Estimates based on models
Preferred temperature (Ref.
123201): 7.6 - 15.9, mean 10.7 °C (based on 818 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00194 - 0.00745), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.4 ±0.63 se; based on food items.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
