50 = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00178 - 0.00775), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 3.2 ±0.1 se; based on diet studies.
回復力 (Ref.
120179): 高い, １５か月以下の倍増期間の最小個体群 (tm=1; tmax=1).
Fishing Vulnerability (Ref.
