Bayesian length-weight: a=0.01000 (0.00601 - 0.01665), b=3.01 (2.86 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.47 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (tmax=6).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
