Estimates based on models

Preferred temperature (参照 123201): 24.4 - 28, mean 26.7 °C (based on 64 cells).
Phylogenetic diversity index (参照 82804):  PD50 = 0.5006   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00153 - 0.00788), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (参照 69278):  4.5   ±0.54 se; based on food items.
回復力 (参照 120179):  低い, 4.5年~14年の倍増期間の最小個体群 (Fec=24).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
価格帯 (Ref. 80766):   High.
