Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00912 (0.00290 - 0.02870), b=2.98 (2.72 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.0   ±0.3 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
