Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 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).
