Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 29, mean 27.8 °C (based on 44 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00484 - 0.02068), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
