Estimates based on models

Preferred temperature (Ref. 115969): 4.6 - 9.4, mean 6.1 (based on 78 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00426 - 0.02456), b=3.00 (2.80 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  手段, １．４年～４．４年の倍増期間の最小個体群 (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
