Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01799 - 0.03055), b=2.97 (2.89 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.29 se; based on food items.
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.18).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100). 🛈
