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=0.00562 (0.00251 - 0.01261), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
