Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on diet studies.
Generation time: 5.2 ( 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=0.21; tmax=9; tm=5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
