Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00332 - 0.00998), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.3 se; based on size and trophs of closest relatives
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13-0.24).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (45 of 100).
