Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00214 - 0.01021), b=3.12 (2.92 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100).
