Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 29, mean 26.4 °C (based on 231 cells).

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

Bayesian length-weight: a=0.01230 (0.00648 - 0.02335), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100).
