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=0.01862 (0.01040 - 0.03333), b=3.09 (2.94 - 3.24), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.7 ±0.33 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=0.7).
Fishing Vulnerability (Ref.
