg/100g (wet weight);
