Estimates based on models
Preferred temperature (Ref. 123201
): 3.7 - 6.6, mean 5.4 °C (based on 51 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00492 - 0.02031), 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
): 3.8 ±0.5 se; based on size and trophs of closest relatives
Generation time: 7.4 ( 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=0.15-0.18; tmax=55).
Fishing Vulnerability (Ref. 59153
): High vulnerability (58 of 100).
