Estimates based on models
Preferred temperature (Ref. 123201
): 23.8 - 28.1, mean 27.3 °C (based on 744 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00044 - 0.00239), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±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
): Low to moderate vulnerability (35 of 100).
