Bayesian length-weight: a=0.01023 (0.00655 - 0.01599), b=2.98 (2.85 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.4 se; based on size and trophs of closest relatives
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
