Estimates based on models
Preferred temperature (Ref. 115969
): 19.3 - 26.2, mean 22.6 °C (based on 171 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Fec = 224,960).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
