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=0.01318 (0.00612 - 0.02839), b=2.85 (2.67 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
Price category (Ref. 80766):   Unknown.
