Estimates based on models
Preferred temperature (Ref. 123201
): 27.1 - 29.1, mean 28.4 °C (based on 694 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00112 (0.00044 - 0.00288), b=3.05 (2.82 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (48 of 100).
