Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.7   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  非常に低い, １４年以上の倍増期間の最小個体群 (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
