Estimates based on models
Preferred temperature (Ref. 115969): 9 - 22.9, mean 12.8 °C (based on 76 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00433 - 0.01675), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278): 4.3 ±0.70 se; based on food items.
Generation time: 8.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.13; tm=4; tmax=20).
Vulnerability (Ref. 59153): High to very high vulnerability (70 of 100) .
