Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29.2, mean 28.3 °C (based on 1510 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00717 - 0.01755), b=3.06 (2.94 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.69 se; based on food items.
Generation time: 1.6 (0.8 - 2.1) years. Estimated as median ln(3)/K based on 14 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.53-1.94).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
