Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 29, mean 27.5 (based on 294 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.00 (2.82 - 3.18), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tm=4; K=0.428; Tmax=25).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
