Estimates based on models
Preferred temperature (Ref. 115969
): -0.4 - 6.9, mean 2.4 °C (based on 1768 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00390 - 0.01344), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.3 se; based on diet studies.
Generation time: 7.3 ( 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 Fec=10-100).
Vulnerability (Ref. 59153
): High vulnerability (56 of 100) .
