Estimates based on models
Preferred temperature (Ref.
123201): 7.9 - 11.1, mean 9.5 °C (based on 14 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00129 - 0.00562), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<4).
Fishing Vulnerability (Ref.
59153): High vulnerability (60 of 100).
Climate Vulnerability (Ref.
125649): Very high vulnerability (89 of 100).
