Estimates based on models
Preferred temperature (Ref.
123201): 1.5 - 10.2, mean 2.5 °C (based on 14 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10; K=0.49-0.62).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (32 of 100).
