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=0.00603 (0.00346 - 0.01050), b=3.21 (3.06 - 3.36), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.3 se; based on diet studies.
Generation time: 4.6 (2.9 - 5.8) years. Estimated as median ln(3)/K based on 18
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; k=0.22).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
