Estimates based on models

Preferred temperature (Ref. 123201): 19.4 - 28.6, mean 24.7 °C (based on 86 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01660 (0.00788 - 0.03495), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 3.6 ±0.53 se; based on food items.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
