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=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Assuming Fec < 100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
