Estimates based on models

Preferred temperature (Ref. 123201): 23.3 - 27.9, mean 26.4 °C (based on 459 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00407 (0.00237 - 0.00700), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tm<1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
