Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 4.9, mean 2.8 °C (based on 3132 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.73 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
Nutrients (Ref. 124155):  Calcium = 35 [9, 154] mg/100g; Iron = 0.496 [0.151, 1.617] mg/100g; Protein = 2.86 [0.00, 6.80] %; Omega3 = 0.21 [0.06, 0.75] g/100g; Selenium = 9.05 [2.38, 36.93] μg/100g; VitaminA = 67.2 [8.4, 536.9] μg/100g; Zinc = 0.6 [0.3, 1.5] mg/100g (wet weight);
