Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 29, mean 27.8 °C (based on 44 cells).

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

Bayesian length-weight: a=0.01000 (0.00484 - 0.02068), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (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 (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
