Preferred temperature (Ref. 115969
): 9.1 - 18.5, mean 14.4 °C (based on 37 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00206 - 0.00735), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.30 se; based on food items.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
