Bayesian length-weight: a=0.01349 (0.00788 - 0.02308), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.38 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=6; Fec=29,000).
Vulnerability (Ref. 59153
