Estimates based on models

Preferred temperature (Ref. 115969): 16.3 - 25.9, mean 19.8 °C (based on 38 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00131 - 0.00635), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.6 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  Moderate vulnerability (42 of 100) .
