Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5; k=0.19).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
