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=0.00575 (0.00329 - 0.01007), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.13-0.24).
Fishing Vulnerability (Ref.
