Estimates based on models
Preferred temperature (Ref.
123201): 1.3 - 2.5, mean 1.8 °C (based on 23 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00058 - 0.00275), b=3.47 (3.29 - 3.65), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.54 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tm=4; Fec = 2,770).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
Climate Vulnerability (Ref.
