Estimates based on models
Preferred temperature (Ref.
123201): 23.3 - 27.6, mean 24.4 °C (based on 167 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00569 - 0.02662), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.3 ±0.0 se; based on diet studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
