Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 2.9, mean 2.2 °C (based on 2666 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00110 (0.00040 - 0.00297), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 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): Moderate to high vulnerability (45 of 100).
