Estimates based on models
Preferred temperature (Ref. 123201
): 13.9 - 18.2, mean 15.7 °C (based on 166 cells).
Phylogenetic diversity index (Ref. 82804
= 1.0001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.35 se; based on food items.
Generation time: 20.2 ( 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.).
Fishing Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100).
