Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00437 - 0.01992), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
