Bayesian length-weight: a=0.01072 (0.00875 - 0.01312), b=2.97 (2.94 - 3.00), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.14-0.38; tmax=6).

Prior r = 0.55, 95% CL = 0.36 - 0.82, Based on 1 full stock assessment.
