Estimates based on models
Preferred temperature (Ref.
123201): 2.9 - 5.3, mean 3.8 °C (based on 20 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00506 - 0.02166), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=7).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
