Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.3, mean 28.3 °C (based on 2469 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00047 (0.00025 - 0.00089), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
