Estimates based on models
Preferred temperature (Ref. 115969
): 15 - 27.9, mean 26.1 °C (based on 464 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00738 - 0.01181), b=2.98 (2.92 - 3.04), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.63 se; based on food items.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.13).
