Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00287 - 0.01207), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Generation time: 5.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Tmax=8; k=0.18; Fec=20,000).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
