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=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
