50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00375 - 0.01534), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.40 se; based on food items.
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
