Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00577 - 0.01734), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Generation time: 8.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.124; Tmax=10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
