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
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), 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.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100).
