Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7502 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.3 ±0.3 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (25 of 100).
