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=0.00295 (0.00131 - 0.00665), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this Genus-BS (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 19.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Widerstandsfähigkeit (Ref.
120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (86 of 100).
