Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.01008 - 0.02272), b=3.00 (2.88 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.2 ±0.1 se; based on size and trophs of closest relatives
Generation time: 1.9 ( 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 (tm=2-3; tmax=5).
Fishing Vulnerability (Ref.
59153): Low vulnerability (23 of 100).
