Estimates based on models
Preferred temperature (Ref. 123201
): 0.8 - 21.9, mean 8.6 °C (based on 1055 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00681 - 0.02123), b=3.15 (2.99 - 3.31), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.2 se; based on diet studies.
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.08-0.11).
Fishing Vulnerability (Ref. 59153
): High to very high vulnerability (67 of 100).
