Estimates based on models

Preferred temperature (Ref. 115969): 24.3 - 29.1, mean 27.5 (based on 26 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00570 - 0.01458), b=3.03 (2.90 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.5 ±0.37 se; based on food items.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
