50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00203 - 0.01424), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
