Estimates based on models
Preferred temperature (Ref.
123201): 11.9 - 13.5, mean 12.6 °C (based on 6 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00372 - 0.01775), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100).
