Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (tmax=5; Fec=1,200).
Fishing Vulnerability (Ref.
