Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.6270   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.1   ±0.0 se; based on diet studies. Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5; K=0.26). Fishing Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (34 of 100). Price category (Ref. 80766 ):   Unknown .
