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=0.00741 (0.00382 - 0.01439), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Generation time: 7.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (tmax=15; K=0.15).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
