Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00221 - 0.00624), b=3.12 (2.98 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.59 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179):  низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
