Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.01102 - 0.02869), b=2.87 (2.73 - 3.01), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.1 se; based on diet studies.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=1.20; tm=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
