Estimates based on models
Preferred temperature (Ref. 123201
): 25.8 - 28.2, mean 27.3 °C (based on 315 cells).
Phylogenetic diversity index (Ref. 82804
= 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
): 4.1 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
