Estimates based on models
Preferred temperature (Ref. 115969
): 25.9 - 28.4, mean 27 °C (based on 96 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00752 - 0.00919), b=3.06 (3.03 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.62 se; based on food items.
Generation time: 2.1 (1.8 - 2.2) 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=0.5; Fec=112,523).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
