Estimates based on models

Preferred temperature (Ref. 123201 ): 24.6 - 28.6, mean 27.5 °C (based on 26 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00069 (0.00033 - 0.00144), b=3.12 (2.93 - 3.31), 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 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (42 of 100).
