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=0.00617 (0.00365 - 0.01041), b=3.05 (2.90 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
栄養段階 (Ref. 69278):  2.9   ±0.44 se; based on food items.
回復力 (Ref. 120179):  高い, 15か月以下の倍増期間の最小個体群 (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
