Estimates based on models
Preferred temperature (Ref.
123201): 20.8 - 28.5, mean 24.7 °C (based on 42 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.01011 - 0.01799), b=3.10 (3.04 - 3.16), in cm total length, based on LWR estimates for this species (Ref.

Trophic level (Ref.
69278): 3.2 ±0.45 se; based on food items.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=1.09-1.2;).
