Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00598 - 0.01751), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278): 2.3 ±0.27 se; based on food items.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (K=0.35; Fec = 701;).
Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).
