Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00550 - 0.00793), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
Niveau trophique (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming tm=5-10).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (83 of 100).
