Bayesian length-weight: a=0.01950 (0.01559 - 0.02439), b=3.01 (2.96 - 3.06), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (Ref. 69278):  2.6   ±0.26 se; based on food items.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Fec=600-800).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
