Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 11.8, mean 5.4 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00309 - 0.01123), b=3.12 (2.96 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.3   ±0.67 se; based on food items.
Daya lenting (Ref. 120179):  Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
