Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.1, mean 28.4 °C (based on 648 cells).

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

Bayesian length-weight: a=0.00832 (0.00477 - 0.01449), b=3.10 (2.95 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
