Estimates based on models
Preferred temperature (Ref. 115969): 23.5 - 28.6, mean 27.5 °C (based on 707 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.01184 - 0.01468), b=2.93 (2.90 - 2.96), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.9 ±0.64 se; based on food items.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13(?)-0.35; Fec=146,400).
Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100) .
