Estimates based on models
Preferred temperature (Ref.
123201): 24.8 - 29.2, mean 28.3 °C (based on 1334 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00260 - 0.00734), b=3.05 (2.91 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.1 se; based on diet studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (25 of 100).
