Estimates based on models
Preferred temperature (Ref. 115969
): 4.5 - 13.5, mean 8.5 °C (based on 237 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00189 - 0.00529), b=3.17 (3.02 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±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
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (70 of 100) .
