Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.01154 - 0.03004), b=3.01 (2.88 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
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 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
