Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00524 - 0.01907), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.22 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
