Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=3.06 (2.87 - 3.25), 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):  高い, １５か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
