Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00483 - 0.01139), b=2.90 (2.78 - 3.02), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.58 se; based on food items.

Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming tm=1-2, Fec>1,000).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).

Price category (Ref. 80766): Unknown.
