Estimates based on models
Preferred temperature (Ref. 115969
): 13.2 - 26.4, mean 19.7 °C (based on 196 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00289 - 0.00830), b=3.06 (2.91 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.63 se; based on food items.
Generation time: 3.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.34-0.38).
