Estimates based on models

Preferred temperature (Ref. 123201): 3.1 - 3.9, mean 3.4 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 41.2 [16.1, 170.5] mg/100g; Iron = 0.409 [0.143, 1.329] mg/100g; Protein = 2.86 [0.00, 6.84] %; Omega3 = 0.272 [0.074, 0.913] g/100g; Selenium = 6.01 [1.80, 24.45] μg/100g; VitaminA = 130 [16, 1,230] μg/100g; Zinc = 0.798 [0.411, 1.657] mg/100g (wet weight);
