Estimates based on models
Preferred temperature (Ref.
123201): 2 - 17.6, mean 12 °C (based on 260 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7520 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
