Estimates based on models
Preferred temperature (Ref. 115969
): 21.9 - 28.3, mean 26.8 °C (based on 847 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02138 (0.01559 - 0.02932), b=2.89 (2.81 - 2.97), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.3 se; based on diet studies.
Generation time: 1.6 (0.9 - 1.8) years. Estimated as median ln(3)/K based on 10 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.6-1.23).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
