Bayesian length-weight: a=0.00537 (0.00312 - 0.00923), b=3.15 (3.00 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (tm=7).
Fishing Vulnerability (Ref. 59153
