Estimates based on models
Preferred temperature (Ref.
123201): 4.7 - 9.5, mean 6.3 °C (based on 463 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00072 (0.00032 - 0.00166), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming fecundity > 100).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (67 of 100).
