Estimates based on models

Preferred temperature (Ref. 123201): 22.9 - 27, mean 24.2 °C (based on 124 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00122 - 0.00544), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±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 vulnerability (10 of 100).
