Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00229 - 0.01150), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.2 se; based on size and trophs of closest relatives
Generation time: 6.3 ( 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 (K=0.17).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
